Solution
The correct answer to the question "Entities can be associated with one another in which of the following?" is Relationships.
Explanation
In the context of databases and data modeling, entities refer to objects or things in the real world that have a distinct existence. Relationships are associations between these entities. For example, in a database for a school, entities might include students and courses. The relationship could describe how students are enrolled in courses, indicating a connection between the two entities.
- Negative Marks: This term typically refers to a penalty in scoring where points are deducted for incorrect answers. In the context of this question, it does not apply.
- Entities: This term defines the items being described or stored but does not inherently discuss their connections with each other.
- Attributes: These are characteristics of entities that describe their properties but do not form associations with other entities.
- Identifiers: Identifiers are unique attributes used to distinguish each entity but, like attributes, do not create associations.
Thus, the primary concept of how entities interact in a structured way is through relationships.
