Yet Another SQL Strategy for Versioned Data

There is a popular design for a database that requires a built-in audit-trail of amendments and additions, where data is never deleted, but superseded by a later version.

Alex Kuznetsov joins the debate on the best way of doing this with an example using an indexed view and the filtered index.  Read more...

A Tale of Identifiers

Identifiers aren't locators, and they aren't pointers or links either. They are a logical concept in a relational database, and, unlike the more traditional methods of accessing data, don't derive from the way that data gets stored. Identifiers uniquely identify members of the set, and it should be possible to validate and verify them. Celko somehow involves watches and taxi cabs to illustrate the point.  Read more...
