Oracle Database 11g: PL/SQL Fundamentals II – Develop Program Units

Description:
The objective of this course is to equip students to develop database server-side PL/SQL program units within an Oracle database. Major subject areas to be explored and secondary objectives 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.
