Final answer:
option b,An EER model can be mapped to various types of logical data models, not just the relational data model.
Step-by-step explanation:
An entity relationship (EER) model can be mapped to a relational data model but to no other types of logical data models.
This statement is False. While it is true that an EER model can be mapped to a relational data model, it can also be mapped to other types of logical data models such as object-oriented data models and object-relational data models.
For example, in an EER model, you can represent a relationship between entities using inheritance, where one entity inherits properties from another entity. This type of relationship can be mapped to an object-oriented data model where objects can inherit properties and behavior from other objects.
The statement that an Entity Relationship (EER) model can be mapped to a relational data model but to no other types of logical data models is false. An EER model is a high-level data model that is used to define the data structure and relationship for a database system. While it is most commonly associated with relational databases, it can indeed be mapped to other types of logical data models, such as object-oriented models, XML database models, or other non-relational database models like NoSQL databases. This versatility allows the EER model to be useful in a variety of database management systems and not just restricted to the relational model.
