Research And Application Of User Interface Based On Component

User interface acts as the media by which software system communicates with users, and people pay more attention to it. The reiteration of the development of the interface handicaps the design and the development, so does the random of the design of it. It is possible to exploit the user interface with speed because of the rapid progress and wide adoption of the computer technologies; in particular, object-oriented technologies and component technologies become the power tools of the design of the user interface gradually. The system analysis and the component design of the user interface which emerge as the times require must change the design and the development of the user interface from theories to practices.The thesis looks on the design of the user interface of MIS in LongKou harbor bureau as the experimental object, then exerts the analysis and design of the user interface into the analysis and development of the information system and exerts the component technologies into the development of the user interface.Firstly, the thesis discusses how to divide the subsystem of MIS according to the data model in the analysis, secondly, designs the corresponding interface model according to the relation of entities in the data model and bring forward the viewpoint that the design doesn't center on the function but centers on users. It investigates the object modelization analysis methods and process in the analysis of the business model and brings forward the process and methods of the interface, that is to say, the views designs the interface abstractly, then designs it rudely and designs it roundly at last. The introduction the component into the development of the interface advances the efficient development of the interface and the maintenance of codes.The practice of the interface in LongKou harbor bureau avoids the random and advances the efficiency so that the praise comes in a continuous stream.
