Oracle Database 12c: PL/SQL I Introduction

Request more details:

Description:
This course introduces participants to Oracle database programming using the PL/SQL programming language. You will learn the syntax, structure and features of the language. This course will also lay the foundation to allow you to progress from introductory topics to advanced application design and programming and finally onto writing complex high-performance applications. PL/SQL may be considered as one of the key skill sets required for any Oracle professional, nearly as important as the SQL language itself.
Prerequisites:
Either of the courses Oracle Database 12c: SQL - Fundamentals (Levels I & II) or Oracle Database 12c: SQL Complete Library (Levels I, II & III) are recommended prerequisites for this course.
Audience:
The target audience for this course is all Oracle professionals. Among the specific groups for whom this textbook will be helpful are:

• Application designers and database developers
• Database administrators
• Web server administrators
Objectives:
This course begins with an explanation of the intent and usage of the PL/SQL programming language for database applications. Important reasons why one should incorporate PL/SQL modules within the application architecture right from the initial design and planning phase are presented. Next you will learn how to begin building executable PL/SQL program units. You learn about each of the major segments of a working program and how these interact with each other during program execution, including the important error or exception handling capabilities of the language. The final section goes beyond the basics and begins to explore advanced topics that will be useful later in the Oracle PL/SQL developer course. Techniques and features that allow modular and reusable programs to be developed are covered, increasing productivity and maintainability of database applications.
