Overview of Oracle Extensions

Oracle's extensions to the JDBC standard include Java packages and interfaces that let you access and manipulate Oracle datatypes and use Oracle performance extensions. Compared to standard JDBC, the extensions offer you greater flexibility in how you can manipulate the data. This chapter presents an overview of the packages and classes included in Oracle's extensions to standard JDBC. It also describes some of the key support features of the extensions.

This chapter includes these topics:

• Introduction to Oracle Extensions

• Support Features of the Oracle Extensions

• Oracle JDBC Packages and Classes

• Oracle Type Extensions

  Note: This chapter focuses on type extensions, as opposed to performance extensions, which are discussed in detail in Chapter 13, "Performance Extensions".
