What is a BI analytical application ?

Posted by Dylan Wan on February 28, 2007

A BI analytical application provides the following four key components:

  1. Pre-built ETL to extract data from the operational tables in the transaction system  and load to the data warehouse
  2. Denormalized Star schema which is optimized for BI queries
  3. Best practice metric and calculation libraries that are created based on the data warehouse and operational sources.
  4. Pre-built graphics, reports, dashboards, and alerts that designed for specific roles and business processes

It is actually a very lengthly process to build an BI analytical application.  That is why people now buy the pre-built BI analytical applications.
