Reading data from single data source(Single SQL Query) for two charts in pentaho CDE

Hi guys…!!!

Community Dashboard Editor is the best reporting/dash boarding  tool that I have worked. It’s smart functionality made me love to work with it and exploring the things time by time.

In this post you’ll learn how to fetch different columns from result set of a single query and use them in different analysis purpose in dash boarding.

Recently I needed to work with a single query data source(SQL) of having 3 columns result set …
Lets say there are 3 columns A,B and C where as A column is having some category names and B and C are having some values

A  B   C
————–
abc 2   4
pqr  6   8
xyz 10 5
and etc.

From the result set A&B are on first chart and A&C are on other chart..
Now how ?????? This question leads me to check the “Data sources” section of CDE.

Follow the steps below.

1) Click on the “sqloverjndi” which  you created for your SQL query.
2)  In the properties section you can find an option called “Output options”. Just click on  it.
3) Let’s say you have 3 columns in your result set and these 3 columns takes index values starting from 0 to n.. i.e., A column index is 0 , B column index is 1 and for the C  value 2 is the index.

  NOTE: if you have more numbers of columns you can give as many indexes by clicking “Add” button as many times.
4)For Chart 1:
i) Click on the chart component where you want show A& B columns ( A is category B is value)
ii) In the properties(Click on Advanced properties) click on “Pre Execution”
iii) Write this below code
function f() {
this.chartDefinition.readers = [
{names:’category’, indexes: 0},
{names: ‘value’, indexes: 1},
{indexs: 2}
];
}
Why this {indexs:2} ? if you omit this the values of index2 append to the category names… to eliminate that problem you need to write it.

 5) For Chart2 :
Repeat the steps in in point 4)
Slight changes in code …

function f() {
this.chartDefinition.readers = [
{names:’category’, indexes: 0},
{names: ‘value’, indexes: 2},
{indexs: 1}
];
}

You are done with reading data from single query of 3 columns where 1&2 for one chart and 1&3 for another chart…

Save your dashboard and see the preview.

Extract year,quarter,month & day from date input control in pentaho CDE using java script – MDX Query Scenario

Hello guys…!!

Some times you need to extract the parts(year,month,day) of Date for some specific use..
For example:
Assume you are creating a report with MDX query which has dimension called “Date” having levels “Year”, “Quarter”,”Month” & “Day”.

(Note : Assume your schema is having
Year: yyyy Quarter: 1 or 2 or 3 or 4 Month : 1,2,3,4…….12  Day : 1,2,3…. 31)

Also assume you do not have direct date dimension in your schema (i.e, you do not have a dimension which takes ‘yyyy-MMM-dd’ column.

But, you need to display date(yyyy-QQ-MMM-dd) or (yyyy-MMM-dd) on X-axis of chart.. Remember you are not having any direct date in your schema but have “Date” with year,quarter,month & day as levels.

From your start_date(or end_date) input control you can extract the individuals using the following java script for CDE and use them properly in your MDX date range place.

This should be done in “Pre Execution” section of Chart component

function extract_function(){

tmp_date = new Date(param_start_date);
var quarter = [‘Q1′,’Q2′,’Q3′,’Q4’];
var month = [‘JAN’,’FEB’,’MAR’,’APR’,’MAY’,’JUN’,’JUL’,’AUG’,’SEP’,’OCT’,’NOV’,’DEC’];

param_start_year = tmp_date.getFullYear();
param_start_quarter = q[Math.floor((tmp_date.getMonth()+ 3) / 3)-1];
param_start_month = m[tmp_date.getMonth()];
param_start_day = tmp_date.getDate();

tmp_date = new Date(param_end_date);
param_end_year = tmp_date.getFullYear();
param_end_quarter = q[Math.floor((tmp_date.getMonth()+ 3) / 3)-1];
param_end_month = m[tmp_date.getMonth()];
param_end_day = tmp_date.getDate();

}

NOTE: 
* quarter and month variables are taken as arrays with default values.
* You need to calculate the month and send it to array ..
When you calculate months
1 becomes JAN, 2 becomes FEB and etc as well
When you calculate quarters
1 becomes Q1, 2 becomes Q2, 3 becomes Q3 & 4 becomes Q4

Forget about your problems …!!!! and Meet us @   http://www.helicaltech.com/contact.php

Pentaho BI Server community 4.8 Installation in existing tomcat with PostgreSQL in Linux/ubantu OS

This post teach you how to install the pentaho-bi-server.4.8.0 stable version in tomcat server with postgreSQL database.

