There are different basic types of processing; namely:
- Batch processing
- Real time processing
- Time sharing processing
- Demand processing
Batch processing
In Batch processing, data are gathered over a period of time and the batch of transactions is processed together. It employs sequentially processing technique which consists of processing the first record of the file sequence, then the second record in that order. Examples of batch systems includepayroll system, stock control, sales ledger etc.
Â
Advantages of batch processing
- It is economical and efficient for applications such as preparation of customer bills
- It saves time
Â
Disadvantage
- It may not be necessary or useful for all situations
Â
EVALUATION
- Explain computer processing modes.
- State the four modes of data processing
Real time Processing
With real time processing, data are processed one – by one within the same time – frame and the reports are produced quickly enough to influence decision in the ongoing process. It is appropriate for some banking applications, air line reservation system etc.
Â
Interactive Processing
The system displays questions and prompt messages on VDU,screen and the users provides appropriate response through the keyboard e.g Purchasing, inventory etc.
Â
On-Line Processing
This involves obtaining input data directly from the point where it is needed. Application areas include banking, Stock exchange etc.
Â
Transaction Processing
The transactions are processed randomly one by one as they supplied to the system e.g. real time banking.
Advantages of using computer for data Processing
- Increased accuracy.
- Efficient storage.
- Quick access to information.
- Ability to handle repetive tasks.
Â
GENERAL EVALUATION
- State the modes of computer processing
- Mention the application areas of each processing mode.
