SQL Clearly Explained

by Jan L. Harrington

Written with both beginner and intermediate database developers in mind, this clear, concise guide teaches readers about the relationships between the distribution of data in a database and the way in which queries of various types are processed.

The book teaches not only SQL syntax but also explains the proper structure of SQL queries and how a query affects the SQL processor and system performance.
