Visualization And Editing Method Of XML-Based Instance Tree Of Management Information

Since the advent of XML Technology,it has developed very rapidly and has broad prospects.However,the documents described in XML are generally complex and difficult to quickly identify the information they express.Graphical expression can be used to represent XML schema information,and it is easy to understand,so there is a lot of research on XML schema to UML class diagram conversion.However,in many fields,it is necessary to convert objects described in XML into UML diagrams.For example,in the interface of network management,there is a complex relationship between managed objects.If a user views an XML document,it is hard to quickly figure out how many objects in the document and what kind of the relationship between the objects.At the same time,in the interface object testing and simulation process,if we can achieve the visualization of the interface object,it will bring great convenience.However,there is a lack of research and mainstream products in this area.In this paper,in view of the upsurge of data visualization and the status of the visualization of instance data and combined with the network management tester upgrade needs and instance data visualization needs.This paper presents an XML-based instance tree visualization method,and establishes the theoretical framework of instance data visualization method.This mainly includes the definition of XML data format,data model analysis,the instance tree construction,the instance tree presentation,the instance tree editing and the instance tree persistence,etc.In the XML instance data format definition,this paper gives an XML description of the class model and the class relational model.According to the defined data model,this paper gives a general flow of model parsing and the key steps and techniques involved.After the model is parsed,according to the parsed data storage form put forward my own construction method,used to construct the instance tree memory shape consistent with the data model and described in detail the method of construction.After building the instance tree,it needs to be rendered,for instance tree representation,this paper points out the key technologies involved in the process of tree representation.After the instance tree is rendered,the instance tree can be edited,for the model tree and presentation layer information synchronization issues involved in the editing process of the instance tree,this paper draws on the idea of two-way binding,gives a method of guaranteeing information synchronization.At the same time in order to ensure the recycling of model data,this paper gives a way to persist the drawn instance tree into model data,thus making the instance tree visualization method form a closed loop.Finally,using Web technology to build an instance tree visualization platform,to verify the instance tree visualization theory architecture and process system.Through the simulation data test,it is concluded that the instance tree visualization platform can effectively visualize the instance data and the instance tree visualization method proposed in this paper is feasible.
