This class offers participants an extensive introduction to data server technology. The class covers the concepts of both relational and object relational databases and the powerful SQL programming language. Participants are taught to create and maintain database objects and to store, retrieve, and manipulate data. Students learn to retrieve data by using advanced techniques. They also learn to write SQL and SQL*Plus script files using the iSQL*Plus tool to generate report-like output. Demonstrations and hands-on practice reinforce the fundamental concepts.

Upon completion of this class, participants will be given extra lab time to prepare them to successfully pass the Oracle certification exam. Who should attend:

This course is valuable for programmers, application developers, database administrators, systems and network analysts, manager, Web developers and others who are or will be, programming with SQL.
