Data Modeling Where I talk generally about how to build highly scalable, maintainable and performant databases

Databases Opinions, tips and trick specific to a specific database vendor
Grade of the Steel Putting databases to the test and doing extreme tuning.
Programming General programming tips and tricks. Typically related to high speed synchronisation techniques or algorithms.

There are some general themes that repeat themselves throughout this blog.

I have written quite a few blog posts that I hope you will find are coming together in a coherent theme of design guidelines. To make it easier to locate them, I have provided the index below.

Keys and how to handle them

In order to deliver clean and integrated data, the proper and high performance handlings of keys is crucial. I have blogged extensively about this here:

Warehouse Knowledge

Information about large databases and how they work.

Myth Busting

I like to put “common sense” recommendations from the database community to the test. Here are the posts I have written about this so far:
