Chapter 23: Problem 2

Which account is designated as the owner of a relation? What privileges does the owner of a relation have?

Short Answer

Expert verified
The owner of a relation in a relational database is typically the account that creates the relation. As the owner, this account has all associated privileges, such as the ability to modify, delete, and update the relation, and control access for other users.

Step by step solution

01

Identify the Owner of a Relation

In a relational database, the account that creates the relation (whether it's a table, view, or other types of relations) is typically designated as the 'owner' of that relation. In other words, the user who creates the database or table in a RDMS (Relational Database Management System) is considered to be the owner of the relation.
02

Understand the Privileges of the Owner

As an owner of the relation, the user has all the privileges to perform any action on the relation. This includes actions like modification, deletion, updating, reading the data of the relation, controlling the accesses of other users, granting and revoking privileges to and from other users etc.
