changelog

Ujorm is an quick and easy-to-use ORM solution for Java with a small footprint. Some of its features are type safe parameters in queries, a memory overloading protection cache and relation mapping by Java code rather through proxy objects or entity states.

Why a new ORM mapping?

* framework has a type safe query language which allows the java compiler find a syntax error similar like a 4GL language
* never more a LazyInitialization exception though a lazy initialization is supported
* no confusing proxy business objects
* no list properties are supported but a special object called UjoIterator is designed for a collection. The UjoIterator provides a toList() method for example
* easy to configure the ORM model by java source code, optionally by annotations and a XML file
* great performance, e.g. multi SELECT is eight times faster in comparison with Hibernate
* small size of JAR file and no more library dependencies
