You might be able to tell that TempDB has been on my mind a bit lately. Unfortunately, TempDB is not the name of some person or social thing, it’s about work and the place where SQL Server stores its temporary stuff (and mine or any other SQL programmer’s stuff.)
In this webcast you get a pretty good idea of what you should do and look out for in your (if you have a SQL Server) Database environment. (And, nowadays, who doesn’t have a „database environment“? … comeone, sure you do… or?)
