Are Common Language Runtime routines in SQL Server faster or slower than the equivalent T-SQL code? How would you go about testing the relative performance objectively? Solomon Rutzky creates a test framework to try to answer the question and comes up with some surprising results that you can check for yourself.

Write your database backup to multiple files. In addition to writing your database backup to one file you have the ability to write to multiple files at the same time and therefore split up the workload. The advantage to doing this is that the backup process can run using multiple threads and therefore finish faster as well as having much smaller files that can be moved across the network or copied to a CD or DVD.

Capturing performance monitor counters is of great value to understand how SQL Server is behaving at a macro level, that being how overall resources are being used within the engine. Without this data it is difficult to determine where the performance issues are occurring. Capturing the metrics has been traditionally from Performance Monitor either on an ad-hoc basis or setting up a log to capture the values on a predefined basis.

Microsoft Access is a very good database solution, but it has limits. While the portability of mdb and accdb files is convenient, there are advantages to moving to the less portable SQL Server solution. If you do have SQL Server, there's very little reason not to consider migrating your Access Databases. Not all custom-made Access applications easily lend themselves to a SQL Server solution so you'll need to do some analysis before choosing a migration path.

SQL Server Service Broker (SSBS) is a new architecture (introduced with SQL Server 2005 and enhanced further in SQL Server 2008 and later versions) that allows you to write asynchronous, decoupled, distributed, persistent, reliable, scalable and secure queuing/message-based applications within the database itself. Arshad Ali looks at how we can manage, monitor and troubleshoot Service Broker environments.

It is a fact of life: SQL Server databases change homes. They move from one instance to another, from one version to the next, from old servers to new ones. They move around as an organisation’s data grows, applications are enhanced or new versions of the database software are released.

There is a popular design for a database that requires a built-in audit-trail of amendments and additions, where data is never deleted, but superseded by a later version. Whilst this is conceptually simple, it has always made reporting the latest version of data complicated. Alex Kuznetsov joins the debate on the best way of doing this with an example using an indexed view and the filtered index.