I’ve gone through many posts but could not find all the stuff in a single place. I just worked out and sharing the experience with it.
If you find any difficulty in the below steps feel free to drop a mail @ [email protected] for help.

Prerequisites :
1. Pentaho BI server CE 4.8.0 stable
2. tomat 6 server
3. PostgreSQL
4.PuTTY/WinScp

1)  Download the biserver-stable-4.8.0 using the following command in some folder.
Syntax :
wget URLOfTheDownloadLocation
Example:
wget http://sourceforge.net/projects/pentaho/files/Business%20Intelligence%20Server/4.8.0-stable  /biserver-ce-4.8.0-stable.zip

2) After downloading completed unzip it using uznip command.
Syntaz :
unzip .zipfileName
Example:
unzip  biserver-ce-4.8.0-stable.zip
After unzipping you can find two folders .. They are i)administration-console & ii) biserver-ce

3) Install tomcat server externally(archive based installation) in your favorite location.
Example:
I’m taking jasperserver tomcat to install the pentaho server.
[email protected]:/opt/jasperreports-server-cp-5.0.0/apache-tomcat#

4) Executing .sql files in postgresSQL
* You need to build the two databases they are i) hibernate & quartz
*  Reason: You are going to install the pentaho bi server with postgreSQL(not with the hsql which directly comes with the download to interact with the server),hence you need to build the two databases for pentaho server to work properly.
* Where you can find the .sql scripting files ?
Check in the location :

/biserver-ce/data/postgresql
( biserver-ce is the folder where you unzipped in step-2)

Scripting file names:

create_quartz_postgresql.sql
create_repository_postgresql.sql
create_sample_datasource_postgresql.sql
migrate_quartz_postgresql.sql
migration.sql
Commands to run the .sql files from putty :

[email protected]:/opt/jasperreports-server-cp-5.0.0/postgresql/bin# ./psql -U postgres -p 5432 -a -f /home/sadakar/softwares/pentaho/biserver-ce/data/postgresql/
create_quartz_postgresql.sql

In the similar way execute the remaining scripting files.. you just need to change the file name in the above command.

Imp points to NOTE when you run the script files * You need to go to the “bin” folder of postgres installed and run the above command.
* In my case I’m using the the postgresql that installed with jasper server.
* In the above command -U user name -p Port number of the postgreSQL
* Must specify   -a -f  in the command otherwise the script will not run.
* When you run the script it’ll ask you for postgreSQL password : give password as “password”.
If you use any other password for postgres give that password
* When you run the script it’ll ask for database user names :
Open the script files in your fav editor and find this line

CREATE USER pentaho_user PASSWORD ‘password’;
This means for the quartz database password is “password” and for the same follows to other scripting files while executing.

 NOTE:
* Once you execute all the scripting files check the postgreSQL databases whether the “hibernate” and “quartz” databases created or not.
* If you do not find the databases you might done wrong some where , cross check again the steps.
* And find 12 tables in “quartz” database and 1 table in “hiberante”database.

Hmmm… You are not done with the databases actually… b’z you do not have all the tables in “hibernate” database. B’z the scripting files do not have all the data & tables.

I’ll give you the links here to run the scripting files to get the tables.
At present do not think of it. Find this in following steps…!!

5. Changes in config.xml file of tomcat server
* You need to add the following code to the config.xml file
* location of the file : tomcat/confg/context.xml
* In my case the location is :
[email protected]:/opt/jasperreports-server-cp-5.0.0/apache-tomcat/conf#
<contex>
<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource name=”jdbc/Hibernate” auth=”Container” type=”javax.sql.DataSource”
factory=”org.apache.commons.dbcp.BasicDataSourceFactory” maxActive=”20″ maxIdle=”5″
maxWait=”10000″ username=”hibuser” password=”password”
driverClassName=”org.postgresql.Driver” url=”jdbc:postgresql://localhost:5432/hibernate”
validationQuery=”select 1″ />

<Resource name=”jdbc/Quartz” auth=”Container” type=”javax.sql.DataSource”
factory=”org.apache.commons.dbcp.BasicDataSourceFactory” maxActive=”20″ maxIdle=”5″
maxWait=”10000″ username=”pentaho_user” password=”password”
driverClassName=”org.postgresql.Driver” url=”jdbc:postgresql://localhost:5432/quartz”
validationQuery=”select 1″/></Context> 
6. Adding postgresql-driver in the lib folder of tomcat
* You need to copy the postgresql-driver in the lib folder of tomcat
* location of the lib folder for tomcat is :  tomcat/lib
* In my example it is there at
[email protected]:/opt/jasperreports-server-cp-5.0.0/apache-tomcat/lib# 
* You can directly download the postgresql driver using the following command or copy and paste it in lib folder if you are already using in some other place in your machine.
* Command is :
wget jdbc.postgresql.org/download/postgresql-9.2-1003.jdbc4.jar
 
