Part I
Basic PL/SQL Concepts
In this part . . .
Part I includes two chapters to get you started with PL/SQL. Because you need to understand something about relational databases to be a good PL/SQL programmer, Chapter 1 provides a quick overview of the most important concepts. It also reviews some database terminology and explains some of the differences between SQL and PL/SQL. For those with very little programming experience, Chapter 1 includes a very brief explanation of the basic structure and syntax of PL/SQL and explains where it is most useful.
Chapter 2 describes the total PL/SQL environment and explains how to set up this environment so you can begin writing code. You discover how to set up a database, connect to it, and access the Oracle sample schemas that you can use to practice.
