Online Magazine Management System Software Engineering Report

This report presents a Software Engineering analysis of an online magazine management system. It includes a use case diagram depicting the system's functionalities, such as making subscriptions and publishing documents. The report expands on selected use cases, detailing the actors, triggers, purpose, and summary of each process. Activity diagrams illustrate the workflows for publishing documents and managing subscriptions, while Level 2 Data Flow Diagrams (DFDs) map the data flow within these processes, including entities, processes, and data stores. The appendix provides additional diagrams and extended use cases to enhance the understanding of the system's design and functionality. The analysis covers the payment process and document publishing, providing a comprehensive overview of the system's architecture and operation.
