What are the characteristics of interactive data processing?

Answer 1

1. Batch Processingo Batch programming allows an end-user or supervisor to execute a series of programs without human intervention. These programs are scheduled to start a computer system by using an automated routine created to let programs run in batches. Batch programming allows for the sequential processing of data. Batch processing can update records after the last record in the database is reached. Real Time Processingo Real time processing is a dynamic data processing ability which allows instant updates of database records due to a transaction being performed on a record. Real time processing keeps databases updated with instant access to the latest record changes through query, inquiry or exception report. On-Line Processingo On-Line processing allows for the processing of information on the system at the same time through two or more systems. For example, a banking institution has an on-line system. Tellers can service different accounts at the same time, check balances and perform inquiries. The different between on-line processing and real-time processing is that online processing provides only query and payment services and not the reporting function. Distributed Data Processingo Distributed processing is the dissemination of centralized databases and programs across various networks and servers which may not be located in the same work area, building or even geographical region. Regardless of where centralized applications are in the grand scheme of the network, distributed data processing allows for applications to be accessed by end users.
