The various features of an EDW are:
- An EDW may or may not interact with Data Mart. The most important aspect of any Data Warehouse is the consistency of information.
- An EDW may have same level of granularity as a Data Mart. This means that the data from the Data Mart will be dumped into an EDW.
- An EDW may have more detailed level of data than a Data Mart. This means that the data requirement is at a more granular level that may not be catered by the Data Mart.
