An Online Examination System Based on UML Modeling and MVC Design Pattern

In this paper, the design and implementation of an online examination system for medical students are introduced. The system aims to improve teaching quality, motivate students´ self-learning and refresh basic and clinical knowledge for medical students and young doctors. In the design of this system, we applied Unified Modeling Language (UML) modeling, such as use case diagrams, sequence diagrams, activity diagrams, etc. The functional requirements are traced from use case models to component model via analysis and design models, thus the components derived using this approach form the components of Model-View-Controller (MVC) architecture. It´s proven very helpful to smooth the communication between medical teachers and software developers, increase code reuse and speed up the development.
