Controlling Jobs and Sessions Interactive data processing can be defined as a dialog between user and computer. Data is entered via a keyboard terminal. The computer immediately answers by running processes and/or displaying prompts, messages, and other types of information. A period of time spent processing data interactively is called a session. Batch data processing occurs when data is entered into the system in bulk from a batch entry device, such as a spooled disk. When data is entered and processed in batch, the activity is called a job.
