Many BI vendors, particularly front-end solution-vendors, try to convince you that you do not need a data warehouse as a building or feeding mechanism for their front-end tool. This is a very bad advice and it will cost you dearly in the long run.
These vendors mostly offer you to put together a quick proto-type for one single source of your ERP-system (e.g. sales) and they build a simple data-feed and trick you with a nice looking front-end result of your data and push you in a sale. However, as soon you start trying to update the system on a daily basis or try to integrate other data sources you will find how difficult if not even impossible this is.
The secret sauce for your successful business intelligence system is not a sexy looking front-end, it is the work-horse of a data warehouse, which guarantees clean data, proper hierarchies, integration with a variety of data sources and much more. Only data warehouses make it possible to compare, consolidate and analyze data from a broad base of source data.
After your data is loaded into a data warehouse, it will not be changed except for correction of errors. This is the only way for you to guarantee that the front-end tools later show one version of the truth for answering business questions from a variety of users. I have seen this too often that different users came up with different results from the same source data only because everyone had applied different business rules when the data was extracted, so whom to believe?
There is a new business intelligence tool on the market which combines an easy to use data warehouse, a fantastic front-end tool for reporting and analytics and pre-defined interfaces (Quick Cubes) for a variety of ERP systems and business applications like sale reporting etc. It is called BDA - Business Data Analysis - and is very inexpensive and unbelievably fast to install (in just a few days).
Visit the website of BDA and register for a Webinar to learn more about how to build a data warehouse and business intelligence system.
For a limited period of time, BDA also offers a free Proof Of Concept (POC) with your own data, so Click Here to go to their website, click on the registration for the Webinar, ask for a one-on-one Webinar, followed by a POC.
