This course provides a comprehensive presentation of the major features and capabilities of IMS/DB (Batch). IMS/DB programming concepts and coding techniques are explained. Detailed coding examples are provided to reinforce the class materials and hands–on workshop problems.

This course is intended for a Systems Analyst/Applications Programmer or an Applications Programmer who will be responsible for the development of IMS/DB application programs.

Upon successful completion of this course, the student will be able to:

• Understand the environment that supports the execution of IMS/DB application programs
• Understand the purpose and program structure associated with an IMS/DB application program
• Understand the use and coding requirements for SSAs, Boolean SSAs, Command Codes and Secondary Indexes
• Complete numerous in–class exercises and hands–on programming (COBOL) workshops
