An agile, efficient and much faster way of developing ETL jobs using advanced features like more control,visualization, reporting, plug & play modules, reusability etc.
Though there are many ETL tools available in the market, but using them also come with their own inherent problems, some of which are highlighted below,
Best Practices: Each and every developer does the ETL development according to his logic and his method of development; hence more often they forget to follow the best practices. These best practices are related to error handling, naming conventions, QA, QC etc.
Lack of standardization: Often not following the best practices on logging, error handling, naming conventions, documentation etc leads to lack of standardization between the different ETL jobs which have been developed amongst the different ETL developers.
Lack of control for end user: Generally in any ETL, an end user or IT administrator is often not able to see and monitor what exactly is happening. He has absolutely no control of the jobs, flags, status etc.,
