DATA PROCESSING

 

              DATA PROCESSING

Today  I would like to discuss about data processing .First of all regarding this a question will arise in our mind that  data and information are same or different thing .What would be the answer lets see .

DATA is nothing but raw thing  which individual meaningless.

INFORMATION on the other hand meaningful or meaning based on the raw facts of data.

Lets take an example :COMPUTER this is a meaningful word which is nothing but an information  but I am telling  alphabet like C,O,M,P,U,T,E,R individually called data not information.When this alphabet combined and creates a meaningful words COMPUTER it is information.Now you are understand the difference between data and information.

DATA PROCESSING

It is performed by administrative organization for the business and is followed by systematic recording,arranging,filing,processing and reflecting the physical events occurring in the business.

Example like in an organization said Bank I want to disclose balance sheet to process that physical events I have to  collect so many information related to this means -recorded this data then arranging it properly after that filing it and processing it to get balance sheet.

In simple way data processing consists of

                                               1.INPUT

                                               2.PROCESSING

                                                3.OUTPUT

In any application we need to hold the data in various files that is master files and transaction files.

Master files known as permanent file and transaction file which is temporary in nature.

Lets take an example In a company named ABC Company thousand of employees are working

They are taking salary each month and for this company need to generate salary slip for every month now think about it what data is may changed and what data will be the permanent I am listing this below.

PERMANENT DATA	TEMPORARY DATA
EMPLOYEE NAME,ADDRESS,EMPLOYEE CODE,INCOME-TAX CODE E.T.C	EMPLOYEE WORKING DAYS,HOURS,OVERTIME,E.T.C

The above data is required to generate employee pay slip so from above which data need to set up in master file and which data  need to be store in transaction file it is cleared.We set all permanent data in master file and all temporary data in transaction file.
