"If you walk into a room full of DBAs or DB developers and you feel like having the same kind of fun as setting fire to a dry hayfield, just ask this question: “What’s a better design, using natural keys or artificial keys?” Satisfaction guaranteed.
When I started to study database design, this was one of the first hot controversies I encountered. If you Google the phrase “natural vs. artificial keys,” you’ll come up with more than 150 million results, including endless debates, numerous articles, blog posts with passionate replies, long theoretical and practical arguments, and even the occasional profanity."

Today I want to share with you a true story that happened to me last week. Although a bit off-topic, you might find it 'amusing', useful and a real time saver in case you ever need to do the same thing.
When I bought my desktop PC last year, I purchased an SSD drive to be used as the system drive (C:\). At the time, the prices of SSD devices was pretty steep so although I had some doubts, I convinced myself that a 40GB drive should be more than enough to accommodate everything I need. Big mistake #1. As it turned out, only the I-tunes backups of my iPhone which (for some reason) can be placed only on C:\ took 16GB... Add to that my SQL Server installation, office and other essentials. Most of these applications, even when installed to a different drive, still place a lot of stuff on the system drive so soon I found myself struggling for space and using every trick in the book to free up as much space as possible on C:\ just to be able to work.

I've recently encountered some confusion regarding one of the new components of SQL Server 2012, the SQL Server Data Tools AKA SSDT. From the questions in the MSDN SQL Server forum which I moderate, I realized that the distinction between SQL Server Management Studio (SSMS) and SSDT is not clear enough to many. I have to agree that Microsoft did leave some space for confusion and a lot of duplicate functionality in both tools so let's try to clear up a bit of this confusion.

Yesterday, at our 118th Israeli SQL Server User Group Meeting, Adi Cohn delivered a session on common performance pitfalls. One of the issues he mentioned is something every DBA and database designer should be aware of. Many applications use overly large size limit for their variable data types. The reasoning in many cases is simply "Why not?" If you have a variable size column and you made the choice to use one of the VAR data types anyway, why limit the size? Even if you expect to have up to 300 characters in the 'comments' column for example, what is wrong with defining it as 3,000? it's just metadata, right? Wrong...

An interesting discussion came up lately on the MVP private forums regarding index rebuilds,recompilation and statistics updates. Although the debate spanned too many aspects for me to cover here in this short post, I think that one important point should be emphasized as it might be making you do redundant work or even worse - unknowingly degrade the performance of your workload.
