SQLDict servers one purpose which is to brute force Microsoft SQL Server passwords. The easiest way to launch SQLDict is using the Backtrack navigation menu which launches the SQLDict.exe application using wine. The interface is easy to use as shown in the below example images.
If your daily driver is a Macbook or similar and you also manage a network that has Microsoft SQL Server running on it then it can be useful to login to those MSSQL Servers remotely. Even if its simply to view database layout or verify a service is running properly by actually connecting to it there is no doubt that having an easy method to connect to Microsoft SQL from OSX is beneficial. There are a bunch of JAVA based clients such as SQuirreL SQL Client or SQLRazor that are great applications but I personally use DBVisualizer or Navicat which are both described in more detail below.
