Design And Implementation Of Data Visualization System Based On Object Features

With the rapid development of the Internet in recent years,the scope of information technology in our country is expanding and deepening.Followed by a huge amount of information flow,and various industries,fields are experiencing the objective facts of the explosive growth of data.In these massive data,people often can not effectively show the law between the data and the internal relationship between the data.And how to simple and effective to understand and use these massive amounts of data for the related management department to provide accurate,objective decision-making basis,is a problem to be considered.The most important information interface of human being is visual perception,which gains 80% of information from the outside world.As the saying goes,"a picture is worth a thousand words",it illustrates the importance of graphics or image visualization.But in the traditional data visualization scheme,using the object to program developers and data analysts,and are not proficient in various industries or fields and demand,which makes the development process of the system and the subsequent maintenance is laborious.It is in this background,a visual application system based on object feature set was designed and developed.The primary works in this thesis are presented as follows:1.Establish the procedure of dealing with data features and charts,in which data is divided into seven kinds of basic characteristics,in which data is divided into seven kinds of basic characteristics,and the chart is divided into seven top level characteristics and multiple secondary display characteristics,but also the attributes of chart are also characterized.2.In view of the characteristic chart properties,this thesis divide the chart attributes into eight kinds of general features,and make the user realize the configuration of the relevant attributes and the customization of the chart attributes by the feature mapping method.3.In order to facilitate business users to quickly and easily achieve the visual effect,this thesis combines the visualization process with the data features and chart features.Reduce the inefficiency problem when there is a change in demand for program developers.4.This thesis,the designed system is applied to the field of scientific research management,and the online data,the offline data based on documents and the structured data based on relational database are visualized.This system is designed and implemented by the data characteristics and chart features common to guide the way that business users can clearly understand the basic state information,and combined with the visual analysis of various data related business knowledge flexibly and quickly,reduce the application of data analysis technology threshold significantly,enhance application efficiency.
