Oracle Database 12c: PL/SQL II - Intermediate: Develop Program Units

Description

This textbook is intended for those who have already learned the basics of the Oracle PL/SQL database programming language and its syntax, and who are now ready to employ the language in the development of database applications. In particular, the focus of this textbook will be on the use of database-resident stored program units such as procedures, functions, packages and database triggers. New features introduced with the Oracle 12c release of the database are also explained and demonstrated.

About This Series

This textbook is part of the Sideris Oracle SQL Expert series, which in turn is one of the learning paths from the Sideris Oracle Database 12c: SQL & PL/SQL Programming curriculum.

Training Suggestions

This textbook may be used as one module within a Sideris textbook kit entitled Oracle Database 12c: PL/SQL Fundamentals (Levels I & II). When delivered in this format as an intensive instructor-led training (ILT) or live virtual training session at an accelerated pace, the suggested presentation length of the modules included in this kit is 5 days.

The sequence in which the modules should be considered is as follows:

Oracle Database 12c: PL/SQL I - Introduction
Oracle Database 12c: PL/SQL II - Intermediate: Develop Program Units

Prerequisites

Either of the Sideris textbooks Oracle Database 12c: SQL Fundamentals (Levels I & II) or Oracle Database 12c: SQL Complete Library (Levels I, II & III) are recommended prerequisites for this textbook.

Certification

This textbook considers subjects applicable to certification as both an Oracle PL/SQL Developer Certified Associate (OCA) and an Oracle Advanced PL/SQL Developer Certified Professional (OCP). The topics considered are included within "Exam 1Z0-144: Program With PL/SQL".

Objectives

This textbook explains how database-resident program units can be used as part of the overall database application architecture and the benefits realized by doing so. It then builds upon one's knowledge of database-resident program units and applies these to the development of PL/SQL packages. In a production environment most PL/SQL program units should be packaged, and these advanced database programming capabilities along with the benefits of using these are discussed. It concludes with extensive demonstrations on how a particular type of database-resident program unit known as a database trigger can be used as part of an advanced database application design.
