Data Ownership

The principle that defines which business or technical role is responsible for the quality, definition, and use of specific data domains.

Data ownership is one of the most critical clarifications in enterprise data management. If a data field is wrong, incomplete, or inconsistent and it is unclear who is responsible for correcting it, governance may fail in practice. A data owner is not merely the technical system owner; often it also includes the stakeholder who understands the business meaning and usage context of the data. Without clear ownership, data quality cannot be improved in a lasting way. When responsibility is diffuse, quality becomes diffuse as well.
