Latest version: 2.0
Added 2005-05-23
Convenience framework for applications that use JDBC that allows you to externalize your SQL statements into individual files, and allows declarative mapping from tables to objects.
O/R Broker is another object-relational tool, except it differs from most in that it allows use of constructors, setter methods, and direct field access, as well as JavaBean properties. The developer maintains all control over SQL, allowing fine-grained performance.
O/R Broker serves solely as a broker between the database and an object model. It allows object encapsulation, and doesn't require an object model to follow strict JavaBean rules, which can be useful.
One of the design goals for O/R Broker was simplicity. There are are only 4 public classes, and an XML Schema file for validation of the configuration. The only dependency is Java 1.4 or higher, and there is optional support for Velocity and FreeMarker for dynamic SQL generation.
Features include:
- Inheritance mapping
- SQL statements externalized in individual text files
