  Introduction to Java in the Database

Introduction

Adaptive Server Anywhere is a runtime environment for Java. This means that Java classes can be executed in the database server. Building a runtime environment for Java classes into the database server provides powerful ways of adding programming logic to a database.

Java in the database offers the following:

• You can reuse Java components in the different layers of your application—client, middle-tier, or server—and use them wherever makes the most sense to you. Adaptive Server Anywhere becomes a platform for distributed computing.

• Java is a more powerful language than stored procedures for building logic into the database.

• Java can be used in the database without jeopardizing the integrity, security, and robustness of the database.

Separately-licensable component 

Java in the database is a separately licensable component and must be ordered before you can install it. To order this component, see the card in your SQL Anywhere Studio package or see http://www.sybase.com/detail?id=1015780.

The SQLJ standard 

Java in the database is based on the SQLJ Part 1 proposed standard. SQLJ Part 1 provides specifications for calling Java static methods as SQL stored procedures and user-defined functions.
