Object-oriented analysis methods were introduced and a set of models were built based on the unified modeling language (UML), such as the function of the system, object structure, behavior and activities, as well as implementation of the system. After appropriate conversation, and with QM tool, the code could be automatically generated directly from UML model based on quantum platform. Compared to the usual development method, there were obvious advantages of the proposed method in development, maintenance and code reuse, etc.
