基于语义的数据库信息发布模型

Universe-based database information publish model

随着因特网技术的发展 ,Web上数据库信息发布的需求迅速增加。传统开发模式中开发人员工作量大 ,软件不能复用。提出了基于语义的数据库信息发布模型 ,将语义描述者通过语义描述平台提供的数据集语义、数据操纵语义和发布样式语义分别存储在数据字典层、数据操纵层和发布样式层 ,再通过语义解析器解释生成发布页面。该模型实现了数据库信息发布的灵活定制和软件复用 。

The development of Internet demands more and more database information publish. The traditional developing method makes developers do heavy programming and provides no reusability. A universe based database information publish model was proposed in this paper. The data set, data manipulation and publish style universe which were provided by universe constructor using universe describe platform are stored respectively in the data dictionary layer. data manipulation layer and publish style layer. The universe parsing implement parsed the universe and construct a publish web page. This model customizes database information publish conveniently, makes the software reuse and relieves the developers of repeatedly similarly heavy programming.
