The Visualization Research Of Data Register Center In DOA

In today's digital economy era, people need to analyze a lot of data to extra ct information, support decisions, and gain value. The value of the data is often implicit, and we need to sum up and extracted from those data.Then the reflector of data's value must in the need of visualization technology. Benefit from the promotion and search of cloud computing technology and big data in recent years. the proposing of "DOA(Data Oriented Architecture) guides the new development direction of the software architecture. It describes a data-oriented security system method and system.The central of DOA is "data-oriented and data-centric". It emphasize the data first. Together with increasingly open environment and rapid expanding of data in the era of big data, the hidden value of data attracts experts and scholars in various fields to analyse and mine. The core component of DOA is DRC(Data Register Center). it is the basic module of data management and data service provision. The data in DRC are diversed in sources and different in structure, and are dynamic changing. Together with a variety of massive data register information are stored in the DRC, So DRC is a large distributed database cluster application. As a logical resource pools,DRC contains all the data.DRC's visualization can help the user to hold holistically and analyze intuitively of data. DRC's visualization is good for data statistics, query and management and can realize DRC's function conveniently and efficiently.At the same time, it can improve the DOA's system and function, which is the focus and significance of this paper.This article is on the basis of DOA theoretical and DRC registration mechanism, and discusses unified identification,data attribute information of DRC. Meanwhile, this article does preliminary research on DRC'S visualization and designs a data registration scheme. Finally it has realized the diversified visualization of DRC's data resources.The main research contents of this paper are as follows:1) A theoretical study of the DOA structure and DRC registration mechanism.Through the statement of DOA's theoretical basis, the bigdatal's difficulty to dig and analyzing, to export DRC mechanism which registers and defines uniformly of data.Then this paper discusses the function of DRC,the deployment of DRC,the data classification standards of DRC.2) Studying the key techniques and methods of visualization, and analyzing the key problems of DRC's visualizationBased on the key technology of visualization,the paper compares and analyzes different types of visualization methods and tools. Then the paper focuses on t he research of the key problems of DRC's visualization.Those content provides idea on realizing DRC's visualization3) Designing DRC's visualization programme to complete the visualization presentation.To analyze the visual requirements?process description and function of DRC. Then designing reasonablyDRC's visualization scheme.That includes framework designing and implementation model.Finally, completing initially DRC's visualization and fundamental interaction.4) Testing the visual function of DRC in the specific application of DOAAdding DRC visualization module in the DOA management platform to test results of DRC's visual function.The innovations and achievements of this paper are as follows:1) Based on the DOA architecture, researching the registration standards and programme of DRC.Based on the DOA which is with "data" as the starting point. This paper clearly states the DRC's basic functions on data management and data service providing.And according to the different data classification,this paper discusses detailedly about data registration standards and content Then,the paper proposes basic criteria of DRC's data registration.2)To realize the basic visualization of DRC.From the point of data,this paper puts forward visualization scheme and design model of DRC. Supported by key technology,the paper realizes visualization function about DRC and provides users with data query and statistics.Finally, achieving the purpose of effectively presenting DRC's visualization.Then,the paper tests DRC's visualization function in specific DOA planform and reveal diversified of DRC's data.
