You are going to have be more explicit in your request. I have no idea in what context you are asking about compression.

Cool

Hi,

Thanks for your reply.
We have few tables in a database which are updated on a regular basis. So, i was asked to do row compression and page compression on these tables. I was wondering if there is any good article/document which can help me in this process.

Thank you!

Have you checked Books Online??
Before just going and enabling compression check the pre reqs and restrictions as there is an overhead and sometimes a performance impact.

Tables and indexes can be compressed when they are created by using the CREATE TABLE and CREATE INDEX statements. You should remember that Compression is not available for system tables. There are some consideration points which you have to consider before using page & row compression which you can easily find from here: http://msdn.microsoft.com/en-us/library/cc280449%28v=sql.100%29.aspx

The link also have the examples of Page & Row compression.
