This guide explains basic concepts behind application development with Oracle Database. It provides instructions for using the basic features of Oracle Database through the Structured Query Language (SQL), and Oracle Corporation's proprietary server-based procedural extension to the SQL database language, Procedural Language/Structured Query Language (PL/SQL).


This guide is intended for anyone who is interested in learning about Oracle Database application development, and is primarily an introduction to application development for developers who are new to Oracle.

Before using this guide, you should have a general understanding of relational database concepts and an understanding of the operating system environment that you will use to develop applications with Oracle Database.

As you become comfortable with technologies described in this guide, Oracle recommends that you consult other Oracle Database development guides, in particular the Oracle Database 2 Day + Application Express Developer's Guide, Oracle Database 2 Day + Java Developer's Guide, Oracle Database 2 Day + .NET Developer's Guide, and Oracle Database 2 Day + PHP Developer's Guide.
