Software Component Technology

The data gives the key to make the decisions and the complexity of the information from the leads to the bad decisions. There it needed a method for improvement as a result of the amount of this data. This chapter discusses the developing of information systems, by their data, information, and the knowledge resulted by proposing a component identification approach and the management component for data management. The advantage of using component is to manage the information system by dividing it to several parts with less complexity.

The Performance Quantitative Model Based on the Specification and Relation of the Component

The trustworthiness of software is crucial to some safety critical areas. Performance is an important attribute of software trustworthiness. Software component technology is the mainstream technology of software development. How to achieve the performance of component systems efficiently and accurately is a challenging issue for component-based software development. In this paper, the performance quantification method of the component is proposed. First, performance specification is formally defined. Second, a refinement relation is introduced and the performance quantification method of the component system is presented. Finally, a case study is given to illustrate the effectiveness of the method.

Sharing Technology of the Tracking Telemetry and Command Software

The software sharing is the development trend of tracking telemetry and command software. How to develop quickly the tracking and controlling tasks software to adapt to the current experimental situation, and to ensure software quality, is a challenging subject placed in the face of software personnel. Using software middleware and software component technology, we can solve the problems of Tracking and Controlling Network acrossing operating system, Tracking and Controlling Software acrossing program languages, software reuse and other issues.

The Design of Online Examination System Based on UML & Component

This paper first discusses the related concepts of software component technology based on software component technology and software development method, and then based on the UML technology component extraction method and component extraction strategy, the system, the component extraction, the establishment of system function of each part and component model, software component technology is introduced into the online test system development, so as to improve the application software system development speed and efficiency and maintainability, reconfigurability and scalability.
