Squeaky Surf Rental System: Business Modeling and System Design Report

This report presents a comprehensive business modeling and system design analysis of a board rental system. It begins with the identification of user stories, detailing customer interactions such as renting boards, paying deposits, and returning boards. The report then employs use case modeling to describe system functionalities, followed by class diagrams, state machine modeling, and system sequence diagrams to visually represent the system's structure and behavior. User interface design, including a login interface and a dashboard, is also provided. Finally, the report includes database modeling using an ERD to illustrate the system's data structure. The report references Connolly and Begg (2015) and Pressman (2017) to support the design methodologies.
