Explanation

The relational database model uses attributes and tuples to contain and organize information. The relational database model is the most widely used model. It presents information in the form of tables. A relational database is composed of a two-dimensional table and each table contains unique rows, columns, and cells. Each cell contains only one data value that represents a specific attribute value within a given tuple. These data entities are linked by a relationship that forms the base for organization of data.
