"信息系统分析与设计案例2010-2.ppt：用例模型的建模与分析"

Information System Analysis and Design is a crucial process in the development of efficient and effective information systems. It involves the modeling of system functionalities through the use of use cases, which represent what the system does and the value it provides to users. Use case models help organize, classify, and document the information gathered during the requirements investigation phase. Use cases depict the interactions between users and the system, outlining the specific actions users take and the system's response in various scenarios. They are essential for understanding user requirements and ensuring that the system meets the needs and expectations of its stakeholders. In addition to use cases, use case diagrams, actors, and relationships are also important components of the analysis and design process. Use case diagrams visually show the relationships between different use cases and actors, helping to identify the system's functionality and the roles of various users. Furthermore, understanding the technical aspects and discussing the technology involved in the development of the information system is vital for ensuring the system is technically feasible and meets the desired requirements. This involves considering factors such as system architecture, data storage, security, and scalability. Overall, Information System Analysis and Design is a comprehensive process that involves analyzing user requirements, designing system functionalities through the use of use cases, and considering technical aspects to ensure the successful development of an information system. By following best practices in system analysis and design, organizations can create systems that are user-friendly, efficient, and meet the needs of their stakeholders.
