What Conceptual Models Are and Are Not
摘要
The term Conceptual Model (CM) means different things to different authors. This chapter explains what we mean by "conceptual model". In brief, a conceptual model is an abstraction that software designers use to document and convey essential characteristics of a software application before the application is developed. To avoid confusion with other software design abstractions, this chapter also explains how conceptual models differ from other design abstractions and practices.
