Thus it is inapplicable or unbelievable. To evaluate software maintainability objectively,the software configuration management( SCM) data are collected to establish a maintainability model. Based on the hidden Markov chain( HMC), a three-state maintainability estimation model is constructed. To validate the feasibility of the model,a real software example of software maintenance activity is given and the result from the example shows the effectiveness of the proposed method.展开更多
The main structure and key techniques of our Virtual Exhibition Software are summarized. It demonstrates the practice of Software Engineering during the development of our project and discusses the use of UML in it.
