This book is a journey into Java data access performance tuning. From connection management, to batch updates, fetch sizes and concurrency control mechanisms, it unravels the inner workings of the most common Java data access frameworks.

The first part aims to reduce the gap between application developers and database administrators. For this reason, it covers both JDBC and the database fundamentals that are of paramount importance when reducing transaction response times.

The second part demonstrates how you can take advantage of JPA and Hibernate without compromising application performance.

The third part is dedicated to jOOQ and its powerful type-safe querying capabilities, like window functions or common table expressions.
