IMS/DB programming

This four-day course is designed, written and presented by Minerva Douglas, one of the UK's foremost IMS programming specialists. The course will provide the essential information that is required by programmers to enable them to use IMS to access Databases as effectively as possible. The course covers not only the facts about IMS database access, but also includes several practical exercises that allow attendees to work through various programs and learn the most structured and efficient use of IMS database calls.

On successful completion of this course you will be able to:

  • describe the basic components of IMS DB
  • understand and use IMS DB terminology
  • describe and explain the main facilities available in IMS DB
  • code and test a basic COBOL or PL/I program to access IMS databases.