7. Changes need to do inside pentaho-solutions folder

* This is quite interesting thing to work here.
* Before you do modifications in pentaho-solutions folder, you need to copy this folder similar to tomcat installation location( You can keep this folder any where you want).
* For example : I have copied this folder from bi-server folder to similar location where the tomcat is installed .(from step 2 of this artical)
i.e.,  At [email protected]:/opt/jasperreports-server-cp-5.0.0# ls

apache-ant     common        installation.log  license.txt        properties.ini    scripts                  uninstall.dat
apache-tomcat  ctlscript.sh  java              pentaho-solutions  releaseNotes.txt  Third-Party-Notices.pdf
buildomatic    docs          licenses          postgresql         samples           uninstall

* You need to configure the the settings for postgresql in applicationContext-spring-security-jdbc.xml file
* location of this file is : pentaho-solutions/system/applicationContext-spring-security-jdbc.xml

<bean id=”dataSource”
>
<property name=”driverClassName” value=”org.postgresql.Driver” />
<property name=”url”
value=”jdbc:postgresql://localhost:5432/hibernate” />
<property name=”username” value=”hibuser” />
<property name=”password” value=”password” />
</bean>

* Next, you need to configure setting in : applicationContext-spring-security-hibernate.properties
* location of this file is : pentaho-solutions/system/applicationContext-spring-security-hibernate.properties

jdbc.driver=org.postgresql.Driver
jdbc.url=jdbc:postgresql://localhost:5432/hibernate
jdbc.username=hibuser
jdbc.password=password
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

8. Changes need to do in hibernate folder
Navigate to “hibernate” folder from “system” folder of same “pentaho-solutios” folder.
* You’ll find different .xml files for different databases.
* You need to touch
i) hibernate-settings.xml and
ii) postgresql.hibernate.cfg.xml          files.. i.e., you need to do some modifications in these two files.
Changes in :
i) hibernate-settings.xml file
Comment this line
<config-file>system/hibernate/hsql.hibernate.cfg.xml</config-file>

Enable this line
<config-file>system/hibernate/postgresql.hibernate.cfg.xml</config-file>

ii) postgresql.hibernate.cfg.xml

* You need not to do any modifications in this but you need to have an eye in this file.
if your postgresql port number is different than 5432 , just give your one and if you give the appropriate host if you use any host number .

9. Changes in context.xml file of META-INF folder of tomcat
* You need to modify the “context.xml” file located in the tomcat/webapps/pentaho/META-INF folder.
* In my example: It is located at

[email protected]:/opt/jasperreports-server-cp-5.0.0/apache-tomcat/webapps/pentaho/META-INF#

<Context path=”/pentaho” docbase=”webapps/pentaho/”>
<Resource name=”jdbc/Hibernate” auth=”Container” type=”javax.sql.DataSource”
factory=”org.apache.commons.dbcp.BasicDataSourceFactory” maxActive=”20″ maxIdle=”5″
maxWait=”10000″ username=”hibuser” password=”password”
driverClassName=”org.postgresql.Driver” url=”jdbc:postgresql//localhost:5432/hibernate”
validationQuery=”select count(*) from INFORMATION_SCHEMA.SYSTEM_SEQUENCES” />

<Resource name=”jdbc/Quartz” auth=”Container” type=”javax.sql.DataSource”
factory=”org.apache.commons.dbcp.BasicDataSourceFactory” maxActive=”20″ maxIdle=”5″
maxWait=”10000″ username=”pentaho_user” password=”password”
driverClassName=”org.postgresql.Driver” url=”jdbc:postgresql://localhost:5432/quartz”
validationQuery=”select count(*) from INFORMATION_SCHEMA.SYSTEM_SEQUENCES”/>
</Context>

NOTE: We deployed “pentaho” and “pentaho-style” folders in weapps folder of tomcat server.

10. Changes in web.xml file of WEB-INF folder of tomcat
You need to modify web.xml of WEB-INF folder of tomcat server. i.e,. tomcat/webapps/pentaho/WEB-INF/web.xml
* In my example the location of the file is :
[email protected]:/opt/jasperreports-server-cp-5.0.0/apache-tomcat/webapps/pentaho/WEB-INF#

<context-param>
<param-name>solution-path</param-name>
<param-value>/opt/jasperreports-server-cp-5.0.0/pentaho-solutions</param-value>
</context-param>

 NOTE: give the path for the “pentaho-solutios” b/w <param-value> and </param-value> tags

* You also need to check the port number & URL for the pentaho server in the same web.xml file.
<context-param>
<param-name>fully-qualified-server-url</param-name>
<param-value>http://localhost:9090/pentaho/</param-value>
</context-param>

NOTE: if you use some other port number for tomcat other than 8080 , you must specify the port number as shown above.

