The Entity-Relationship Model is often referred to as a
semantic data model, because it more closely resembles real
world scenarios than, e.g., the relational model.
. In the ER model, we model the concept of "Instructors."
In the relational model we deal with names and phone
numbers.
. In the ER model, there is a distinction between entities
(objects) and relationships between such entities.
In the relational model, both concepts are represented by
relations.

Two types of ER?
There are two types of ER (Entity-Relationship) models: conceptual ER models, which focus on defining entities, attributes, and relationships in a domain, and logical ER models, which involve translating the conceptual ER model into a specific database schema design.

What structure is found on the rough ER that is not on the smooth ER?
Ribosomes are found on the rough ER, which are responsible for protein synthesis. Smooth ER does not have ribosomes.

What are two types of ER?
The two types of ER (Entity-Relationship) models commonly used in database design are the conceptual ER model, which describes the high-level concepts and relationships in a system, and the logical ER model, which defines the structure and constraints of the database in more detail.

What are the Names of the types of data models in an ER diagram in the proper sequence they should be created?
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.
