Kevin Hazzard did an outstanding job presenting to the Richmond SQL Server Users Group this evening on LINQ To SQL! I really like the ORM / code generation aspects of this new feature of the .Net Framework 3.5. Seeing it in action made me yearn (a little) for my application developer days. Kevin's VPC crashed a couple hours before his ...

Introduction: The World Series (1979) and Photography Willie ''Pops'' Stargell started my interest in photography (...a funny way to start a post on a SQL Server blog site, but bear with me). Pops Stargell led the 1979 Pittsburgh Pirates to win the World Series. He was the MVP that year as well. My Mom, in the only time I ever remember her ...

I have been struggling to find a way to describe the fundamentals of first normal form for my PASS presentation, and this came to mind last night.  SQL works in a very constructive way, meaning that if you have base values (commonly referred to as atomic, or scalar values) then you can build up the view that you want.  However, have ...

Oh no, you may be thinking, he has gone off the deep end.  Preparing for his talk on normalization at PASS this year he has finally cracked and said ''to heck with it, just denormalize...'' If you thought that, shame on you, and minus 10 points for you.  No, there is one very prominent place where most any database architect will tell ...
