Difference between Persistent and Non Persistent work variables?

The difference between “Persistent” and “Non-Persistent” work variables lies in how long they retain their values and where they are stored:

Persistent Work Variables

  1. Retain Values Across Sessions: These variables keep their values even after the program or system is restarted.
  2. Stored in Permanent Storage: They are usually stored in databases, files, or other non-volatile storage.

Example Use Cases:

  • User preferences stored in a database.
  • Session data saved for later retrieval.
  • Configuration settings that need to persist across application restarts.

Non-Persistent Work Variables

  1. Exist Only During Runtime: These variables lose their values once the application is closed or the system is restarted.
  2. Stored in Temporary Memory (RAM): They are usually stored in RAM and exist only during the execution of a program.

Example Use Cases:

  • Temporary counters or loop variables in a program.
  • Data processed in-memory for a specific task.
  • Variables holding user input that is not meant to be saved.
