Data Lineage: Unveiling the Hidden Pathways of Data Flow

In the ever-evolving landscape of data management, one concept takes centre stage when it comes to ensuring accuracy, transparency, and reliability in data processes – and that’s Data Lineage!

Whether you’re a seasoned data professional or just starting out in the world of data management, understanding data lineage is crucial for maintaining data integrity and making informed decisions.  In this article, we’ll explore it’s essence, types, as well as how it differs from data mapping.

Data Lineage

What is Data Lineage?

Data lineage is a visual representation or documentation of the complete journey that data takes, as it moves through an organisations systems and processes.  It includes information about data sources, transformations, and destinations. 

It will help you answer questions such as:

  • Where does data come from?
  • How is it transformed?
  • Where does it go?
  • Who is responsible for it?

Data lineage tools such as DataGalaxy, provide a clear end-to-end view of data, revealing the relationships and dependencies that exist within a data environment.

An Example of Data Lineage:

Imagine a retail company with both physical stores and an on-line platform, that collects data from different sources including, in-store purchases, on-line orders, and customer reviews. 

Data lineage can provide a clear visualisation of how this data is gathered, integrated, and transformed.  For instance, a customer’s purchase data might flow from point-of-sale systems in physical stores to a centralised database in headquarters.  From there, it’s linked with the online platform’s data, showing a comprehensive view of the customer’s behaviour.

If the retail company wants to analyse which products are popular among online shoppers, data lineage helps trace how the relevant data points were aggregated and transformed to provide valuable insights.

Types of Data Lineage:

There are two different types – business lineage and technical lineage

Business lineage caters to business analysts by offering a high-level view of data sources, ensuring reliability without delving into every data entry. 

On the other hand, detailed technical lineage serves IT and data architects by providing insights into transformations performed, table lineage, column lineage, and query-level lineage within data pipelines.

By combining both business and technical lineage, organisations can attain a comprehensive understanding of their data.  With this, your data users are empowered across all departments and roles to make precise business decisions.

Distinguishing Data Mapping from Data Lineage

At this point, we think it’s important to note what is the difference between data mapping and data lineage?

While both are related concepts, they serve different purposes.

Data mapping focuses on the connections between different data sources and destinations. It’s like creating a network map that shows how data entities relate to one another.

Data mapping is critical for designing efficient data integration processes, ensuring that data is correctly transformed and loaded from source to destination.

Data Mapping

Data lineage, however, goes beyond the connections and delves into the actual journey of the data itself. Answering questions like:

  • “How did this data get here?”
  • “What transformations were applied?”

Essentially, it provides a timeline and view of how data is transformed over time as highlighted in the image.
