Data can be assembled giving to a hierarchy of categories, each progressively getting complex than previously. The data storage hierarchy consists of the levels of stored data: bits, bytes (characters), Fields, records, files, and databases. Computer hardware deals with bits and bytes In general we have to deal with characters, fields, records, files, and databases. For storing data, we must know its order how the data is stored. In this article, we will discuss the data storage hierarchy
Bit
It is the smallest figure in the data. Its value can either o or 1.
Character
It is also called a byte. It is formed using different bits. This is considered as the basic unit of human perception.
For example, it can be A,7, $,k anything
Field
The combination of different characters is called the field. This is a meaningful collection of different characters. The field is the smallest logical data entity that is behaved as a single unit in processing if the data.
Example customer-name, customer-city
Record
This is further the combination of different fields that may be interrelated. For example
Ram is any an employee of company ABC, its record in that company should be a place, phone, address, last name, city, a state in a collective order.
File
A file is made when numerous records are entered. So a file is a combination of the different records.
For example- a series of tests. It may include Gk test series, Hindi test series any of them
Database
The database is a large entity. In simple terms, it is the integration of various files that are related. The main purpose of the database is to eliminate the redundancy of the data.
E.G Complete information of the students of class 10th in database A.
