From here you can read relevant white papers, check out sample chapters of the book for programmers who have had Database Administrator added to their job duties, join the User Forums where you can ask and answer questions and help to build the community of Reluctant Database Administrators, even join the Wiki where we can build a better knowledge of SQL Server.

SOME PEOPLE ARE natural-born database administrators (DBAs), some achieve DBA skills through training and mentoring, and some have DBA tasks thrust upon them. Whether you are a programmer who is now responsible for creating and maintaining a SQL Server database or someone who wants to understand the basics of database administration, this book is for you. Reluctant DBAs are those of us who haven’t had formal training in administering a database and are surviving on a combination of our wits, Books Online (BOL), and technical manuals. The biggest problem associated with BOL and technical manuals is the assumption of prior knowledge or experience. Though, truthfully, they are still regarded as the best source of information for SQL Server. Another great source of information is a community of fellow DBAs, for rarely is a probelm new when it's new to you.
