I need to encrypt my data within SQL Server and I plan on using the built-in encryption functionality in SQL Server 2005 and 2008. However, I'm looking at symmetric and asymmetric key algorithms and while I see information saying to use symmetric keys, I don't understand why. What's the difference between the two and why is a symmetric key algorithm preferred over the asymmetric key ones?

The Query Optimizer gets it right most of the time, but occasionally it chooses a plan that isn't the best possible. You can give the Query Optimiser a better idea by using Table, Join and Query hints. These come with a risk: Any choices you force on the Optimizer by using hints can turn out to be entirely wrong as the database changes with the addition of data over time. Grant Fritchey, in a chapter from his highly acclaimed book, explains further.

I have to deploy my SQL Server Analysis Services project to a test server then to a production server after testing is completed. For both of these deployments I need to provide an installation program. I am not allowed to access either of these servers. For my own testing I can deploy my project using Business Intelligence Development Studio (BIDS) and this works great. How can I create an installer that my IT team can use to perform the deployment?

The installation process for SQL Server 2008 has many different options. These options allow you more control over your SQL Server Instance configuration. Having this additional control allows you to set up your SQL Server 2008 instances out of the box with the appropriate configuration, like directory structure, accounts, etc. In this article I'll walk you through the SQL Server installation process.

Windows Azure and Azure Storage offers a new scalable and robust architecture that borrows much from the common feel of ASP.NET applications but brings plenty of new features as well. This paradigm shift from what has become traditional client-server architecture will offer new options to developers and headaches alike. While "the cloud" is not intended to be the answer for all applications and situations, it can only be a potential answer (another "tool" in the proverbial "tool belt") if you have at minimum a general understanding.
