What is the difference between a domain model class diagram and an ERD?

What is difference between analysis model and design model?
– Analysis model represents the external, higher level or logical view of the system (the more abstract conceptual view, black box model). – Design model represents the internal, lower level or physical view (the more concrete implementation view, white box model).
What is difference between design and analysis?
“Analysis” is a broad term, best qualified, as in requirements analysis (an investigation of the requirements) or object analysis (an investigation of the domain objects). Design emphasizes a conceptual solution that fulfills the requirements, rather than its implementation.

What is an entity in an ER diagram?
An entity is a real-world object. ER diagram represents the entities and their associations. For example, a hospital database has separate tables for patients, doctors, and medical reports. Each of them is an entity. In the ER diagram, a rectangle signifies an entity. An entity that depends on another entity is a weak entity.
What does a dashed line mean in an ER diagram?
The designer can draw a dashed line under an attribute in order to denote a foreign key in the ER diagram. A diamond shape or a rhombus represents the association among entities. Moreover, the relationship with a weak entity is called a weak relationship. Furthermore, a double lined rhombus denotes a weak relationship.
What does a rectangle represent in a class diagram?
