Abstract
In order to realize ETL processing of unstructured data, the current situation and demands of data integration are analyzed. The popular CWM model and its application in ETL are described. The different features between structured dato and unstructured data are analized to get the property of unstructured data. This work provides a foundation for meta-data of unstructured data, and meets the demands of unstructured data ETL and data integration.关键词