11.Tomcat server shutdown & startup
*  Go to the bin folder of tomcat server and shutdown the server if it already runs.
* Start the tomcat server.
* Commands :
Shutdown: ./shutdown.sh
Startup :   ./startup.sh

12. Type the pentaho server URL in any browser
* Go to the URL of any browser( Mozilla firefox is preferable as it is having firebug facility to track the errors if you get any)

Sorting and limit the bars on bar charts in Pentaho CDE without ORDER BY and limit functions in SQL Query ( Descending order)

Link

Hi Guys…!!!
This post tech you how you can make your bar chart dynamic..
You can limit the number of bars on bar charts with out using the “limit” function in your query as well you can also sort the bars in ascending or descending order with out using ORDER by clause  in SQL.

Some times you might have to deal with this type of functionality in your dashboard.
So here is a working example. Follow the steps…
Environment:
Pentaho BI server 4.8 stable with C-Tools(CDA,CDE,CDF 13.06) installed.
PostgreSQL
Aim : 
1) Creating a dashboard with two horizontal bar charts.
2) How to use single query result set for two charts
3) Order by the bar on the dashboard with out writing ORDER BY clause in SQL.
4) limit the number of bars on charts with out writing “LIMIT” clause in SQL

Suppose your result set is like below

Query Eg :
SELECT ColumnA, columnB,ColumnC from table_Name  GROUP BY ColumnA

Result set Assumption:
ColumnA          ColumnB       ColumnC
pentaho               45                     75
jasper                  23                     34
pdi                       90                     22
and assume there are 30 rows in the result set …

You are using single query to plot the two charts on dashboard using ColumnA,ColumnB & ColumnA,ColumnC.

When you use ORDER BY clause in the query, you can only either order by columnB or ColumnC but you can not order by with ColumnB and ColumnC.

* In CDE, there is a functionality called “Indexs”. Indexs for columns in pentaho CDE starts from 0,1,2 and etc.
* So ColumnA index is 0, ColumnB index is 1 and vice versa.

* Prepare your environment for the dashboard and have a look at the “Data sources” now.
* Click on “Output Options” and give index values as 0,1,2 by clicking “add” button multiple times.

How to get ColumnA, ColumnB on first chart ? (B’z you are using single query result set)
* Now click on the first chart component
* In the Advanced properties click on “Pre Execution”
* Write the below code to fetch ColumnA, ColumnB on first bar chart.

function f() {
this.chartDefinition.readers = [
{names:’category’, indexes: 0},
{names: ‘value’, indexes: 1},
{indexs: 2}
];
}

NOTE:
ColumnA=category and  is accessed with Index 0
ColumnB=value and is accessed with Index 1
index2 is written in the code b’z to ignore the value appending to the category showed on bars.

How to sort and limit the bars on first chart ?(B’z you are using single query result set)

* Click on the “Post Fetch” option from the Advanced properties.
* Write this code, this code will limit the number of bars on chart and sort the bars in descending order.
* In the code below “param_no_of_end_points” is the parameter created in the “Generic” section.
* And for the parameter create a select in the “Selects” section with “Text input” component.

function f1(cdaData) {
var categIndex = 0;
var valueIndex = 1;

var param_no_of_end_points = +Dashboards.getParameterValue(“param_no_of_end_points”);

if(isNaN(param_no_of_end_points))
{
param_no_of_end_points = 0;
}

var resultset = cdaData.resultset.slice();
var compareDesc = function(a, b)
{
return a === b ? 0 : a > b ? 1 : -1;
};
resultset.sort(
function(rowa, rowb)
{
return compareDesc(+rowa[valueIndex],+rowb[valueIndex]);
}
);

if(param_no_of_end_points > 0)
{
resultset.splice(0,resultset.length-param_no_of_end_points,0);
cdaData.resultset = resultset;
}
cdaData = {
metadata: cdaData.metadata,
resultset:  resultset
};
return cdaData;
}

Write the same code for the second chart but make sure to use different function names and Index value. In an application we can not write two functions with same name.

Save the the dashboard and see the preview.

Tech Tips in Penaho Server – publishing password setting for server – Disable the folder names in Browser panel in the Server

Hi guys..

