What is the difference between IMS DB and IMS DC?

IMS DB (Database) is a hierarchical database management system while IMS DC (Data Communications) is a transaction processing system.

IMS DB is used for storing and managing data in a hierarchical format, whereas IMS DC is used for processing online transactions in real-time.

IMS DB primarily focuses on data storage and retrieval, providing efficient access to vast amounts of data. On the other hand, IMS DC facilitates the communication between different components of a system for interactive processing.

In summary, IMS DB is used for database management while IMS DC is used for online transaction processing, making them essential components of the IMS category for handling data and transactions efficiently.
