Database Access

Enterprise Java applications often move data back and forth between Java objects and relational databases. There are several ways to do this, ranging from manually coded SQL to sophisticated object-relational mapping (ORM) solutions such as Hibernate.

Java Database Connectivity (JDBC), which has existed from the first public version of the core Java language, has evolved significantly over the last 10 years. In its current version, 4.0, which will be packaged with Java Standard Edition 6.0,it shows significant improvements in design and provides a richer API, with focus on ease of development and improvement in productivity.
