一个用户主导的情景数据集成应用构造环境

User-steered Application Building Environment for Situational Data Integration

随着网络的普及和深入应用,人们希望共享和集成丰富的网络信息资源,以满足其个性化需求。文中提出了一个用户主导的情景数据集成应用构造环境DSS,用以支持大量不具备专业编程知识的最终用户自行利用既有的网络信息资源即时构造应用。DSS支持当前常见的网络信息资源,实现了交互式的网页资源个性化服务封装,并将Spreadsheet和嵌套关系模型相结合,提供了可视化的嵌套电子表格操作和公式语言,以支持用户进行数据服务的组合。通过案例和相关工作的分析比较,表明了DSS上述功能的有效性。

As Internet is being widely and deeply used,Internet has become a vast repository of online information resources. It is essential herein to enable end-users to develop situational data integration applications by themselves, and thus to profit from the online information resources＇ potential value, The paper presented a user-steered situational data integration environment called data service space（DSS）, which supports the most current used network resources, implements the ability to personalized wrap HTML Web page interactively,combines spreadsheet programming style and nested relational model, provides a set of visualized nested table operators and formula language, offers required agility and expressive power to support situational data integration by non-professional users. Use case and related work analysis reveal the potentials of DSS in situational data integration.
