Question
Which of the following is NOT a basic element of all versions of the E-R model?
Solution
To determine which option is NOT a basic element of all versions of the E-R (Entity-Relationship) model, it would be necessary to consider the fundamental components of the E-R model, which typically include:
- Entities: These are objects or things in the real world that have an independent existence.
- Attributes: These are the properties or characteristics of entities.
- Relationships: These show how entities are related to each other.
Common options that might be presented could include abstract symbols, roles, or any advanced concepts that are not foundational.
To answer your question definitively, I'd need to know the specific options you are evaluating. However, if one of the options doesn’t pertain to entities, attributes, or relationships, that would likely be the correct answer.
If you provide the options, I would be able to identify which is NOT a basic element of the E-R model.
