摘要
讨论了在Web数据库环境中处理分子结构式的问题。分子结构式可存储为静态图片格式或动态结构式格式。静态图片格式具有平台无关性 ,动态结构式格式则具有可编辑性及动态显示的优势。在关系数据库中 ,既可将分子式文件名或所在路径作为数据项 ,也可直接将分子式文件本身作为数据项。文中给出将分子式文件存入数据库的程序流程的示例。使用插件 (Plug in)或ActiveX控件 ,可在Web浏览器中直接显示动态的分子结构式。文中分析了二者各自的优势 ,并结合ASP和Chime插件技术 ,给出了在数据库中检索分子结构式的具体实现方法。
The processing of molecular structures in a Web based database is discussed in this paper. A chemical structure can be saved in either a static image format or an “active” format. The static image format is platform independent, while the “active” format shows advantages in edition and display of a molecular structure. For a chemical structure, the storage term in a relational database can be either the filename of the molecular structure file or the whole file as an object. The program of molecular structure storage in databases is presented with example in this paper. The molecular structure in “active” format can be displayed in Web browsers by using plug ins or ActiveX controls. Based on ASP and Chime plug in techniques, examples on the molecular structure retrieval and display from the Web based database are demonstrated.
