Form follows function

The required functionality determines the form of a data warehouse. This presentation aims to show how the form and architecture of a given data warehouse are determined by the challenges a company will meet when changing data in information. Solutions for those challenges shape the data warehouse, both technically and organizationally.

Please note that the presentation is in Dutch.

Anchor Modeling


Anchor Modeling is a new method of modeling a domain in a database. The method splits up all the attributes in their own table. This seems complex, but this actually simplifies maintenance. Furthermore, the method is flexible, quite resilient to change over time, does not need updates and is highly scalable.

These are good properties for a data warehouse model. In the article I explain how Anchor Modeling works and why you should at least take a look at it.
The article appeared in november 2009 in Database Magazine, Dutch magazine for database professionals. However, the magazine is now defunct and superseded by Business Information Magazine.
