Data Entity asset type

Data Entity assets are in the logical data layer and correspond to Data Domain assets in the conceptual data layer. You can think of Data Entity assets as system-specific implementations of Data Domain assets.

Example 

In the conceptual layer, multiple domains use the data concept Address, such as Employee, Event, and Customer.
In the logical layer, this is represented by the data attribute Address, which is used in several data entities, such as Customer Address, Event Address and Employee Address.
