Another Disaster (Almost)
Andy had a semi-disaster similar to the one he wrote about last year. Interesting to see the kinds of problems that happen to other people. This article raises some interesting points that are outside the scope of basic disaster recovery, looking at how/when to move databases to a different server and how to reduce the server load dynamically.

For most DBAs, normalization is an understood concept, a bread and butter bit of knowledge. However, it is not at all unusual to review a database design by a development group for an OLTP (OnLine Transaction Processing) environment and find that the schema chosen is anything but properly normalized. This article by Brian Kelley will give you the core knowledge to data model.

Robert shows you how he did it here.

USE Sales GO CREATE STATISTICS CustomerStats1 ON dbo.Customer (CustomerKey, EmailAddress) WITH INCREMENTAL = OFFThe dbo.Customer table is partitioned. How are statistics created? See possible answers
