| With the increase of software development scale and complexity, as well as the boost to the need of software development speed and quantity, software crisis has been exposed increasing. It's emergency to increase the efficiency of software. To conquer software crisis, theory of software reuse is presented and has been under study. The software components is considered as the main measure to solve software crisis ,improve software productivity efficiency and software quality, and enhance the adaptability to outside noise.As the development of the world and our country becoming more and more strong, more and more people begin to learn Chinese. As the rapidly development of network technology and popularization of computer, more and more people begin to study on line. Online Chinese-Study System become urgently. There are some Chinese-Study Systems and they have met the needs of the learners to a great extent, but there are still some problems needs to solve.Based on the two factors above, This thesis do the deeply research on software component and software development technology based on components. This thesis is detail about the definition of component and includes definition, classify, describing method, realization and studies the fundamental idea and the lifecycle model of software development based on components. It develops the designing principle of components and components integration software system etc.Finally, in giving corresponding developing examples, the thesis discusses the application of software development technology based on components in Online Chinese-Study System. Putting it into to make good use of this technology in practice, and test that this technology has great advantage for software design rapidly. |
