Research And Design Of Graph Configuration System Based On UI Service Composition Method

Graph configuration system is to accomplish users’needs through a similar way as building blocks. However from the aspect of technical field, traditional graph configuration systems have to restart to draw a chart rather than reusing the existing chart resources. This means that traditional graph configuration system is low-reused. On the other hand, traditional graph configuration system is oriented to some special field such as coal mine, so the control logic is embedded in the system code. If a special field graph configuration system is used in other field such as electric power, its control logic is not suitable.In this paper, the graph configuration system based on UI service composition method proposes a method using SCA technology to separate user interface and control logic. It uses SCA to encapsulate control logics as services bound to user interfaces. When control logics are separated from user interface, users can add or update control logics flexibly by modifying its configuration. When user inter faces are separated from control logics, they can be reused by modeling at different layers. In this paper, the graph configuration system based on UI service composition method defines three models including:domain model, task model and show model.The graph configuration system based on UI service composition method mainly resolves the limit brought by the couple of user interface and control logic. By reusing UI services, it not only can cut down the cost, but also can let users to join the business process.First, this paper introduces the demands of this system, and then introduces its architecture. At a later time, some typical examples are given. The conclusion and the next work are given at last.
