Oracle Database 11g: Advanced PL/SQL

Beschreibung

In this course, students learn to use the advanced features of PL/SQL in order to design and tune PL/SQL to interface with the database and other applications in the most efficient manner. Using advanced features of program design, packages, cursors, extended interface methods, large objects, and collections, students learn to write powerful PL/SQL programs. Also learn programming efficiency, use of external C and Java routines, fine-grained access and safeguarding your code against SQL Injection attacks.
