I liked the blurb on the back:

“This title addresses all of the skills required to effectively design and develop complex applications, including planning, building and developing the application and coding defensively to prevent bugs.”

It suggests that it can bring you from the stage where you focus entirely on the code to the point where you can take in a whole project, make it all work and delight your customers. Mike Gunderloy has 25 years of commercial experience and so has a lot to say.

Introduction

PL/SQL is good for many things. It has a structured, Ada-like syntax and can have SQL statements seamlessly embedded in it. Although not compiled right down to machine code, it’s even fairly quick.

But one thing that most people initially have difficulty doing is displaying information on the screen. The first thing I did was to enter what I wanted into a temporary table and use SQL*Plus to select from it. This works well for reports at the like, but it doesn’t work at all if you want to display something independently of a transaction or halfway through a function.

## Introduction

What’s in here?

This document talks in non-technical terms about free software, what it means and why you should care about more than just the cost of your software.
