DataMart is the subset of datawarehouse. you can also consider datamart holds the data of one subject area. For an example, you consider an organization that has HR, Finance, Communications and CorporateService divisions. For each division you can create a datamart. the historical data will be stored into datamarts first and then exported to datawarehouse finally.
