In an ER diagram, the types of data models created in sequence are entities, attributes, relationships, and constraints. Entities represent the real-world objects, attributes describe the properties of entities, relationships establish connections between entities, and constraints define rules for the relationships or attributes. This sequence helps in organizing the structure and relationships of the data model effectively.

What are the characteristics of data model?
A data model specifies the rules and concepts on how to represent objects, their descriptions and how they relate. As such, the data model gives the definitions of the attributes and entities, specifies the datatypes of attributes and give relationships between entities.
