An entity is a file or table stored in your repository and associated with a data source that you have identified.
Depending on the structure of the source data, an entity can be one of the following:
|
Entity Type |
Data Source |
|---|---|

Physical Table |
Data source is a relational database. |
|
Physical File |

|
IMS segment or IDMS record |

|
Schema structure without data |
Not dependent on a specific type of data source. |
The repository uniquely identifies each entity with a reference number, allowing for entities with duplicate names to exist.
