Astructural, or conceptual, model describes the structure of the objects that supports the business processes in an organization. During analysis, the structural model presents the logical organization of the objects without indicating how they are stored, created, or manipulated so that analysts can focus on the business, without being distracted by technical details. Later during design, the structural model is updated to reflect exactly how the objects will be stored in databases and files. This chapter describes class–responsibility–collaboration (CRC) cards, class diagrams, and object diagrams, which are used to create the structural model.
