It includes the establishment of policies and procedures for data management, defining data ownership and accountability, and ensuring compliance with regulations.
2. Master data management is the practice of identifying, defining, and managing the key data entities that are critical to an organization's operations. It involves creating and maintaining a centralized and authoritative source of data that is used across the organization.
3. Metadata management involves the management of information about data such as its definition, lineage, context,and usage. It helps to ensure that data is accurate, consistent, and accessible, and provides context and understanding for users.
4. Analytics refers to the use of statistical and computational techniques to analyse and interpret data, and derive insights that can inform decision-making.
5. Data privacy involves the protection of sensitive and personal data from unauthorized access, use, or disclosure. It includes implementing measures to ensure data is collected, stored, and processed in accordance with applicable privacy laws and regulations.
6. Data architecture refers to the design and organization of an organization's data assets, including its databases,data warehouses, and data lakes. It includes the selection of appropriate technologies to support data processes, the development of data models, and the establishment of data standards and policies.
7. Data integration involves the process of combining data from different sources into a single, unified view. It includes activities such as data transformation, data cleaning, and data consolidation.
8. Data quality refers to the accuracy,completeness, and consistency of data. It involves ensuring that data is fit for its intended purpose and free from errors or inconsistencies that could affect its usefulness.
