Oracle 10g PL/SQL Programming - ORA509

PL/SQL is the Oracle embedded procedural database language, allowing developers and administrators to write scripts, stored procedures, functions, packages, and database triggers which run in the optimized environment of the Oracle Database server. The Oracle10g release has greatly enhanced the features and functionality of PL/SQL. This advanced course helps PL/SQL programmers take advantage of language features, advanced techniques, and packages and facilities provided by Oracle to develop and tune efficient and effective PL/SQL subprograms. 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.
