| 摘 要： | 文章提供一种基于语义的可定制数据切分和动态加载方法,它能够对源数据库建立基于语义的元数据描述,根据不同用户的数据需求,依据数据的语义相关性,转化并归纳为通用的策略模版,基于策略进行数据的切割和数据的级联抽取。之后,采用容错式动态加载方法。这在一定程度上实现了异构数据库之间的批量数据迁移。

| Abstract: | The paper presentes a method of semantic-based ＆ customizable data extraction and dynamic data loading. It provides the de- scription of semantic-based metadata on source database and generates the general tactic mode according as data requirement for different user and semantic-related data. Based on strategy the corresponding data extraction approach was proposed and implemented. In the end, the meth- ods of fault-tolerant and dynamic data loading are adopt to realize bulk data migration among different structure database on a certain extent. |
