Welcome !
Welcome to sqlCrunch! The idea behind sqlCrunch is simple; categorize and summarize links to SQL Server articles/blogs and present these links via a website. The benefits are twofold; portability and sharing. As a DBA, I'm constantly finding myself thinking about scripts or whitepapers that I used in the past, but can't remember where I saved it (if at all). By adding it to sqlCrunch, the link is saved for my future reference and is available for others to share as well.

In late 2008, I redesigned the pages of this site to mirror the chapters in my SQL Server 2008 Administration in Action book. Each chapter has a corresponding page on the site which supplements the chapter's content by linking the reader to additional information and best practices.

Please use the RSS feed to keep up to date with changes. I'm constantly adding new links and I welcome your feedback

Cheers,
Rod Colledge
