摘要
为了提高各种数据资源的利用率,使用户能够以透明的方式访问分布的、异构的和动态的数据资源,按照最终用户的业务需求,对数据进行合并、分组、筛选和变换等操作,给出了一种脚本语言表示数据资源汇聚过程的可视化建模的方法。通过分析汇聚流程文件的表达能力,引入了分类模式映射检验汇聚过程的表达能力,给出了汇聚过程。
Resource Aggregation technology has become an important issue in order to enhance the utilization rate of data and enable users access distributed heterogonous and dynamic data resource in a transparent way, and can be driven by the end user to merge ,group, filter, transform these data and do other operations according to business needs.This paper illustrates this integration process by a scripting language according to the situations emerged during these processes.Meanwhile, with the purpose of discussing the expressing power it introduces scheme mapping and then sorts them to classify which schemes can be expressed correctly and which are not.Also, it works as the basis to syntax checking.
