Introduction to Oracle 11g Programming Course

In this course, students will learn how to create, retrieve, and manipulate objects in Oracle 11g SQL. Students will also be introduced to Oracle 10g database features and tools. The Oracle 11g release has greatly enhanced the features and functionality of PL/SQL. Students will learn the fundamentals of the PL/SQL programming language. Students will write stored procedures, functions, packages, and triggers, and implement complex business rules in Oracle. Students will learn programming, management, and security issues of working with PL/SQL program units. Programming topics will include the built-in packages that come with Oracle, the creation of triggers, and stored procedure features.

Audience: Database application developers

Familiarity with relational database concepts as well as a solid understanding of 3GL programming are required.
