Information System Developing Method Based On Component Technology

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.
