QxOrm
QxOrm is an Object Rational Mapping persistence framework for C++ with Qt. It supports cross compilation and is available for the platforms Windows 64/32 bit, Linux 64/32 bit and Mac OS.
The QxOrm simplifies the development of database access classes. The most common SQLs operations ( CRUD) must not be written manually, they will be generated by the framework. The developer have only to specify the meta objects. Data Access Objects DAOs have many methods to create, read, update or insert new entities. QxOrm uses a reflection mechanism to keep content of relations, properties, validators, primary keys and many other informations.
