Oracle for the SQL Server DBA is a five-day course designed to provide SQL Server professionals with an in-depth understanding of the basic features of Oracle including object-orientation, partitioning and advanced Oracle features for the Internet.

This course is an introductory course for SQL Server DBA’s. The goal of this course is to cover the Oracle architecture and internal mechanisms such that the student is able to perform basic DBA tasks such as database creation, startup and shutdown, and database management. The course also covers Oracle networking basics and the Oracle utility programs.

exercises are used to demonstrate each feature and the student will gain first-hand experience in the key Oracle DBA concepts. Please note that this course is not taught as a preparatory course for the Oracle Certified Professional (OCP) program.

Book Details

This course is designed for the SQL Server professional who needs to understand the basic concepts and architecture of Oracle. This includes SQL Server developers, SQL Server DBAs, SQL Server web developers and any computer professional who needs to understand the architecture of an Oracle database. The student should understand basic relational database concepts such as SQL before enrolling in this training.

This course was designed by Donald K. Burleson, an acknowledged leader in Oracle database administration. Burleson was chosen by Oracle Press to write the authorized edition of Oracle High-Performance SQL tuning. Burleson Corporation instructors offer decades of real world DBA experience in Oracle features, and they will share their secrets in this intense Oracle new features training.

Learning Objectives

By the end of this course the student will have a functional understanding of the roles and duties involved in Oracle database administration and be able to perform basic Oracle DBA tasks.
