The data compression feature in SQL Server 2008 helps compress the data inside a database, and it can help reduce the size of the database. Apart from the space savings, data compression provides another benefit: Because compressed data is stored in fewer pages, queries need to read fewer pages from the disk, thereby improving the performance of I/O intensive workloads. However, extra CPU resources are required on the database server to compress and decompress the data, while data is exchanged with the application. Therefore, it is important to understand the workload characteristics when deciding which tables to compress.

Many famous geeks work away at their programs without considering the wider implications of what they, and others, are doing. Richard Stallman isn't like that. Richard (rms) is one of the great brains behind Linux distros, as he wrote the GNU compilers and GNU debugger. He is driven by strong opinions about the nature of free software, and the restrictive nature of software copyright. We sent our intrepid reporter, Richard Morris, to find out if Richard Stallman really required journalists to read parts of the GNU philosophy before an interview, for "efficiency's sake".

Filestream allows us to store and manage unstructured data in SQL Server more easily. Initially, the accounts of FILESTREAM assumed prodigious powers of concentration and cognition, and we mortals all recoiled numbly. However, it became clear that we were missing out on some extraordinarily useful functionality, so we asked Jacob Sebastian to come up with a simple and clear-cut account of the FILESTREAM feature in SQL Server 2008. You'll agree he has managed the feat superbly.