The below tips are very useful in Pentaho Server for BI developers.
1) publishing password setting for server
You need to publish the reports or schema(s)[developed in PSW] once you done with developing. For this you need set the publishing password for Pentaho server.
Go to this location 
<location of Pentaho>biserver-ce-4.8.0-stable\biserver-ce\pentaho-solutions\system\publisher-config.xml and edit the “publisher-config.xml”  file.

Give your publish password b/w  these tags  <publisher-password> </publisher-password>

Example:
<publisher-password>password</publisher-password>    ( password can be any name that you wish to give)

Snapshot is a worth more than text. find the image below.

Save the file. stop the server and start the server.

2) Disable the folder names in Browser panel of Pentaho Server
* What ever the folder you create in Browser panel of pentaho server, it directly stores   under pentaho-soulutions
i.,e in this location
<Pentaho location>Pentaho\biserver-ce-4.8.0-stable\biserver-ce\pentaho-solutions
* You can disable all of your folders that comes with installation & the later created ones  which you don’t want to appear in the browser panel.
*   Inside every folder(pentaho default or the folders created by you) you can find “index.xml” file. You need to edit this file. You need to change visable tag as “false”.
Find the sanpshot.

You need not restart the server. Just you need to refresh the browser panel in the server.
You can observer the invisibility of the folder.

Date Input Controls/ Components in Pentaho CDE with a working example

Hello guys…!!!

In this post you will learn about how to create date input controls in CDE.
The dashboard images which I am going to show below are having lots of .css code. I’m not covering all the things but concentrating only on Date input controls in CDE.

My Environment :
BI Server: Pentaho 4.5
CTools: Not found the version numbers of  C-Tools(Unable to check them)– perhaps..! lesser than 13
Database : hsqldb (Comes along with Pentaho installation — A java based small db for servers like pentaho)
NOTE: Images are taken in this post after creating the dashboard, please find the yellow rectangular boxes to understand.

You need to work out @ 3 places in “Components” section.
1. Generic
2. Selects
3. Charts
Explained from step 1 to step 3
You need to work out  @ 1 places in “Data Sources” section. i.e, all in “Properties”
I’m not concentrating on Layout part for this example. So wherever the HtmlObject you find in this example replace them with your working HtmlObjects.

Step 1: Creating parameters
* Design your dashboard as per your requirement ( In the images you can find the sample designs).
 In the “Components” section:
1. Click on components
2. Click on Generic
3. Click on Date parameter
4. Go to properties give the name
eg: param_start_date
5. Click + symbol  per another date parameter
6. Go to properties give the name
eg: param_end_date

Find the  image

Step 2: Creating Date input Components
In the “Components” section
1. Click on Components
2. Click on Selects
3. Click on “Date input Component”
4. Go to Properties give name. eg: start_date in  my example
5. In the properties give HtmlObject. eg: start_date_select
* HtmlObject is the name of the column where you are putting
your dateinput control.
6. Give  Parameter.[It will appear once you try to type]
eg: In step 1, created parameters. So here give “param_start_date”
7. Give Listeners[click on it, you will find the list of Listeners. Click OK]
8. Repeat 3-7 for “end_date” Date input
component.

Step 3:
Find the steps in image.

 
HtmlObject is the place where you are putting your chart.

Step 4: Applying parameters for Chart & Query
            In the “DataSources”
Find the steps in the image
Find the sub sequent image for  Parameters applying for chart & Query.

do same as shown in images.

Step 5:
Save the dashboard and then Click on “Preview” button.
See the images below for sample out put with date input controls.
Preview of the dashboard with out any input controls selection

Preview of the dashboard after selecting date input controls.. find the images below one by one.

Find the image for observing whether the chart becomes dynamic or not with different date input controls.

That’s it.. You are done with date input controls on dashboard.
Thank you for reading this small post.

Jaspersoft CE v/s EE / Having Jaspersoft EE functionality in Jaspersoft CE

Jaspersoft CE versus EE / Having Jaspersoft EE functionality in Jaspersoft CE

 

Jaspersoft is world’s leading Open source BI software with more than 1.75 million download and usage. It comes in two variants, one is the community edition which is free and the other is the enterprise edition. Via this blog, we would try to understand the differences between the CE and EE. Also, we will make an attempt to understand and have Jaspersoft Enterprise Edition functionality in Jaspersoft Community Edition. Many a times, customers (esp startups and SMEs) dont have the budget or requirement to go for a full license, but they want full functionality which are present in EE, for them we have also discussed possible way outs as well.

