An identifiable object like employee or department is an instance of which type?

• A. Entity
• B. Attribute
• C. Relationship
• D. Table

Answer: (A)

In data modeling, an identifiable object such as an employee or a department is an entity. An entity type defines a class of objects that can be identified and stored, while the actual objects you record are its instances (for example, a specific employee like John Smith or a specific department). Attributes describe the properties of the entity (such as EmployeeID, Name, HireDate). A relationship would describe how this entity connects to another (like which department an employee belongs to). A table is the database’s physical storage for the data, holding the rows that represent instances of the entity, not the type itself.
