This report focuses on the development of a new information system, TSRIS, for the Allsports Club, a multisport club with thousands of members. The report begins with an introduction to the case study and identifies the need for a system to manage newsletter and advertiser details. It explores two software development methodologies: Agile and Prototyping, justifying their selection. Various data gathering techniques, including questionnaires, interviews, and group sessions, are discussed. The report outlines both functional and non-functional requirements for the system. Section B presents detailed diagrams, including a class diagram, use case diagrams with scenarios, an entity-relationship diagram, a data flow diagram, an activity diagram, and interface designs. These diagrams visually represent the system's structure, functionality, and data flow, providing a comprehensive overview of the proposed information system. The report concludes by summarizing the key aspects of the TSRIS project for the Allsports club.
