A Longitudinal and Comparative Study of Complexity Metrics for UML Class Diagrams through Internet Banking

With the development of electronic-commerce (EC), more and more banks, such as Bank of China, launch Internet banking services in pursuit of broader application and advanced development of e-commerce and of a view to better fulfill the banking services required by corporations and individuals. To help software developers analyze reliability, maintainability and complexity of those systems modeled by UML, this paper analyzes and compares several typical complexity metrics for UML class diagrams from different types of relationships, metric values, and theoretical & empirical validations. Finally, the authors discuss their advantages and disadvantages as well as the existing problems and the prospects.
