A data custodian position is responsible for monitoring the archival, transfer, and transmission of information within an organisation to ensure compliance with all policies and procedures. Data custodians are responsible for maintaining databases and their contents.

Database administrators are another name for a data custodian. Data stewardship is an important role in information management and governance. To protect sensitive information, it is crucial that only authorised parties have access to it.

Although the two terms are commonly used interchangeably, the work of data stewards is distinct. Knowledgeable individuals, known as “data stewards,” are in charge of vetting information sources for reliability and establishing guidelines for how they should be used. However, data custodians are responsible for ensuring that the security rules and standards outlined by data stewards are met.

As data’s value has increased over the years, so has the need for careful administration. Data governance cannot be efficient or successful without clearly defining who does what. This will not only improve efficiency but will also encourage responsibility. One of the persons in charge of data governance is called a “data custodian.”
