ODB is an open source object-relational mapping (ORM) system for C++. It allows you to persist C++ objects to a relational database without having to deal with tables, columns, or SQL and without manually writing any of the mapping code.
Major new features in the 2.4.0 release:
- Support for bulk operations in Oracle and SQL Server. Bulk operations can be used to persist, update, or erase a range of objects using a single database statement execution which often translates to a significantly better performance.
- Ability to join and load one or more complete objects instead of, or in addition to, a subset of their data members with a single SELECT statement execution (object loading views).
- Support for specifying object and table join types in views (LEFT, RIGHT, FULL, INNER, or CROSS).
- Support for calling MySQL and SQL Server stored procedures.
- Support for defining persistent objects as instantiations of C++ class templates.
