What is Relational Model?

Relational Model is the most popular data model in DBMS and more scientic in nature. It is formed on the basis of the first-order predicate logic and describes a table as an n-ary relation.

The major aspects of this model are:

1. Data is stored and saved in tables called relations.

2. Relations can be normalized.

3. In normalized relations, values saved or stored are atomic values.

4. Each row in a relation has a unique value.

5. Each column in a relation has values from the same domain.
