Tech Review

I got asked by someone to technically review their SQL Server 2005 book, so I'm betting that there will be lots of opportunties to learn a few things as I test code and work with the June CTP in the near future.

I also learned a few things with the September magazine, which focuses on High Availability in SQL Server. Database snapshots, which are incredibly easy to use to recover your db to a point in time, are one article. There's also mirroring, clustering, and partitioning in there.

The snapshot thing is interesting. It makes a copy of changed pages only, so queries against tables that haven't changed since the snapshot was created run against the original database. Not such a good idea for large tables to use this as a development environment. James Lukehoelter wrote the article and one of his suggestions was to combine mirroring on another server and then running a snapshot off of that. An interesting unique solution.
