摘要
随着Internet技术的普及和发展,基于B／S结构的实时数据发布已成为信息系统中一项重要的功能。SVG作为基于 XML的网络矢量图像格式,具有其他图像格式所不可比拟的优势。根据SVG的技术特点,将SVG和实时数据库相结合,在实时信息系统中利用SVG技术发布实时数据是适用于B／S结构、具有应用前景的一种解决方案。该方案的关键技术是定时刷新基于XML的SVG文本文件。实践表明该方案具有良好的实际应用表现,能够有效地减轻网络传输的负担、缩短用户界面的响应时间。
With the popularization and development of Internet technology, the real time data publication based on B/S structure already becomes an important function in real time information system. As an XML - based network vector graphics format, SVG has many advantages over other graphics formats. According to the SVG＇s technical characteristics, this paper studies the integration of SVG and real time database, and presents a model of real time data publication. The model adapts to the B/S structure, and has good prospect. The key point is to refresh the svg＇s file at intervals. An instance illustrates that the approach has better practical performance, and effectively decreases the network overload and reduces the response time of user interface.
