摘要
MVC(Model-View-Controller)软件设计模式是目前广泛流行的软件设计模式之一。它将数据表示、流程控制和数据处理进行分离。通过采用MVC模式,可以简化软件开发,提高软件的伸缩性、扩展性和可维护性,达到提高软件质量的目的。结合面向对象的MVC软件设计模式和资源卫星数据的特点,文章提出并阐述了一种基于MVC模式的资源卫星产品数据地面存储管理系统的设计方法。该设计方法已应用于资源卫星地面系统的工程建设中。目前该业务系统运行稳定,证明了基于MVC模式的资源卫星数据地面存储管理系统设计合理、可行。
MVC（Model-View-Controller） design pattern was demonstrated to be one of the valid software development pattern which separates data display and flow control from data processing process. By using MVC design pattern, the process of software development can be simplified, and the flexibility, expansibility and maintainability of the software can be improved. And finally, high quality of the software can be obtained. Combining the object-oriented MVC pattern with the characteristic of Earth Resources Satellite data, this paper puts forward and expounds a method of designing ground data storage management system for Earth Resources Satellite based on MVC pattern. This method has been applied in the engineering construction of ground system of Earth Resources Satellite. Up to now, the ground processing system works well, which shows that the design method for ground data storage management system based on the MVC pattern is reasonable and feasible.
