What is Data Lineage?
Data lineage is a process of getting an idea about where the data is coming from, analyzing it, and consuming it. It reveals where the data has come from and how it has evolved through its lifecycle. It traces where the data was generated and the steps in between it went through. A clear flowchart for each step helps the user understand the entire process of the data lifecycle, which can enhance the quality of the data and risk-free data management.
The main objective of it is to track the data from where it has been generated and the path it follows throughout its lifecycle. Some significant data-driven companies like Netflix, Google, Coca-cola, Microsoft, and Uber use data lineage for many purposes.
- Data lineage enables companies to track and solve problems in the path of the data lifecycle.
- It provides a thorough understanding of the solutions to errors in the way of the data lifecycle with lower risk and easy solution methods.
- It allows companies to combine and preprocess the data from the source to the data mapping framework.
- Data lineage helps companies to perform system migration confidently with lower risk.

Data Lineage vs Other Data Governance Practices
Data lineage is a critical component of data governance and is closely related to other data governance practices, such as data cataloging and metadata management. However, data cataloging is the process of creating a centralized inventory of all the data assets in an organization. At the same time, metadata management involves creating and managing metadata associated with these assets.
Data lineage helps establish the relationships between data elements, sources, and flows and provides a clear understanding of how data moves throughout an organization. It complements data cataloging and metadata management by providing a deeper insight into data’s origin, quality, and usage.
While data cataloging and metadata management provide a high-level view of an organization’s data assets, data lineage provides a granular understanding of how data is processed, transformed, and used. Data lineage helps to identify potential data quality issues, track changes to data over time, and ensure compliance with regulatory requirements.
