DATA | DATA ITEM | RECORD | FILE (DATA FILE)

 

"Data are made public as AN illustration of facts, concepts, or instruction in AN passing formalized manner or electronic machine."

Data is diagrammatic with the assistance of character like -alphabets(A-Z,a-z), digits(0-9) and special characters(=, ,-,*,,etc)...

FOR EXAMPLE:- The name of the student of a class. So, the name of the student is data.

take another example of data in our daily life experience if we want to find the volume of the room than we have to solve the formula:-

VOLUME  = LENGHT * BREADTH * HEIGHT 

So, in this formula the  LENGHT, BREADTH, HEIGHT are the data and the VOLUME is the information.

DATA ITEM(FIELD)

Data item (field) is a set of characters that are used together to represent specific data elements.

EXAMPLE:- CONSIDER THE EMPLOYEE FILE

So, in this example, the name of the employees is the data element. And the ID, the income of the employee is also also a data item (field).

RECORD

The record may be an assortment of connected knowledge things.

EXAMPLE:- a payroll record for an employee

A payroll record for an employee contains such data field as name, age, qualification, basic pay, DA, HRA, PF, etc.

FILE (DATA FILE)

The file is the allocation of related records. If we take an example of a payroll file of employees of a company.

So, this is the file of the collection of records.
