What is the difference between a transient data and a temporary data in CICS?

Transien data and temporary data are both types of data in CICS, but they have different characteristics and purposes.

Transient Data:

• Transient data is temporary in nature and exists only for the duration of a CICS program execution.
• It is defined using the TRANSIENT attribute in CICS file definitions.
• Transient data is typically used for temporary storage or workspace during program execution.
• It is automatically deleted once the program completes or terminates.

Temporary Data:

• Temporary data, on the other hand, is also temporary but persists beyond the duration of a single program execution.
• It is usually stored in temporary storage queues (TSQs) or temporary data queues (TDQs).
• Temporary data is often used for exchanging data between multiple programs or transactions within a CICS environment.
• It must be explicitly deleted or purged when it is no longer needed.

In summary, transient data is short-lived and tied to a specific program execution, while temporary data can persist across program executions and is often used for inter-program communication.