 

a) Report Designer: Jaspersoft is known for its pixel perfect reports. This is created by iReport designer (free and open source). This tool helps in creation of complex reports with charts, graphs, tabular data, cross tabs, images etc. These reports can further be downloaded in different formats.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

b) Adhoc Report designer: Very beneficial for Business user, it gives a pivot kind of functionality, thus an end user can himself drag and drop the fields and create his own report on the fly. He can see this report as either a tabular data, or visualize it in different formats, save this and download this.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: In order to use adhoc reporting feature in Jaspersoft Community edition (CE), we can use a best of breed kind of solution. We can use Pentaho SAIKU plugin (its free), using this plugin for adhoc reporting, we can call it inside liferay and have adhoc reporting functionality in Jaspersoft as well.

 

c) Reporting Engine: Jasper reporting engine which is java based is again free and open source. It can fetch data from any kind of data source and provide picture perfect reports which can be seen, download (in different formats), printed.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

d) Dashboards: A dashboard can be a mix and match of reports, data visualizations, web APIs data, interactive parameters etc. Dashboard functionality is present only in the Jaspersoft EE

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing dashboard inside Jaspersoft Community Edition (Jaspersoft CE), we will have to go ahead with a best of breed solution. What we can do is for dashboards, we can use Pentaho CDE and CDF components. For representation of that, we can either use liferay or Alfresco.

Another alternative is we can call multiple instances of ireports inside liferay, thus creating a dashboard. For this a portlet has to be developed in liferay.

 

e) Interactive report viewing: This lets user to see the columns and perform functions like filter, arrange, sort etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

f) In-memory analysis: In memory basically helps in analyzing, seeing reports dashboards analysis etc on real-time and at a very high speed because it directly dumps all the information in its in-memory and doesn’t access db again and again for any requirement. This results in very high speed and throughput.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Again, to implement In-memory analytics in Jaspersoft Community edition, we will have to use a best of breed solution. We can go with the Pentaho SAIKU plugin (which is free of cost) and liferay usage for representation

 

g) Server Repository: Place to store reports, dashboards, views, mashups, analytics, user profiles etc.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

h) Report Scheduling / Report Bursting: Email scheduling of the reports (could be time or trigger based).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

i) Support: Jaspersoft is having multiple level of supports like standard support, premium support but it is only available to enterprise edition customers.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Jaspersoft CE customer, can either will entirely depend on community support or they can come to companies like us (Helical IT Solutions), which have expertise on Jaspersoft and can help out on all the issues.

 

 

j) Mobile Business Intelligence: – Native app supporting iOS and Android platform. Touch-based browser support for iPad. iOS and Android SDK for embedding BI in native mobile app.

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

k) Metadata Layer: Metadata basically means data about data content. Via metadata layer, we create another layer containing information about the database, hence thus implementing data level security.

 

Availability:    Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: For implementing metadata layer in Jaspersoft CE, what we can do is we can use OLAP server (which is present in CE – community edition) to design metadata layer along with implementing role and user based security.

 

l) User access to reports/dashboards and other things: This facility is again present in both the versions of Jaspersoft.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

m) Data Virtualization: This basically means integrating multiple data sources into a metadata view, and then doing BI work on it. This step reduces the work this involved in ETL.

 

Availability:  Jaspersoft CE: No

Jaspersoft EE: Yes

 

 Alternatives: The entire work of data virtualization can be done by writing ETL jobs and stored procedures. For ETL, Talend or Kettle either of the tool can be used.

n) Data Integration (ETL): ETL stands for extract transform and load. Extract means extracting data from different dbs (big data, columnary databases, graphical databases etc), web APIs etc. After extracting, transform the same according to the business rules and finally load it into the target system which could be a database, data warehouse, data mart etc. Jaspersoft has ETL tool by the name of Talend (also known as Jasper ETL).

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

o) Interactive Visualizations: This basically means very interactive HTML5 charts with animations, hover information, interactivity in terms of selection, zoom in zoom out, interactive legends etc.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: These kind of interactive visualizations are not present in Jaspersoft community edition. For enabling that, what can be done is we can design plugin designed like jcharts and openflash (for openflash plugins are already available). One of the very famous example is Pentaho Community edition having interactive charts by CCC components (community chart components). We can also use CCC and thus have best of breed solution.

 

p) OLAP Server: OLAP (online analytical processing) helps in analyzing large amount of data using querying, visualizations, multi lever analysis, slice and dice, filtering etc. OLAP helps users to understand multi-dimensional data from multiple-view point. It consists of mainly three functions – consolidation, drill down, slicing & dicing.

