Question

Arrange the following in hierarchy to create a DBMS:

FIELD, DATA, FILE, RECORD

Answer 1

To correctly arrange the components in a hierarchy for creating a Database Management System (DBMS), you should understand the basic building blocks and how they are structured from the smallest to the largest units. Here's the hierarchy from the smallest unit to the largest:

1. Data: This is the most basic unit, consisting of the smallest individual items of information (like numbers, characters, or bits).

2. Field: A field (or column) represents a single type of data stored in a database, such as a name or age. Each field holds one item of data for each record.

3. Record: A record (or row) is a group of fields that collectively represent a single entity or instance within a table, such as all the information pertaining to one customer.

4. File: In database terminology, a file typically corresponds to a table or a collection of records. It organizes multiple records into a single unit or structure within the database.

Therefore, the correct hierarchical order for creating elements within a DBMS, starting from the smallest unit of data and moving to the larger structures, is:

Data → Field → Record → File
