IBM Informix JDBC Driver

Version 3.70

Quick Start Guide

This guide describes a quick and easy way to install the product.

Product overview

The IBM Informix Java Database Connectivity (JDBC) Driver lets Java programmers access Informix databases from within Java applications or applets. Programmers can create client applications that use JDBC to connect to an Informix database server, retrieve data from the database, and handle errors. The Informix JDBC Driver can also be used for writing user-defined routines that are run on an Informix database server. The IBM Informix JDBC Driver is compatible with the JavaSoft JDBC specifications. The Informix JDBC Driver maps standard Java data types and Informix data types.

The following diagram provides an overview of the base architecture of Informix and the Informix JDBC Driver.