 

Availability: Jaspersoft CE: Yes

Jaspersoft EE: Yes

 

q) Multi-tenancy: This allows single instance support multiple customers, with each customer having his own userid password.

 

Availability: Jaspersoft CE: No

Jaspersoft EE: Yes

 

Alternatives: Multi-tenancy can be implemented in Jaspersoft Community Edition (CE) using Liferay portlet.

 

r) License: Jaspersoft CE has General public license whereas the license is having commercial license. Hence, if a client is Jaspersoft EE client, he does not need to open up his source code to the public, which is not the case with Jaspersoft CE clients.

Pentaho Community Dashboard (CDE) Basics – Creating a Simple Dashboard

Pentaho Community Dashboard Editor (CDE)
CTools Website – Community Tools

http://www.webdetails.pt/ctools.html

What is CDE ?
* CDE is one of the plugins for Pentaho BI Server, contributed and maintained by     Pentaho Partner webdetails.
* We create dashboards using this tool.
* Community Dashboard Editor (CDE) was born to simplify the creation, edition and      rendering processes of the CTools Dashboards.
* CDE is a very powerful and complete tool, combining front end with data sources and custom components in a seamless way.

Where you can get the plug-in in Pentaho Community Server ?
How to download the plug-in & what are the dependencies?

You can find the symbol “Pentaho Market place” on the menu bar..
Click on it you can see the Pentaho Marketplace editor as shown in below figure.
Find Community Dashboard Editor and Click on install.
As I have already installed it is showing as Up to Date.
Its generally a good practice to keep on updating the plugins with the latest version available in the market.
NOTE:
You must install the dependent plug-ins before you start working with CDE.

The dependencies for CDE are:
CDF(Community Dashboard Framework)
CDA(Community Data Access)
You must restart your server to take the effect of installation.

Where you can find the sample examples after installing?
* In the left side panel you can find plugin-samples folder.
* Expand it and then click on CDE
* In the Files you can find sample example CDE Sample Dashboard.
* Right Click on CDE_Sample Dashboard àThen click on Edit.
CDE has 3 major components
They are.
* Layout
* Componets
* Data Sources.CDE has developed based on MVC-2 architecture of Advanced Java Technologies.
* Layout – View
* Components – Controller
* Data sources – Model.
Find the images below to understanding the basic of CDE.

* Scroll down the dashboard. Find “About” on the left side and find the version number of CDE installed.

* Close the version window and Just click on Preview. I’ll let you know how to work out with all the components in CDE with a good working example.
* Now, just click on Preview. You can find the output of the dashboard as shown in below figures.

* Scroll down.

* Read the points that were in boxes. You will get the basic idea of CDE dash boarding.
Example:
Aim : To design a simple chart(on dashboard)
Environment:
* Pentaho BI Server community 4.8 stable version.
* CDA,CDF & CDE installed in the server from Market place.
Database: SampleData (It comes along with pentaho installation.. for this artical I’m not connecting to any external database.)
* This example was based upon CCC-Version1. The current Example which I’m going to explain is based upon CCC2-Version2.
* There are a lot of changes made from CCC-V1 to CCC-V2.
* Make sure your environment of CDE supports CCC-V2 for the example.

Step 1: Creating New CDE Dashboard
There are two ways to create a new CDE dashboard.
i) From the menu bar
ii) By clicking CDE icon
 Save your dashboard
 Click on Save -> Save your dashboard in your fav folder with your fav name.
 

After saving your dashboard  “Refresh your Repository” and then you can find the file as shown below figure.

Step 2:  Working with Layout, Componets and Data sources.
CDE is mainly works on scripting such as css, javascript.
Click on + sign.. (We are going to add Cascading Style Sheet code(css) code to our dashboard).
Resource type : css
External file
Resource type : css

Resource file : click on   ^  that is highlighted using arrow in the below image.

   * Give Styles2(do not give Styles2.css i.e, only give name but not extension).
   * It automatically cmes with .css extension and with $ and flower braces.
   * Save the css file externally to a folder as shown in below figure.
   * To see the Styles2.css appearing in the folder your file must contain some css code.
   * You must refresh your Repository to see the name of the file(Styles2.css) in the folder.
Giving Title to Dashboard:
*  CDE layout mainly works on Rows and Columns.
* Click on Add row symbol as shown in below figure.
 *  Give name of the Row and give back ground colour as shown in below figure.

* And give Corners: Round( it is below the back ground , not shown in the image-it is not visible here in the image)

 *  Now add Column(find ||) symbol on Layout Structure and click on it.

