What is data model?

Answer 1

A data model is a conceptual representation of how data is organized, stored, and accessed in a database or information system. It provides a structure for defining and organizing the logical relationships between different data elements and entities. Data models can vary in complexity, and they can be represented using various notations, such as entity-relationship diagrams or UML diagrams. They are used to facilitate communication and understanding among stakeholders involved in the design and development of a database or information system.
