What does it mean when a domain class model does not answer a question?
If you find that the model does not provide answers to some useful questions then it indicates that some information is missing from the model.
What is domain model?
A domain model is a graphical representation of real-world ideas or flow, and not software or databases. Domain models show entities or things, and how they are related. Several diagrams and tools can be used to model various domains.

Can you translate a model into a real system?
Yes , you may be able to translate these models into real systems, but you cannot design a good system without having a clear understanding of how the real world (in this case, Wizard Accounting) works. The models we have shown are important, but you cannot get hung up on developing the perfect model. The key is understanding reality and creating ...
Can a domain model show the relationship between two employees?
A domain model can show the relationship between the two and define that relationship. A job is 'held by' an employee. One job can actually be held by more than one employee. Take note of the number 1 and the asterisk on the line. This means that for one job, there can be any number of employees holding that job.
What is a class diagram?

Is it better to use a class diagram or a class diagram?
The answer is: Instead of modeling every entity and its relationships on a single class diagram, it is better to use multiple class diagrams. Dividing a system into multiple class diagrams makes the system easier to understand, especially if each diagram is a graphical representation of a specific part of the system.
What is domain model?
The domain model is a sketch of the elementary entities of the system and the relationships between them. It is platform independent (not intended for any specific programming language) and attributes do not have data types. When creating a domain model, we base it on the client's requirements.
What is the last relationship in a use case diagram?
The last relationship, we'll mention here, is generalization. In terms of implementation, it represents inheritance. One entity inherits the properties and behavior from another entity. We've already seen this kind of relationship in the use case diagram.
In short
Domain model and a conceptual mean different things to different people. There is no universal authoritative definition of these terms.
Some more arguments
A domain model describes the elements of the real word for which a software shall provide a solution.
