The role of the Data Steward is therefore to implement effective day-to-day control of data mapping and data management.

This Data Steward will be in charge of collecting the data while ensuring its security. For example, he can draw up specific rules of relevance, enabling the quality of the collected data to be measured accurately.

Why are Data Stewards important?

While a Data Owner is going to be involved in the acquisition and appropriation of a set of data, he or she is not going to be involved in the preservation of the data and its recording. The Data Steward will have global visibility on a data acquisition and mapping project, while being involved in the various means put in place to achieve the defined objectives.

The Data Steward is the keystone of any good Data Governance project that wants to have the right combination of processes, technologies and business teams to be effective.
