This software product, which allows users to save normal Java objects into a relational database and retrieve them without having to use SQL code. The authors note that this is not a simple process, and that the product, once used in an application, is going to stay there forever. Their approach is to start with the basics and then work toward the smaller details that apply to your specific project, so they even cover integration methods. They begin with configuration, then immediately build a simple application to get readers' appetites going. They describe the persistence life cycle, mapping, mapping with annotations, creating mappings with the product's XML files, using the session feature, conducting searches and queries, making advanced queries, filtering the results of searches, and taking on advanced features. They even include directions for upgrading from the previous version, something that should become standard in such texts. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com) Read Less
