What role in a data governance is typically responsible for day-to-day oversight of data use?

Data processors are entities that process data on behalf of a data controller, focusing on technical processing rather than policy oversight or day-to-day governance.

Data custodians are primarily responsible for the technical environment, infrastructure, and security of the data storage systems, rather than the day-to-day use and quality of the data itself.

Data owners hold ultimate accountability for the data within their domain, defining policies and ensuring its value, but they typically delegate day-to-day operational oversight to data stewards.

Data stewards are crucial for data governance as they focus on the operational aspects of data, including ensuring data quality, managing metadata, and implementing data policies on a daily basis within specific data domains.
