# Reference Data Management

The "Reference Data Management" tab tracks changes to reference data units and their attributes within OvalEdge. This includes actions performed by:

* **Reference Data Admin (RD Admin):** Creates or deletes reference data units.
* **Steward of a Specific RD Unit:** Updates the unit's attributes.

The audit log captures the following details:

* **Reference Data Unit:** Name of the unit affected
* **Connector:** Connector associated with the reference data
* **Object Type:** Type of object linked to the unit (e.g., Table Column)
* **Attribute Name:** Name of the specific attribute (e.g., table column name)
* **Action:** ‘Add’, ‘Update’, or ‘Delete’ (for Stewards, ‘Updated’ refers to attribute changes)
* **Changes:**
  * From: Previous value of the attribute or unit
  * To: New value of the attribute or unit
* **Updated By:** The user who made the change
* **Updated On:** Timestamp of the action

**Sorting and Filtering:** Audit details can be sorted/filtered by RD Unit, Connector, Action, and Updated On.
