For starters, in the Overview section it is presented the components of SQL Server.
I am working with SQL Server since is version 6.5. You can check in History section for the evolution of SQL Server.
I had a blog that is linked in Articles section.
I also created a FAQ (not really Frequently Asked Questions but Fast Answers for Questions) wich means direct answers for common questions.
Please check around and if you have any particular question where you couldn't find the answer, go to Contact me and drop me a message. I promise to answer to everyone as fast as I can.
You can also find me in Experts Exchange where I am one of the top SQL Server Experts and acting as a mentor when trying to help others with their SQL Server questions and issues.
Thank you for your visit and enjoy.
