The audience for which this book is intended, is quite literally, anyone who feels it is to his or her benefit to know something about SQL performance or about how to design tables and indexes effectively, as well as those having a direct responsibility for designing indexes, anyone coding SQL statements as queries or as part of application programs, and those who are responsible for maintaining the relational data and the relational environment. All will benefit to a varying degree if they feel some responsibility for the performance effects of what they are doing.
