Component Technique,Component Object Model,and Information System Development Method
信息系统开发方法的选择对信息系统建设的成败至关重要。应用传统的信息系统开发方法进行信息系统的开发建设，软件的可重用性很低，系统的开发效率也很低，信息系统的可升级性和扩展性差。这就使得传统的信息系统开发方法很难适应信息系统不断发展的要求。针对传统的信息系统开发方法存在的不足，我们将组件技术引入信息系统建设中。组件技术是面向对象技术的最新发展，它具有开放性、灵活性、可管理性、安全性和透明性等特点。将组件技术应用于信息系统的建设中，可以提高软件的重用性，从而提高系统的开发效率。 本文从信息系统的开发方法着手，对各种信息系统开发方法，总结传统的信息系统开发方法的不足，提出了基于组件的信息系统开发方法，介绍了组件技术的概况和几种常见的组件技术规范，并以Microsoft的组件对象模型为例，介绍了组件的实现。最后结合本人在科力恩中小学信息管理组态平台的组件开发和应用实践，介绍了基于组件的信息系统开发方法，最后对组件技术在信息系统中的应用和发展进行了展望。
Making a choice on the developing methods of the information system plays a vital role in the construction of information system. By using the traditional methods of information system,the reusability of software and the development efficiency of the system are low;besides,the possibility of upgrading and extending of the information system is little. So it is hard for traditional developing methods to satisfy the demands of the continuous development of the information system. In order to make up for the defects and drawbacks of the traditional methods,component technique is adopted and employed in the construction of information system. Component technique is the latest development of the object-oriented technique,bearing such qualities of being open,flexible,manageable,safe and transparent,etc. With this new technique applied to the construction of information system,the reusability of the software and the development efficiency of the system can be raised.Beginning with he introduction of the development methods of information system,this thesis explains and illustrates a variety of development methods,summarizes the shortcomings of the traditional ones,offers and raises the development method based on component technique,iterates the general status and the realization of component with Component Object Model of Microsoft. And finally,the information system development methods are expounded on the base of my own practice of the development and application of component in the Dalian Clean Automation Co. Ltd,and the prospect of the utilization of component technique in the information system is foreseen.
