The methodology helps identify the areas of slow performance by looking at the problem from two directions called Waits and Queues.

Data space can be a concern in many situations as more and more data is being stored in your systems. Designing your schema to take this into account is important for a DBA and Steve Jones takes a look at how design decisions can be used to solve a business problem.
Keeping track of the performance of your SQL Servers requires metrics.

Setting up replication can be fairly easy, but deviating from the follow-the-wizard approach can be tricky. New author Claudia Rego brings us a primer on setting up transactional replication without requiring an initial snapshot.
Steve Jones talks about the ne value of the new certification program from Microsoft.
Part III of the article series illustrates how to partition an existing table with data into four different file groups.
