Oracle Database is a relational database that you can use to store, use, and modify data. Each vendor, such as Oracle, creates its JDBC implementation by implementing the interfaces of the standard java.

This guide shows you how to use a simple Java application to connect to Oracle Database and access and modify data within the database. This chapter introduces you to the Java application created in this guide, and to the tools you can use to develop the Java application in the following topics:.

JDBC is a database access protocol that enables you connect to a database and run SQL statements and queries on the database. However, JDBC is designed to allow vendors to supply drivers that offer the necessary specialization for a particular database. The classes and interfaces in these packages extend the JDBC standard. They allow you to access and modify Oracle data types and use Oracle performance extensions for JDBC with greater flexibility in a Java application.

Oracle Database Java Developer's Guide. It also includes support for JDK 6. It is platform-independent and does not require any additional Oracle software for client-side application development. It requires an Oracle client installation.

It does this by using native methods to call C-entry points. The oracle. This package consists primarily of classes that provide Java mappings to SQL data types and their support classes. Essentially, the classes act as Java wrappers for SQL data. The characters are converted to Java chars and, then, to bytes in the UCS-2 character set. Each of the oracle. Datum , a superclass that includes functions and features common to all the data types.

Some of the classes are for JDBC 2. In addition to data type classes, the oracle. The interfaces of the oracle.

These extensions provide access to Oracle SQL-format data. They also provide access to other Oracle-specific features, including Oracle performance enhancements. The key classes and interfaces of this package provide methods that support standard JDBC features and perform tasks such as:. The Java application tutorial in this guide uses Oracle JDeveloper 10 g release Oracle JDeveloper is an IDE with support for modeling, developing, debugging, optimizing, and deploying Java applications and Web services.

JDeveloper provides features for you to write and test Java programs that access the database with SQL statements embedded in Java programs.
