This project focuses on the application of UML diagrams in system analysis and design. It includes an Entity Relationship Diagram, a Class Diagram, a State Machine Diagram, and a Sequence Diagram. Each diagram is presented with a figure and a brief description. The project also includes a bibliography citing relevant research papers on UML diagrams and their applications. The diagrams likely illustrate the structure, behavior, and interactions within a system, providing a visual representation of the system's components and processes. The bibliography supports the project by referencing academic sources related to UML diagrams and their usage in software development and system analysis. This assignment is designed to demonstrate an understanding of UML diagrams and their role in software design and system analysis.
