Which data model represents data in the form of tables?

Concept

A data model defines the logical structure used to organize data and the relationships among data items.

In the relational model, data is represented as relations; a relation is commonly displayed as a table made of rows and columns.

Application

The question asks for the model whose basic representation is tabular. Rows represent tuples (records), while columns represent attributes (fields). This is the relational model.

Contrast

• The hierarchical model arranges records in a tree of parent–child relationships.

• The network model arranges records as a graph that can support multiple parent–child links.

• The object model stores information as objects containing attributes and methods.

Cross-check

A structure described using rows, columns, and relations matches the defining vocabulary of the relational model, so the result is Relational Model.
