Governance (data management) is the formal system of organizational structures, policies, procedures, standards, and controls implemented to manage data as a critical enterprise asset across its entire lifecycle. It defines roles, responsibilities, and processes to ensure data quality, integrity, security (linking directly to database security), usability, and compliance with internal requirements and external regulations (potentially drawing upon principles relevant to international constitutional law and international finance). Integral to effective knowledge management and responsible sourcing management, this concept is crucial for enabling reliable decision-making, managing operational and compliance risks, and supporting data-intensive applications such as those required for sustainable cities. Its primary significance lies in establishing trust in data and optimizing its value for strategic objectives.
