Accessing IMS Databases from COBOL
The Accessing IMS Databases from COBOL course details the structure and use of an IMS/DB database. It gives examples of the DL/I data access language and shows how to use DL/I in COBOL programs to read and update IMS data. The concept of backup and recovery, particularly in the context of batch programming runs, is also explained.
COBOL Programmers who need to work with IMS databases.
The learner should have a solid knowledge of IMS database concepts and methods used to access an IMS database. This content can be obtained from the IMS Database course in the IMS curriculum.
- After completing this course, the student will be able to:
- Describe how a COBOL program access an IMS database
- Code a COBOL program to reference and manipulate IMS database data
- Describe how IMS Database recovery is performed following a COBOL program error
