摘要
结合数据抽取处理的多源性、数据预处理功能的集成、数据抽取处理描述信息的重用等特征 ,讨论数据抽取事务逻辑划分及组件包设计 .给出数据抽取包的定义、包的逻辑结构及可视化管理工具设计 .提出用元数据生成数据抽取包、用 DTS包作为数据抽取包的执行载体的方法 ,以提高数据传输性能和简化系统实现 .
Combining with such characteristics of data as multi source of their extraction and processing, integration of their pre processing function, and reusing extraction, processing and description of information, a discussion is made on the logical devision of data extract affairs and the design of component package. On this basis, the authors give the definition of data extract package, logical structure of package and the design of visualized management tool; and put forward the methods of use metadata to generate data extract package, and use DTS package as executive carrier of data extract package, by which the performance of data transmission can be improved and system implementation can be simplified.
