构件层级开发模型的研究与应用

摘要

设计了构件层级开发模型，重点研究了模型中界面表现层、业务逻辑层和数据通道层，并结合构件层级开发模型给出了全景监测构件实例。构件层级开发模型采用层次化开发方法，明确了各层功能边界和实现方法，解决了构件内部组织和结构问题，确保清晰的功能职责划分，分离构件开发的关注点，提高了构件的可复用性以及软件的开发效率。%The component hierarchical development model is designed. The UI layer, business logic layer and data access layer in the model are studied, and the example of panoramic monitoring component is developed by combining with component hierarchical development model. The component hierarchical development model adopts layer development method, in order to explicit the functional boundary and implementation method of each layer, solve the organizational and structural problems within the component, guarantee the clear functional division of responsibilities, separate the component development concerns, and enhance the reusability of component and the development efficiency of software.
