[edit] Features
- OJB is open source (open source code).
- Is also lightweight and easy to use, because to implement a persistence layer, one must simply configure two files (see section below)
- Easy to integrate into an existing application because it does not generate code.
- Allows the use of different patterns of persistence: owner (PersistenceBroker API), JDO and Object Data Management Group (ODMG).
[edit] Configuration
At least two files are required to configure OJB:
- OJB.properties
- repository.xml
[edit] Allocation
For mapping a 1-1 relationship, for example, you have two tables: person and account. In this case, a person has an account and vice versa.
