What is the difference between online transaction processing and batch transaction processing?

An Batch processing system handles large amounts of data which processed on a routine schedule. An online processing system handles transactions in real time and provides the output instantly. In batch processing system fewer programming, hardware and training resources are required.

What is the difference between task and transaction in CICS?

Transaction. The difference between a transaction and a task is that several users can invoke a transaction but each user initiates his own task.

What are the differences between batch processing and online real time processing?

Real-time processing is data processing that occurs as the user enters in the data or a command. Batch processing involves the execution of jobs at the same time. The main difference is that administrators can postpone batch processes, while real-time processes must occur as soon as possible.

What is the difference between batch processing and interactive processing?

Comparison: Interactive session are usually used so that a person can become familiar with the computing environment and test their code before attempting a long production run as a batch job. Batch processing avoids idling the computing resources with minute-by-minute manual intervention and supervision.

What is CICS transaction?

A CICS transaction is a unit of processing initiated by a single request that may affect one or more objects. This processing is usually interactive (screen-oriented), but background transactions are possible.

What is difference between task and transaction?

Task. Represents a stage of a particular transaction. A transaction is considered complete only after all transaction tasks are complete.

What is batch and CICS?

With a batch program, you can repeat the processing, or continue it from the point of failure. In a CICS® application, input data is not prepared. The application user enters the data as needed while the application is running, and the data arrives in an unpredictable sequence.

What are the function in CICS?

CICS is called as Customer Information Control System. The main functionality of CICS is it acts as an interface between the Operating System and application programs. Acts as interface between operating system and application programs. Does the function of data communication and therefore handle data.

What is an example of batch processing?

Examples of batch processing are transactions of credit cards, generation of bills, processing of input and output in the operating system etc. Examples of real-time processing are bank ATM transactions, customer services, radar system, weather forecasts, temperature measurement etc.

What is batch processing used for?

Batch processing is a technique for automating and processing multiple transactions as a single group. Batch processing helps in handling tasks like payroll, end-of-month reconciliation, or settling trades overnight.
