What are IMS?
An Integrated Management System (IMS) combines all aspects of an organisation’s systems, processes and Standards into one smart system. A successful IMS cuts the unnecessary hassle and work of multiple management systems. For example, instead of holding audits for each Standard, you will only need to hold one.
Which is better IMS DB or DB2?
DB2 optimizes queries internally whereas IMS programmers construct access paths to data. This additional requirement will cause DB2 to consume more CPU. But, of course, that additional CPU brings with it the enormous benefit of database optimization and better ad hoc query support.
What is IMS DB DC?
This example of an IMS™ DB/DC system definition includes definitions for data communication, system configuration, databases, and application programs. A sample IMS DB/DC environment is the basis for this example of an IMS DB/DC system definition. An overview of the IMS system is followed by system details and macros.
