What does the term 'data lineage' refer to in data integration?

The term 'data lineage' refers to the history of data transformation and movement. It provides a comprehensive overview of how data flows through various processes within a data integration environment. This includes understanding the origin of the data, the transformations it undergoes, and the final destination it reaches in the data pipeline.

Data lineage is critical for organizations as it helps in tracking the data from its source to its final form, which is crucial for data quality, compliance, and governance. By mapping out this journey, organizations can identify any issues in the data processing steps, ensure regulatory compliance, and improve data management strategies. Additionally, it aids data analysts and engineers in making informed decisions about data usage and integrity.

The other options focus on different aspects of data without capturing the essence of data lineage. The format of the data, storage location, and size of data sets are all important characteristics, but they do not encompass the historical and transformational context that defines data lineage.
