Java Data Objects

-- First book introducing JDO, an enhancement for databases with improvements in application portability, performance and reliability. -- Complete coverage of JDOQL, a new query language, removing dependence on JDBC and SQL.

JDO, Java Data Objects is an API for transparent database access.

Programmers can write code in Java that transparently accesses the underlying datastore, without using database-specific code.

JDO is an object persistence technology and is complementary to JDBC.

JDO scores high on programmer convenience, because programmers do not need to learn SQL.

It gives you the ability to directly manipulate data stored in a database.

Most server-side developers have used JDBC to access databases.

JDO extends that by allowing programmers to work on the business solution without worrying about the infrastructure-level code to map between objects and databases.

This allows programmers to access Oracle, Sybase, and other implementations with greater ease.

There are a growing number of commercial applications and JDO products.

JDO is controversial in EJB forums, as some maintain JDO is superior to EJB's Entity Beans.

Many think JDO is a great tool, and more applications are to come.
