摘要： 针对远程教育收费管理困难和学分制学费计算复杂化的问题，从特定收费业务需求出发，构建了一种基于多层体系结构的智能性远程收费系统，阐述了该结构各层的功能及MVC模式的应用。描述了该结构中的业务服务层的功能模块结构，学分费的智能性计算方法及公共服务层的基于原语的接口定义。该系统架构已在实际系统中应用，具有松耦合、可重用、易扩展、易集成的特点。

Abstract: Focusing on the difficulty of fee management and credit fee calculation in E-Learning, this paper analyzes the specific fee service, and presents a design for intelligent E-Learning charging system based on multi-layer architecture. It expounds the functions of each layer of the system and MVC model application. It describes the function module architecture in application service layer, and the intelligent arithmetic of credit fee calculation, and the common service interface design. The architecture has loose coupling, reusability, scalability and integrality, which has been approved in real system.

Key words: intelligent charging system, multi-layer architecture, application service layer, common service layer, model view controller(MVC)
