Continuous Integration in Business Intelligence

or short term cost for long term gain

"... continuous integration (CI) implements continuous processes of applying quality control — small pieces of effort, applied frequently" - http://en.wikipedia.org/wiki/Continuous_integration

In my blog on Test-driven development I discuss the benefits of writing automated unit tests for business intelligence systems. If you are unfamiliar with the concept of unit tests, please read that blog first or one of the many articles on-line or on Wikipedia on the subject.

Test Driven Development in Business Intelligence

or why does nobody test their data!!!
Testing hall

It has been my experience that testing is always overlooked or poorly done within business intelligence environments. The consequence of this is inefficient designs, significant data integrity and validation issues, as well as defects within ETL and reporting scripts. This, in turn, often leads to expensive consultants who want to start the whole process from the start again. What I want to propose is the use of an agile quality assurance method, called Test-driven development, in the business intelligence context.
