Using Perl with the Informix Dynamic Server

Develop powerful applications for IDS

Daniel Hebert, Software Engineer, IBM
Daniel Hebert has his B.S. and graduate level experience in Computer Science from Rensselaer Polytechnic Institute. He has spent two years as a teaching assistant for a computer science department Perl course. Dan is a Software Engineer for IBM, primarily working with Informix Dynamic Server (IDS).

Summary:  This tutorial takes you through the process of setting up the Perl Database Interface (DBI) to work with the IBM® Informix® Dynamic Server (IDS). See examples of how to exercise a variety of DBI features and learn how to configure CPAN module installation, driver installation, script automation, data structures, pitfalls, and Perl interaction with IDS.

Final notes on running the DBI

It is true that you could spend weeks optimizing and rewriting a Perl program to squeeze out every last millisecond of performance. It's also true that Perl is an interpreted language and therefore is not going to run faster than a language which compiles to machine code. Try to keep these factors in perspective as they are beyond your control: DBI implementation, driver choice and implementation, network latency, machine capability, and the version of your database. Set clear and realistic goals for your project from the beginning to avoid inconsistent error handling techniques and poor modular design. If you are new to programming for IDS in Perl, it is a good idea to run basic tests of the DBI functions that you plan to use for your project. Keep in mind that different drivers implement things differently. IDS, Perl, the DBI, and specific drivers are still actively being developed to accommodate evolving technology.
