<vendor> MVCSoft is pleased to announce the professional edition of its Persistence Manager, available immediately. The MVCSoft Persistence Manager is an implementation of container-managed persistence as defined in the EJB 2.0 specification (proposed final draft 2). This version supports JBoss, the open-source J2EE application server. It implements CMP entity objects, relationships, and the EJB 2.0 query language. It provides a Swing-based GUI mapping tool, online help, and an ant task. It is able to map relationships with foreign keys or a relationship table, and provides important performance features such as load-on-demand, fault groups, and pre-loaded data based on finder queries. The MVCSoft Persistence Manager comes with full source code to every component, from the runtime library to the code generator to the mapping tool. You can redistribute the runtime component with no royalty costs or additional licenses. The MVCSoft Persistence Manager requires a version of JBoss with local interfaces. These are supported in JBoss 2.4 and above. Here are just some of the features that the Persistence Manager supports: * Swing-based mapping GUI. * Flexible O/R mapping in terms of representing relationships with foreign keys or relationship tables. * The ability to load data in user-defined groups to minimize database I/O. * Tuned updates. * Five different types of database locking: timestamp (optimistic), sequence field (optimistic), field comparison (optimistic), "select...for update" syntax (pessimistic), and complete deferral to the database. * Complete support for the EJB 2.0 Query Language. It will preload data during a query to solve the "n+1" database access issue, and you can tune the set of data that will be loaded based on the query. * Complete support for referential integrity rules, and for one-one, one-many, and many-many uni- and bi-directional relationships. Our license is per-developer, and set low enough ($199) to make it accessible to everyone. Sell an unlimited number of your "predeployed" EJB components with no runtime fees.
