IMS Database Manager and the Transaction Manager. It also covers data entry databases (DEDBs) and expedited message handling (EMH).
This training curriculum consists of three courses:
Audience
The primary audience includes users who want a basic understanding of the IMS Database (IMS DB) and IMS Transaction Manager (IMS TM) products. Additionally, data processing individuals
who work with an IMS system, whether Database (DB), Database/Data Communications (DB/DC), or Database Control Subsystem (DBCTL). Learners should be able to describe the
fundamentals of data processing, including the function of operating systems, access methods and Job Control Language (JCL). These skills can be obtained from on-the-job experience.
