What are Java® data objects?

Java® programming is a computer software language that uses modules and functions to handle data. Java® (JDO) data objects are Java® module, which is used to transform data from database to Java® software programming. These data objects are used by developers to change the data that come from the database. It is a standard method used by Java® programs to access and change data. These elements are divided into components that map specific functional data types. Some examples of data objects include people, addresses and phone numbers. Each data object has a specific purpose for the application. It is a simple method of data distribution into individual components. The JDO module contains a specific application programming interface (API) for handling data of SVATABASE. This API allows Java® programmers to access data and change changes.

There are many tutorials available on the Internet to explain how Java® data objects are available. These tutorials usually include a peakADY and developer forums that provide assistance to programmers. Most developers can learn how to use JDO in a few days. It is a relatively simple API that can learn for an experienced Java® programmer.

Access architecture used by Java® data objects is known as object relational mapping. This is a computer programming method of data mapping into objects. Each object has control of the data contained in the object. It also has relationships with other objects based on predefined rules.

There are several alternatives to Java® data objects. These include complex Enterprise Java® Beans (EJB) and Simple Java® Database CONTERTIVITY (JDBC). These technologies can be used instead of Java® data objects and each comes with its own advantages and disadvantages. One advantage for Java® data objects is that it provides standard APIs to question multiple database types,that never changes regardless of the database used.

One of the problems with JDO is its inability to handle complicated features and updates of the database. The JDO module supports standard access methods, but the complex connects and distributed updates become problematic. If the software program requires comprehensive data manipulation, the JDO module may not be a suitable option.
