Concept: A data model is made up of three main parts that together define how data is stored and handled.
Explanation:The first component is the structural part, which describes the data structures used to create a database, helping to represent the entities or objects being modelled.
The second component is the manipulative part, which defines the operations that can be performed on the data, such as inserting, retrieving, updating, and deleting records.
The third component is the integrity part, which sets the rules that keep the data accurate and consistent.
These three components work together to form a complete data model.
Answer:A data model has 3 components, so the correct option is B.
