My day job involves investigating and resolving performance problems, so I get to see a lot of bad stuff. Often, these problems have their roots in poor design. It is not surprising. but is nonetheless disappointing, that when I point this out I am told that the system is either delivered this way by the vendor, or it has already been built and it is too late to change.
In the last couple of years, I have worked on several data warehouse applications that have provided the inspiration for a new presentation that I am giving at the DOAG and UKOUG conferences this year.
The presentation and this series of related blogs have several objectives:
This particular blog post is an index to various topics within the presentation, that I have turned into separate blog postings.
In some of my examples, I have deliberately broken the data model in exactly the same way that I have seen it broken in real life. So, if you find yourself saying "nobody would actually do that!", let me assure you that they did!
