Custom BI solution vs Package solution:

These days there is a lot of talk about use of package solution like Jaros as a BI solution. This will save lots of effort needed in the analysis and design phase. Jaros provides BI solution on top of Oracle ERP. It uses the metadata of Oracle ERP in creating the metadata for ETL. Currently it supports 14 modules in ERP. Normally, a big organization will have lot of customization on ERP. This requires good deal of efforts in customizing the package to business. Jaros is not a feasible solution that use more than 14 supported modules and also for large ERPs with heavy customization.
When we develop a BI solution we will have the liberty to choose the ingredients of our BI solution. We can have the state-of-the-art tools in each phase of the Data Warehousing. Every problem in this world is unique. Each requires a unique way of addressing it. Ideally it suggested to deal it specifically rather than generalizing it and using a general solution available in the market.
