Information Systems Development Project: Chemist Service Group

This project undertakes an object-oriented analysis of the Chemist Service Group's information systems development. It begins with requirements gathering, outlining the owner's perspective and identifying system users, including business and information system users. The domain analysis defines key concepts and scopes the system's functionalities. Behavioral modeling employs use case summaries and diagrams for product sales, inventory management, and customer ordering. Structural and dynamic modeling includes class diagrams and sequence diagrams to represent system components and interactions. The project covers essential aspects of systems analysis and design, providing a comprehensive overview of the Chemist Service Group's information system. The document is a comprehensive project report contributed by a student and is available on Desklib, a platform providing AI-based study tools.
