IMS - DC  

Course	Introduction to IMS DC Application Programming
Level	Introductory
Overview	The participants will be introduced to the concepts and features of IMS – Transaction Manager. The course describes how application programs interact with IMS facilities. The participants will learn how to code and debug IMS TM programs written in COBOL. Lab sessions will help in reinforcing the concepts discussed during lectures.
Objective	On completing this course, participants will be able to - Understand the IMS functions and facilities. Describe the data communication functions of IMS Transaction Manager. Develop conversational programs.
Duration	Three (03) days: (09.30AM till 17.30AM)
Participant's Profile	Application programmers who will code and debug COBOL application programs for IMS Database and Transaction Manager.
Prerequisite	Basic knowledge of programming in COBOL. Working knowledge of TSO, ISPF and JCL.
Follow-on session	Mock or Live Project hands on is recommended after this course.
