A DBMS that is based on relational model is called as RDBMS. Relation model is most
successful mode of all three models. Designed by E.F. Codd, relational model is based
on the theory of sets and relations of mathematics.
Relational model represents data in the form a table. A table is a two dimensional
array containing rows and columns. Each row contains data related to an entity such as a student. Each column contains the data related to a single attribute of the entity such as student name.
