【摘要】 针对企业异构信息系统中的海量数据,本文根据集装箱运输信息系统的实际状况设计了一个层次化的ETL方案,实现了ETL异步运行方式。给企业不同数据源数据的抽取定义了程序化的接口,便于对接口的二次开发,增强了系统的可控性和统一性,提高了ETL系统的运行效率。更多还原

【Abstract】 In view of magnanimous data of the isomerism information system of enterprises,according to the actual condition of the information of the container transport,a hierarchical ETL plan has been designed in this article,the asynchronous way of ETL has been realized.The programmed connection for the enterprise has been defined for extraction of the different data,controllability and the unity of the system has been strengthened, operating efficiency of the ETL system has been enhanced.更多还原
