Before you start

Learn what to expect from this tutorial, and the technical environment.

Introduction

Although IDS is one of the best general purpose and online transaction processing (OLTP) databases out there, you may need to extend its function set. IDS provides a very open interface for doing so: UDRs. UDRs can be developed in Java, making portability a non-issue, helping you benefit from your existing Java knowledge and letting you reuse libraries and components already available in your applications.

Objectives

In this tutorial, you first discover the fundamentals then directly jump to a real-life example. You also call your Java UDR from an Informix 4GL application. You then see how you can include this example into Eclipse, the famous development environment. Finally, you study the deployment strategy to use your UDR in production.

Prerequisites

It is assumed that you have development experience with IDS. No Java or Informix 4GL background is required.

System requirements

In this tutorial,you will use the following:

  • IDS V10.0.TC4
  • J2SE Development Kit (JDK) V5.0 (update 6)
  • and Eclipse V3.2 RC7

This example uses Windows XP, but the examples are easily portable to Linux or any other UNIX system.
