What is data lineage

First, ask yourself what does lineage mean? 

To understand something’s lineage is to know where it came from and to know the path it took over its lifecycle to get here, including all the various encounters and events that transformed it along the way. And so it is with data lineage.

At its core, data lineage provides a clear and visual representation of data provenance, essential for any organization. It offers a continuously updated record, with which the user can then; 

  • Determine the data’s point of origin
  • Track the movement of data through an organization 
  • Observe it’s various transformations along the way
  • Keep a log where the data has been stored along the way 
  • Keep a log of where the data has been accessed along the way
  • Keep records of other vital metadata. 

Most importantly this visualization is not just about tracking your data but also understanding the intricate processes and dependencies involved in data flow, whether cloud-based or within a physical premises.

However, data lineage is more than just a documentation of data flows and paper trails. It’s a comprehensive map of all the direct and indirect relationships between data entities within an organization. This detailed mapping is the cornerstone of a modern data stack, providing complete visibility and helping to identify and address data blind spots. It plays a pivotal role in ensuring ethical, compliant, and efficient data management. 

By understanding these dependencies and interactions within your data systems, data lineage allows for more informed decision-making. It helps you to assess the impact of changes in data algorithms on various reports and forecasts (note – Could Solidatus illustrate this point with an example?). It can assist you in understanding the usage and purpose of regulated data and provide valuable guidance when selecting optimal test cases for new database applications, and strategizing cloud migration without jeopardizing the existing systems that you’ve worked to maintain.

Simply put, data lineage empowers organizations to fully utilize their data and unlock its potential. Utilizing it successfully can lead to:

  • Enhanced infrastructure optimisation 
  • Better operational efficiency
  • Minimized risk 

 There are all things that align perfectly with Solidatus’ commitment to intelligent data management and discovery.

 

Why is Data Lineage Important?

Reliable, automated data lineage is crucial in ensuring the accuracy and trustworthiness of an organization’s data, a cornerstone in modern data management.

What are the two different types of data lineage?

Data lineage, a key component in modern data management, is categorized into two distinct types: business lineage and technical lineage. Each type serves a unique purpose and caters to different aspects of data management, aligning with the comprehensive solutions offered by Solidatus.

Business lineage

This form of lineage is designed for simplicity and accessibility, primarily catering to business analysts. It provides a high-level overview, illustrating the journey of data from its source to the final report. This summary view is crucial for analysts who need to verify the reliability of their data sources without getting entangled in the intricate details of every data alteration. Business lineage is about offering a clear, interactive map that traces data flows, ensuring that the data used is dependable and sourced correctly.

Technical lineage

In contrast, technical lineage delves into the finer details, tailored for IT professionals and data architects. It offers an in-depth view of data transformations and allows users to drill down to specific details like table, column, and query-level lineage. This detailed perspective is essential for navigating complex data pipelines and understanding the nuances of data transformations. Technical lineage provides a comprehensive view, enabling IT experts to manage and architect data with precision.
 
When combined, business and technical lineage offer an integrated view of an organization’s data landscape. This dual approach ensures that data citizens across various departments and roles have the necessary tools and insights to make accurate and informed business decisions. By integrating both business and technical perspectives, data lineage tools facilitate a more nuanced and effective approach to data management, aligning with Solidatus’s vision of empowering organizations through intelligent data solutions.
 
 

Data lineage best practices

Implementing and planning data lineage requires a strategic approach to ensure effective data management, aligning with the intelligent solutions provided by Solidatus.

Here are some best practices to consider:

Embrace automation for data lineage extraction

In today’s fast-paced and ever-changing data environment, relying on manual methods like Excel for capturing data lineage is outdated. Automation is key to keeping up with the dynamic nature of data, ensuring that lineage is captured accurately and efficiently.

Incorporate metadata sources in data lineage

Data lineage should include metadata from various sources such as ETL software, BI tools, relational database management systems, modelling tools, and custom applications. This metadata is crucial for a comprehensive understanding of your data’s journey from its origin to its destination.

Engage metadata source owners

Collaboration with the owners of metadata sources is essential. These individuals have the best understanding of the metadata’s timeliness, accuracy, and relevance. Their involvement is crucial in verifying and ensuring the integrity of data lineage.

Plan for progressive metadata and data lineage extraction

Mapping out the data’s path through your systems is the first step. Following this, progressively extract metadata and data lineage from each system. This methodical approach simplifies the mapping of connections, relationships, and dependencies within and among systems.

Validate lineage in stages

Begin with validating high-level connections between systems, then progressively drill down into datasets and data elements. The final step should be the validation of transformation-level documentation. This staged approach ensures thoroughness and accuracy in lineage validation.

Utilize an enterprise-class data catalog 

For comprehensive, end-to-end lineage that spans both cloud and on-premises environments, an enterprise-class data catalog is indispensable. Choose a catalog that can automatically integrate lineage from all enterprise sources. This should include capabilities for extracting and inferring lineage from metadata, ensuring a granular and complete lineage view.
