基于W eb的大型数据预览系统的设计与改进

摘要

由于传统的大型数据预览系统无法有效掌控复杂多变的大型数据，数据预览效果差。因此，提出基于Web的大型数据预览系统，该系统由大型数据预览模块、大型数据监管模块、统计报表模块和计算机组成。大型数据预览模块由浏览器、服务器和大型数据库组成，用户选择所需查询数据的标题后，浏览器会将该标题的指令传输给服务器，服务器根据指令进行大型数据的压缩处理，并反馈到浏览器中进行显示。大型数据监管模块可将大型数据预览模块中抽象的大型数据变换为直观图像进行调整，调整后的图像会被转换成大型数据格式并传输给统计报表模块，统计报表模块将整个系统的大型数据汇总成各类报表并显示在计算机上。系统的软件设计部分给出了大型数据节点分布的调节算法和流程，以保证Web大型数据预览系统的正常运行。实验结果表明所设计的系统具有较高的稳定性和准确性。%Because the traditional large data preview system cannot effectively control complicated large data,and its data preview effect is poor,a large data preview system based on Web is put forward. The system consists of large data preview mod⁃ule,large data monitoring module,statistics report module and computer. The large data preview module is composed of brows⁃er,server and large database. While a user selects the title of query data required,the browser will transmit a query command of the title to the server,the server compresses the large data according to the instruction,and then feedback to the browser for display. The large data monitoring module converts the abstract large data in large data preview module into visual image for ad⁃justment. The adjusted image is converted into large data format and transmitted into statistics report module. The statistics re⁃port module makes the large data summarization of the whole system into all kinds of report forms and displays them on the com⁃puter. As for the system software design,the distribution adjustment algorithm and process of the large data nodes are given to ensure the normal operation of large data preview system based on Web. The experimental result shows that the system has high stability and accuracy.
