An approach to improve the quality of object-oriented models from novice modelers through project practice

Frontiers of Computer Science 2017年第3期11卷 485-498页

作者： Zhiyi MA Software Institute School of Electronics Engineering and Computer Science Peking University Beijing 100871 China Key laboratory of High Confidence Software Technologies (Peking University) Ministry of Education Beijing 100871 China

The defects in object-oriented models will result in poor quality of applications based on the models, and thus it is necessary to know which defects often occur in practice, to what extent they occur, why they occur, and how they can be prevented. To gain deeper insights into these problems, this paper discusses how to improve the quality of object- oriented models from novice modelers through project prac- tice. This paper summarizes a set of typical quality defect types from a large number of the defects, and confirms them through our project practice. Moreover, the paper analyzes the improvement of the quality of object-oriented models by quantifying the level of occurrence for the defect types in dif- ferent phases of the project practice, and presents preventive measures by analyzing the causes for the defects to occur in object-oriented models in the aspects of syntax, semantics, and pragmatics.