* Give all the necessary properties as shown in the below figure.
  Name: title
 HTML : <h1> Sales OverView YDT <h1> ( as show in figure at arrow symbol click on button.. You will be prompted to a new window there you have to write this HTML Code)
Font Size: 10
 See the preview:
The preview consists of only the title of the dashboard with its layout.
It is further going to be modified.

 Add your .css code here…

Css code
Body{
                background-color:#fffdf1;
}
h1{
                font-size:24px;
                color:#fff;
                margin-left:10px;
                margin-top:10px;
}
 Now see the preview.

By the time you get some idea on it.

Do as follows, I’m reducing the images now as you might get some idea..
Add another row -> Column->Html  as shown in figure.
For html give Name as title and write HTML code <h3>Sales Performance</h3>  in HTML editor
Add the following code to Styles.css to editor
h3{
    font-size:18px;
                font-weight:bold;
                color:#b68c58;
                margin-left:10px;
                margin-top:10px;
                margin-bottom:8px;
}
.salesTitle{
    color:#666;
                height:2px;
    margin-top:10px;
                margin-left:10px;
                margin-bottom:2px;
                width:939px;
}
Find the images for doing the above and see the preview again
 Add another column as shown in below figure

Give the following properties:

Name: sales_chart
Span size: 16
Now working with Data Sources and Query part:
  Click on Data Sources

·         Find SQL Queries in Left panel.
·         Click on sql over sqlJndi
·         In left panel give Properties
o   Name : get_sales_performance
o   Access Level : public (default)
o   Jndi: SampleData(We are working with pre defined database that comes along with pentaho software to develop this dashboard)
o   Query:
(
    SELECT
        ‘Profit’ as CATEGORY,
        ‘Measure’ as SERIES,
        SUM(ORDERFACT.TOTALPRICE-ORDERFACT.QUANTITYORDERED*PRODUCTS.BUYPRICE) AS MEASURE
    FROM
        ORDERFACT
    INNER JOIN PRODUCTS ON PRODUCTS.PRODUCTCODE = ORDERFACT.PRODUCTCODE
    WHERE
        YEAR_ID = 2004
)
UNION ALL
(
    SELECT
        ‘Profit’ as CATEGORY,
        ‘Target’ as SERIES,
        SUM(ORDERFACT.TOTALPRICE-ORDERFACT.QUANTITYORDERED*PRODUCTS.BUYPRICE) AS MEASURE
    FROM
        ORDERFACT
    INNER JOIN PRODUCTS ON PRODUCTS.PRODUCTCODE = ORDERFACT.PRODUCTCODE
    WHERE
        YEAR_ID = 2003
)
UNION ALL
(
    SELECT
        ‘Cost’ as CATEGORY,
        ‘Measure’ as SERIES,
        SUM(ORDERFACT.QUANTITYORDERED*PRODUCTS.BUYPRICE) AS MEASURE
    FROM
        ORDERFACT
    INNER JOIN PRODUCTS ON PRODUCTS.PRODUCTCODE = ORDERFACT.PRODUCTCODE
    WHERE
        YEAR_ID = 2004
)
UNION ALL
(
    SELECT
        ‘Cost’ as CATEGORY,
        ‘Target’ as SERIES,
        SUM(ORDERFACT.QUANTITYORDERED*PRODUCTS.BUYPRICE) AS MEASURE
    FROM
        ORDERFACT
    INNER JOIN PRODUCTS ON PRODUCTS.PRODUCTCODE = ORDERFACT.PRODUCTCODE
    WHERE
        YEAR_ID = 2003
)
UNION ALL
(
    SELECT
        ‘Revenue’ as CATEGORY,
        ‘Measure’ as SERIES,
        SUM(ORDERFACT.TOTALPRICE) AS MEASURE
    FROM
        ORDERFACT
    WHERE
        YEAR_ID = 2004
)
UNION ALL
(
    SELECT
        ‘Revenue’ as CATEGORY,
        ‘Target’ as SERIES,
        SUM(ORDERFACT.TOTALPRICE) AS MEASURE
    FROM
        ORDERFACT
    WHERE
        YEAR_ID = 2003
)
Working with Component
·         Click on Components
·         On the left panel click on Charts
·         In properties give the following
o   Name: sales_chart
o   Datasource: get_sales_performance
o   Width: 610
o   Height:140
o   HtmlObject : sales_chart
o   SeriesInRows : False
·         I will show you how to work with Advanced Properties in the upcoming posts on
CDE.
Now save your dashboard and Preview
The preview will look like as follows
That’s it.
This artical is for developing simple dashboard.
In my next article I’m going to make this dashboard dynamic with parameters and will make the dashboard better look and feel.
Thanks,
