Solution and Explanation

Understanding Database Terminology

1. Field in a Database Table

   • In a database, a field refers to a specific column in a table that holds a particular category of data.
   • For example, in a "Students" table, fields might include "Name," "Roll Number," and "Age."
   • Correct Answer: (D) Vertical column of the table

2. Why Other Options Are Incorrect?

   • (A) Name of the table:
     • The field is not the name of the table; the table itself is a collection of records and fields.
   • (B) Horizontal row of the table:
     • A row in a database is called a record, not a field. A record is a single entry in a table.
   • (C) Size of the table:
     • The field does not represent the table's size. Table size refers to the amount of data stored in it.

 Correct Answer: (D) Vertical column of the table

Key Concept

• Field = Column (Stores a specific type of data, e.g., "Student Name")
• Record = Row (Represents one complete data entry, e.g., details of one student)
• Table = Collection of Fields and Records
