Relational databases are indisputably at the core of the modern enterprise. While modern programming languages, including JavaTM, provide an intuitive, object-oriented view of application-level business entities, the enterprise data underlying these entities is heavily relational in nature. Further, the main strength of the relational model—over earlier navigational models as well as over later OODB models—is that by design it is intrinsically agnostic to the programmatic manipulation and application-level view of the data that it serves up.
Many attempts have been made to bridge relational and object-oriented technologies, or to replace one with the other, but the gap between the two is one of the hard facts of enterprise computing today. It is this challenge—to provide a bridge between relational data and JavaTM objects—that Hibernate takes on through its object/relational mapping (ORM) approach. Hibernate meets this challenge in a very pragmatic, direct, and realistic way.
As Christian Bauer and Gavin King demonstrate in this book, the effective use of ORM technology in all but the simplest of enterprise environments requires understanding and configuring how the mediation between relational data and objects is performed. This demands that the developer be aware and knowledgeable both of the application and its data requirements, and of the SQL query language, relational storage structures, and the potential for optimization that relational technology offers.
Not only does Hibernate provide a full-function solution that meets these requirements head on, it is also a flexible and configurable architecture. Hibernate’s developers designed it with modularity, pluggability, extensibility, and user customization in mind. As a result, in the few years since its initial release,Hibernate has rapidly become one of the leading ORM technologies for enterprise developers—and deservedly so.
This book provides a comprehensive overview of Hibernate. It covers how to use its type mapping capabilities and facilities for modeling associations and inheritance; how to retrieve objects efficiently using the Hibernate query language; how to configure Hibernate for use in both managed and unmanaged environments; and how to use its tools. In addition, throughout the book the authors provide insight into the underlying issues of ORM and into the design choices behind Hibernate. These insights give the reader a deep understanding of the effective use of ORM as an enterprise technology.
Hibernate in Action is the definitive guide to using Hibernate and to object/relational mapping in enterprise computing today. Are you ready?
