There are tens of thousands of database professionals who could benefit from this book, and their number is growing rapidly worldwide. The market opportunity for this book lies in the explosive growth expected in the use of SQL (including XML and object-relational extensions) and the variety of uses being made by those using SQL. The most recent release of the SQL standard (SQL:2008) includes two sets of extensions: 1) support for object-relational databases and 2) support for XML. This set of commands has been greatly extended, and the new edition takes that into account. The XML extensions are entirely new to the 3e. A new chapter on basic relational concepts has been added to broaden the audience and make the book more complete in its own right.
