讨论了在网络数据库环境中动态显示分子结构式的问题。数据库中存储分子的结构信息,在检索时动态生成分子结构式图,图形格式为SVG。SVG是一种矢量图形格式,又是一种基于XML的置标语言。用SVG可以动态创建分子结构式图形,而且文件是文本文件,体积小,易于编辑和信息交换。文中给出了从数据库中提取数据,动态生成分子结构式图形的方法。
The problem of dynamically displaying molecular structure in a networked database environment is discussed. The database stores the structural information of the molecules and dynamically generates molecular structural diagrams at the time of retrieval. The graphical format is SVG. SVG is a vector graphics format, but also an XML-based markup language. SVG can dynamically create molecular structure graphics, and the file is a text file, small size, easy to edit and exchange of information. The paper presents a method of extracting data from the database and dynamically generating the molecular structure graph.
