Conceptual model: refers to a model that abstracts and summarizes the essential characteristics of things with words. For example, the literal description of eukaryotic cell structure, the explanation of material and energy changes during photosynthesis, and the explanation model of Darwin's natural selection theory.
Mathematical model: a mathematical form used to describe a system or its characteristics. Such as: temperature (PH value), cell cycle duration of different cells and other effects on enzyme activity.
Extended data:
Conceptual model modeling process
1, use the concept list or noun phrase to find out the candidate concepts in the problem domain.
2. Draw the concept into the conceptual model diagram.
3. Add an association to the concept.
4. Add attributes to the concept.
Conceptual model model design
1, the conceptual model does not depend on specific biological systems, it is a conceptual structure that purely reflects information needs.
2. Modeling is based on the results of requirements analysis, and the data is often abstract. Common data abstraction methods are "aggregation" and "generalization".
3. E-R method is commonly used in conceptual model design. The ER diagram of the design and the corresponding explanation can be used as the stage result.
