Research And Implementation Of Subject-Based Network Information System Development

With the development of the network, the Network Information System (NIS) becomes a hotspot in aspects of software development and its application. At first, this paper introduces the characteristics of NIS and developing methods that are belonged to NIS. The paper analyzes advantages and disadvantages of the traditional developing methods. Then absorbing the advantages and being based on our experience in the system analysis and development, a new developing method based on subject resource is presented.The main idea of this method is to analyze, design and implement the subject resource of NIS, so as to develop the NIS by means of integrating existed Web frame and the subject resource. When the requirement of application built on the ground of NIS is changing on the stage of development and maintenance, NIS has good stability, strong cohesion, reused, good maintainability and easy to realize. In this paper, the concepts which used in the developing method based on subject resource, are clearly defined. Except this, we also elaborate the principle of developing method and developing process, and use demonstration to prove the feasibility and validity of the method.In order to make convenient for using the developing method based on subject resource, the author designs and implements a set of case tools based on the subject resource method. Finally, the paper gives the main design thinking of the assistant development system.
