Data governance is the process of ensuring high quality, high availability, usability, integrity, and security of the data that's used across the organization. Data governance helps the organization to efficiently manage the data it has and get more value from that data, along with making the important value of that data visible to users.
Data governance enables and encourages good behavior about data and also limits any behavior that create risks. This objective is similar, irrespective of whether we are in a big data environment or a traditional data management environment. It helps the organization identify who is responsible for the data, collaborate to set policies and decisions, analyse how the data is used and what it is for, understand how and where metrics and information are derived, and determines the impact of any change in data on the business.
