because Scheme model Model building for the information world is a layer of abstraction from the real world to the information world, and a language for communication between users and database designers. Therefore, on the one hand, the conceptual model should have strong semantic expression ability, and be able to easily and directly express various semantic knowledge in applications. On the other hand, it should also be simple, clear, and easy for users to understand. Because the conceptual model is very simple in this iteration process, it was originally planned to PASS the specific analysis, but the conceptual model is really very important, it is a cornerstone of OOD. In addition to use cases, it should be said that the conceptual model is another subjective artifact in the OO development process.

However, different people may refine different conceptual models when studying the same scene, so this is a process that is quite affected by subjective cognition. However, the quality of the conceptual model is crucial to the impact of the whole system, because the so-called object-oriented starts from here.

Generally speaking, the process of building conceptual models has little to do with programmers. The people who are suitable for this activity should be the domain experts with deeper qualifications, or even the customer representatives who are familiar with their own business processes.
