Solution

Adding rules to data in a relational database typically means adding Constraints. Constraints are used to limit the type of data that can go into a table. This ensures the accuracy and reliability of the data in the table. Constraints can be column level or table level.

Primary Key and Foreign Key are types of constraints. A Primary Key uniquely identifies each record in a table and must contain unique values. A Foreign Key is a column or a set of columns in one table, that is used to establish a link between the data in two tables.

Permission is not a rule added to the data but rather a security measure to control the access to the database.
