This project presents a comprehensive system analysis of the Allsports Sports Club, focusing on streamlining its services through software development. It begins with an introduction to system development methodologies, justifying the selection of the agile methodology due to its flexibility and iterative approach. The project details requirement gathering techniques, including interviews, questionnaires, and focus group sessions, and provides a sample questionnaire designed to elicit user feedback. Functional and non-functional requirements are defined, outlining the system's capabilities and operational characteristics. Data modeling is then explored, including class diagrams, use case diagrams, entity relationship diagrams, data flow diagrams, and activity diagrams to visually represent the system's structure and behavior. The project concludes with a discussion on interface design, emphasizing the importance of aesthetics and heuristic principles for enhancing user experience and interaction.
