The authors offer a pragmatic, consistent comparison of each leading framework - both proprietary and open source. Writing for IT managers, architects, administrators, developers, and testers, the authors address a broad spectrum of issues, ranging from coding complexity & flexibility to scalability & licensing. In addition, they demonstrate each framework side by side, via a common example application. With their guidance, you'll learn how to define your persistence requirements, choose the most appropriate solutions, and build systems that maximize both performance and value.Coverage includes:- Taking an end-to-end application architecture view of persistence;- Understanding business drivers, IT requirements, and implementation issues;- Driving your persistence architecture via functional, nonfunctional, and domain requirements;- Modeling persistence domains;- Mapping domain models to relational databases;- Building a yardstick for comparing persistence frameworks and APIs;- Selecting the right persistence technologies for your applications;- Comparing JDBC, Apache iBATIS, Hibernate Core, Apache OpenJPA, and pureQuery.The companion web site includes sample code that implements the common example used throughout the technology evaluation chapters, 5-9.
