Foreword
One of the great plagues that falls upon Joe/Jane Java Developer is the complex task of mapping their beautifully designed objects onto the world of the Relational Database Management System (RDBMS). Some teams are able to use NoSQL solutions, but for the vast majority of developers, storing data in an RDBMS is a mandatory requirement (often because the database is shared among applications).
Hibernate is the lingua franca of this world, allowing developers to express CRUD operations and complex relationships in the familiar OO language that they know and love. However, as with any technology that attempts to map one paradigm to another (in this case, the object-relational impedance mismatch), there are corner cases and some core information that developers need to understand in order to lead sane lives in their day jobs!
Madhu’s book covers exactly this, immediately telling you why inheritance, identity, and relations/associations mismatches exist—and how to use Hibernate to smoothly deal with them. This book is vital reading for any Java developer, especially in the enterprise space. Madhu has had years of experience in getting this right, and I’ve seen that work firsthand—it’s great to see that finally distilled in this book. Get a copy today!
