【摘要】 近年来,为解决软件危机,面向对象的构件化技术蓬勃发展。基于构件的软件体系结构是软件系统的组织结构,包括构件间的联系、约束,指导它们设计和演化的原理和准则。目前,已有一些公用的体系结构问世,如数据抽象和面向对象组织(data abstraction and OO organization)、层次式系统(layered system)等。而面向特定领域的基于构件的应用软件系统的体系结构的研究,则是一个较新的研究领域。本文设计并实现了一个基于构件的应用系统-----电信本地化电子商务应用。同时讨论了几种主要技术,包括构件的事务管理、构件的安全管理和构件自身的管理等。技术上,本系统采用了基于COM/DCOM的三层开发模型,融合了构件技术、C/S技术、数据库技术和Internet/Intranet技术,为面向特定领域的基于构件的应用软件系统提出了一个较完整的解决方案;功能上,在完善的数据处理功能的基础上,实现了Internet的信息浏览功能。整个系统的设计方案既保证了系统的实用性,又保证了技术上的领先性。该系统功能较完善,易于配置,容易维护,可扩展性强,具有良好的可集成性。目前运行结果良好。更多还原

【Abstract】 In recent years, in order to resolve “software crisis”, object-oriented component software technology is developing rapidly.The architecture of component-based application system is the organizational architecture of application system. It contains relationships among components, restriction, principles and theory that design components. Now, there are several common system architecture such as data abstraction and OO organization, layered system. But the research of the architecture of component-based application system that faces special domain is a fire-new research direction.This paper designs and implements a component-based application system--- e-commercial application of telecom localized. The paper emphasizes several key technologies such as component-based transaction, component-based security and component management.During the course of system design and implementation, on the one hand, system is based on component-based three-tiered architectural model, it uses component technology, C/S technology, database technology and Internet/Intranet technology, on the other hand, in addition to consummate data processing function, it offers Web function. The Design scheme not only has practicality but also has technical leading.System is easy in configuration and maintenance, has good scalability and integration. The system runs well now.更多还原
