Data Processing

Any operation or set of Any operation or set of operations performed upon data, operations performed upon data, whether or not by automatic means, whether or not by automatic means, such as collection, recording, such as collection, recording, organization, storage, adaptation or organization, storage, adaptation or alteration to convert it into useful alteration to convert it into useful information. information.

Types of Data ProcessingTypes of Data Processing1. Manual Data Processing1. Manual Data Processing

This method of This method of data processingdata processing involves involves human intervention. The manual process of data human intervention. The manual process of data entry implies many opportunities for errors, such as entry implies many opportunities for errors, such as delays in data capture, as every single data field has delays in data capture, as every single data field has to be keyed in manually, a high amount of operator to be keyed in manually, a high amount of operator misprints or typos, high labor costs from the amount misprints or typos, high labor costs from the amount of manual labor required. Manual processing also of manual labor required. Manual processing also implies higher labor expenses in regards to spending implies higher labor expenses in regards to spending for equipment and supplies, rent, etc.for equipment and supplies, rent, etc.

2. Mechanical Data Processing

Different calculations and processing are performed using mechanical machines like calculators etc. The use of mechanical machines makes data processing easier and less time- consuming. The chances of errors also become far less than manual data processing.

3. Electronic Data Processing

EDP an infrequently used term for EDP an infrequently used term for what is today usually called "IS" (information services what is today usually called "IS" (information services or systems) or "MIS" (management information or systems) or "MIS" (management information services or systems), is the processing of services or systems), is the processing of datadata by a by a computer and its programs in an environment computer and its programs in an environment involving electronic communication. EDP evolved from involving electronic communication. EDP evolved from "DP" (data processing), a term that was created when "DP" (data processing), a term that was created when most computing input was physically put into the most computing input was physically put into the computer in punched card form or in ATM cards computer in punched card form or in ATM cards form and output as punched cards or paper reports.form and output as punched cards or paper reports.

Types of Data ProcessingTypes of Data Processing4. Real Time Processing

There is a continual input, process There is a continual input, process and output of data. Data has to be processed in a and output of data. Data has to be processed in a small stipulated time period (real time), otherwise it small stipulated time period (real time), otherwise it will create problems for the system. will create problems for the system.

For exampleFor example, when a bank customer withdraws a sum , when a bank customer withdraws a sum of money from his or her account it is vital that the of money from his or her account it is vital that the transaction be processed and the account balance transaction be processed and the account balance updated as soon as possible, allowing both the bank updated as soon as possible, allowing both the bank and customer to keep track of funds.and customer to keep track of funds.

Types of Data ProcessingTypes of Data Processing5. Batch Processing

In a batch processing group of transactions In a batch processing group of transactions collected over a period of time is collected, entered, collected over a period of time is collected, entered, processed and then the batch results are produced. processed and then the batch results are produced. Batch processing requires seperate programs for Batch processing requires seperate programs for input, process and output. It is an efficient way of input, process and output. It is an efficient way of processing high volume of data. processing high volume of data.

For exampleFor example: Payroll system, Examination system and : Payroll system, Examination system and billing system.billing system.
