Batch vs Real-time processing

hye....

now we are back......

with new information....

Batch vs Real-time processing..... 

Information systems are designed as a combination........

 of real-time and batch processing subsystems.....

Real-time processing is daily work......

 Also called online processing........

 it means that the database is updated as soon as a transaction is received.......

For example........ 

A sales order depletes inventory.......

 a stock sale updates the last close........

 a pledge adds to the fund raising balance........

 Transaction processing keeps business records up-to-date .....

the moment transactions are keyed into or transmitted ...

Batch processing is end of cycle..........

 A month-end report is batch processing as is printing payroll checks.......

There are many jobs that can be more economically processed at the end of a cycle........

 For example........

 the electronic transactions for telephone calls.......

 are stored in the computer until month end........

 when they are matched .....

against the customer tables for updating......

 with all the other telephone transactions at the same time.

that a little bit about it....

that all from us....

see ya....
