A Common Data Format is a data model that brings together disparate datasets into one consistent organization. It is a data model that represents the way a data consumer would like to organize its data. Typically, a data consumer receives data from multiple data producers. Each data producer may have its own data model and data semantics. When on-boarding such hybrid datasets, a data consumer would need to transform the ingested datasets into a consistent model so that aggregation or comparison operations can easily take place. A Data Mapping process transforms source data into a Common Data Format.
