Which of these is also known as a virtual table?

Question

A) SCHEMA

B) DATABASE

C) JOIN

D) VIEW

Answer 1

A virtual table, often referred to as a VIEW in database terminology, is a logical representation of data from one or more tables. Unlike physical tables, a VIEW doesn't store data itself but dynamically retrieves and displays data from underlying tables based on defined queries. It allows users to manipulate and retrieve data without modifying the original tables. SCHEMA, DATABASE, and JOIN are not synonymous with a virtual table. Thus, the correct answer is D) VIEW.

Answer 3

A virtual table is commonly known as a VIEW in the context of databases.

A VIEW is a database object that presents data from one or more tables as a logical representation, similar to a table.

It allows users to retrieve and manipulate data without directly modifying the underlying tables.

A VIEW acts as a virtual table because it doesn't store any data itself; instead, it dynamically retrieves and displays data from the underlying tables based on the defined query or condition.

By using a VIEW, users can simplify complex queries, hide sensitive information, or create customized views of data to meet specific requirements.

SCHEMA, DATABASE, and JOIN are not synonymous with a virtual table.

A SCHEMA refers to the logical structure that organizes objects within a database.

A DATABASE is the overall container for storing data and related objects.

JOIN is an operation that combines rows from two or more tables based on a related column between them.

Therefore, the correct answer is D) VIEW, which is also known as a virtual table in the database terminology.
