define data governance
âData Governance is a system of decision rights and accountabilities for information-related processes, executed according to agreed-upon models which describe who can take what actions with what information, and when, under what circumstances, using what methods.â. When you refer to governance, be careful! Depending on the context, âData Governanceâ could refer to: 1  organizational bodies. 2  rules (policies, standards, guidelines, business rules). 3  decision rights (how we âdecide how to decideâ).
