What does the term 'data lineage' refer to?

• A. The cost of data storage
• B. Pathway of data from origin to usage
• C. Techniques for data encryption
• D. Methods for data backup

Answer: (B)

Data lineage refers to the pathway that data takes from its origin to its final usage, effectively mapping the flow of data through various stages of processing and transformation. This concept is crucial for understanding how data is created, modified, and consumed within an organization. By being able to trace the lineage of data, organizations can establish accountability, ensure data quality, and improve regulatory compliance. Data lineage helps in identifying the source of data, the transformations it undergoes, and the different systems and processes it interacts with over time. In contrast, the other options focus on different aspects of data management. The cost of data storage pertains to the financial considerations of maintaining data and is not related to its flow or transformation. Techniques for data encryption are concerned with securing data during transmission or storage, addressing privacy and security rather than lineage. Methods for data backup involve creating copies of data to prevent loss, which is also distinct from the concept of data lineage. Thus, understanding data lineage is vital for comprehensive data governance and effective data management strategies.
