Defining Data Lineage and its Key Concepts
Data lineage refers to the process of tracking and recording the origin, processing, and movement of data throughout the ETL pipeline. It involves capturing metadata about the data, such as its source, transformations, and loading processes. Data lineage is critical for ensuring data quality and integrity, as it provides a clear understanding of the data's provenance and processing history. Key concepts in data lineage include data provenance, data transformation, and data loading.
Data provenance refers to the origin and history of the data, including its source, creation, and modification. Data transformation refers to the processing and manipulation of the data, including aggregation, filtering, and sorting. Data loading refers to the process of loading the data into the target system, including data warehousing and data lakes. Understanding these key concepts is essential for designing and implementing a data lineage architecture that integrates with existing ETL pipelines.
