This preface introduces you to the Oracle Database Java Developer's Guide, discussing the intended audience, structure, and conventions of this document. A list of related Oracle documents is also provided.
Java has emerged as the object-oriented programming language of choice. It provides platform independence and automated storage management techniques. It enables you to create applications and applets. Oracle Database provides support for developing and deploying Java applications.
This preface contains the following topics:
The Oracle Database Java Developer's Guide is intended for both Java and non-Java developers. For PL/SQL developers who are not familiar with Java programming, this manual provides a brief overview of Java and object-oriented concepts. For both Java and PL/SQL developers, this manual discusses the following:
How Java and Database concepts merge
How to develop, load, and run Java stored procedures
The Oracle Java virtual machine (JVM)
Database concepts for managing Java objects in the database
Oracle Database and Java security policies
To use this document, you need knowledge of Oracle Database, SQL, and PL/SQL. Prior knowledge of Java and object-oriented programming can be helpful.
