IMS concepts

During this course participants become familiar with the general principles of the IMS system. Both the database system (IMS/DB) and the transaction manager (IMS/TM) are treated.

The main objective of this course is to offer -in particularly for the database part- an insight into the link between physical structures and its logical view of applications. An overview of the possibilities of such applications is given.

The description of the TP-monitor gives an insight into message processing in the IMS system. The different ways of building an application (conversational versus non-conversational) are also treated.


No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please let us know.
