Expert Performance Indexing for SQL Server 2012 is a deep dive into perhaps the single-most important facet of good performance: indices, and how to best use them. The book begins in the shallow waters with explanations of the types of indices and how they are stored in databases. Moving deeper into the topic, and further into the book, you will look at the statistics that are accumulated both by indices and on indices. All of this will help you progress towards properly achieving your database performance goals.
What you'll learn from Expert Performance Indexing for SQL Server 2012 will help you understand what indices are doing in the database and what can be done to mitigate and improve their effects on performance. The final destination is a guided tour through a number of real-world scenarios and approaches that can be taken to investigate, mitigate, and improve the performance of your database.
