Here, we can use the terms "domain class diagram" and "design class diagram" for the conceptual information model and the information design model made in the form of UML class diagrams. The main difference between analysis class diagrams and design class diagram is the analysis phase focus on designing a class diagram without concerning about the implementation detail. A conceptual model can illustrate the water cycle, where evaporation and transpiration lead to the formation of clouds and then to precipitation in the form of rain, sleet, or snow.
