Designing ETL processes to integrate multi-field digital information resources

This paper introduces the traditional method and related technologies of digital in-formation resources integration in multi-field, and big data processing. It analyzes the integration process of digital information resources in multi-field which big data is applied. This paper discusses the main problems need to be solve in integration process of digital information resources in which big data is applied, such as the processing of heterogeneous data. ETL method is used to extract, trans-form, and load heterogeneous data, this paper also probes into the application of big data in the field of customer service in digital information resources.
