The Architecture of the Oracle Database, SQL and PL/SQL
Oracle Tips by Burleson

The Oracle database is not a simple piece of software. Fortunately, becoming a good PL/SQL developer doesn’t require that you know everything about the internal structures of the database. Unfortunately, becoming a good PL/SQL developer requires that you understand a large part of the database architecture. This chapter is intended to provide you with a very high level perspective on what you need to know.

If you are already experienced with Oracle, SQL, and PL/SQL, you’ll probably want to browse this chapter and move on to Chapter 3. If you’re completely new to Oracle (either with or without previous development experience), make sure that you read this chapter before proceeding.

The Architecture Of The Oracle Database

Your knowledge of the database needs to cover the following basics:

  • Constraints

  • Indexing

  • Locking

  • Roles and privileges

  • Schemas

  • Sequences

  • SGA (system global area)

  • Snapshots

  • Synonyms

  • Tables and columns

  • Views

This list is by no means comprehensive. Your work as an application developer using Oracle and PL/SQL will continually expose you to new challenges; with hard work and dedication, you’ll meet those challenges head on.

This is an excerpt from the book "High Performance Oracle Database Automation" by Jonathan Ingram and Donald K. Burleson, Series Editor.
