OLAP functionality is characterized by dynamic multi-dimensional analysis of consolidated enterprise data, supporting end user’s analytical and navigational activities. OLAP adds tremendous value to your BI applications by making analysis easier, faster and user-friendly for your business users.
OLAP schemas are used in order to enhance performance and provide drill-down functionality without much effort on the users’ side. The real power of OLAP is in the ability to drill down on a category to see more details. For example, you might drill down on a state to see details by city. An OLAP cube is a technology that stores data in an optimized way to provide quick response to queries by dimension and measure. Most cubes pre-aggregate measures by the different levels of categories in the dimensions to enable quick response time.
Pentaho uses Mondrian cube at the backend. Pentaho Schema workbench is a tool provided by Pentaho that enables the creation of OLAP Schema through a graphical interface. It allows a developer to create a pre-definied structure for faster reporting by aggregating the data and multithreading the process of retrieving the data from the database.
OLAP schemas enable a user to create analysis reports in Pentaho Analyser on the fly. Each OLAP schema is specifically created for a certain type of reporting, i.e., keeping in mind the kind of analysis that is going to be done on that data set.
