Object-Relational Mapping
The Object-Relational Mapping tutorial walks though a basic metadata
mapping for an object to a relational database.
-
The Persistence Broker API
The Persistence Broker tutorial demonstrates how to use the PersistenceBroker API
which forms an object persistence kernel for OJB. While it is the lowest level API provided by
OJB it is also exceptionally easy to use.
-
The ODMG API
The ODMG API tutorial steps though using the ODMG 3.0 API provided by OJB. This is an
industry standard API designed for Object Databases.
-
The JDO API
JDO is a standard API for accessing persistent objects in Java. This tutorial steps through
how to use OJB's JDO plugin.
-
The Object Transaction Manager
The OTM is OJB's implementation of object level transactions. These are transactions
independent of the underlying relational database providing more efficient resource
utilisation and extremely felxible locking semantics.
-
OJB Queries
This document explains the usage of the query syntax.
-
Advanced O/R Mapping
