Ausführliche Beschreibung | Java Data Objects (JDO) is a standard way to access persistent data in
databases, using plain old Java objects (POJO) to represent persistent data.
The approach separates data manipulation (done by accessing Java data members
in the Java domain objects) from database manipulation (done by calling the
JDO interface methods). This separation of concerns leads to a high degree of
independence of the Java view of data from the database view of the data.
.
Interfaces are defined for the user's view of persistence:
- PersistenceManager: the component responsible for the life cycle of
persistent instances, Query factory, and Transaction access
- Query: the component responsible for querying the datastore and returning
persistent instances or values
- Transaction: the component responsible for initiating and completing
transactions
.
JDO is being developed as a Java Specification Request in the Java Community
Process. The original JDO 1.0 is JSR-12 http://www.jcp.org/en/jsr/detail?id=12
and the current JDO 2.0 is JSR-243 http://www.jcp.org/en/jsr/detail?id=243
