Description: Data extraction is the act or process of retrieving data out of data sources for further data processing or data storage . The import into the intermediate extracting system is thus usually followed by data transformation and possibly the addition of metadata prior to export to another stage in the data workflow.Usually, the term data extraction is applied when data is first imported into a computer from primary sources, like measuring or recording devices. Today's electronic devices will usually present an electrical connector through which 'raw data' can be streamed into a personal computer.
