Integrating data means combining disparate datasets to form a single, coherent whole. The steps involved in this process are discovering and gaining access to the various data sources, mapping the data to a common format, and settling any differences or discrepancies between the various data sets. If you have data stored in different places, you can only get a full picture by integrating it. Integrating data when other sources use different data formats, structures, and semantics can be challenging.
