Course Description
The primary objective of this course is to provide an introduction to the PL/SQL database programming language, based upon the latest features available with the Oracle database. Syntax, structure and features of the language are discussed in the context of database applications and programming. This course equips students to develop database server-side PL/SQL program units within an Oracle database.
Course Topics:
Among the specific subjects discussed in this course are:
- Understanding application partitioning within a client/server or multi-tiered web-based systems architecture.
- Understanding the basic form and structure of program units stored within the database.
- Building and maintaining database-resident program units.
- Encapsulating program units within packages and taking advantage of accompanying advanced programming techniques such as cursor variables and cursor expressions.
- Handling intricate theoretical challenges, such as mutating tables.
- Building and maintaining DML-event and system-event database triggers, including advanced techniques using both simple triggers and compound triggers.
- Discuss the storage and execution model for database programs and how one can write efficient programs to maximize performance.
- Using system-supplied packages to extend the power of your SQL statements and PL/SQL applications.
