Data Inconsistency: Data inconsistency occurs when the same data appears in many tables in different forms. Which can deliver untrustworthy or meaningless information.

composite primary key: A composite primary key is also known as a composite key. A primary key for a table is formed by combining two or more columns.

Relationship: A relationship is a link or connection that exists between two or more tables. We don't need to insert the identical data in separate tables when we relate two tables. In DBMS, a connection is the way two or more data sets are linked, i.e., any association between two entity types is referred to as a relationship.
