"A comprehensive data migration system performs a variety of functions. Initially, it will create subsystems that allow for the management of the system itself. It will then seek out external sources of data and began to import information into the data warehouse. During the import, the data is verified and scrubbed to make sure it is the appropriate information and that there are or no threats embedded within the data. The system then formats the data so that it can be used in a variety of different ways, including application development, data mining, and extraction for decision-making processes."
