3. History of BI4ALL Data Models  In the mid 90s numerous people noticed similarities in data models  Standard template models were tried by a few companies  Sean Kelly brought out Vertical Package Solutions (VPS)  VPS was sold to Sybase and that became Industry Warehouse Studio (IWS). Sold on Sybase IQ and Oracle  9/11 and the follow on recession caused Sybase to defocus on IWS. There was little revenue in data models  In 2006 Sean Kelly and Peter Nolan agree to create the “next generation” of data models based on experiences  2007 first sale closed to Key Work Consulting GmBH  Version 1.0 is “views in a text document”  Version 2.0 is “data model in an excel workbook”  Version 3.0 was a vast expansion of coverage  Version 4.0 is work in progress  There is still not much money in data models

4. How to Build Data Models in SeETL  This is a demonstration.

5. The Documentation Database  A “side by side” database. Can be a different RDBMS.  SQL Server is the only supported documentation database  The views are created as tables  Primary keys and RI constraints are added  Most databases will not allow keys or constraints to be created on views. In a DW you do not want RI constraints turned on anyway. So it is very hard to document directly from the production database.  This can be re-engineered into a data modelling tool  The data model is also loaded into the dictionary
