Every data team has to build an ecosystem that sustains the data, the users and the use of the data itself. This data ecosystem comes with its own challenges during the building phase as well as during its maintenance and enhancement. One of the challenges is the need for a mechanism for data to be reliably monitored, associated with a purpose and having the ability to be traced and retrieved. This is the foundation of the idea of Data Lineage.

It is important to understand the role of data lineage in an organization and how it can impact the data ecosystem. This talk focuses on the why and the how behind having a mechanism for data lineage in your organization. The Why includes understanding the exact need for lineage by examining the use cases it would power. While the How talks about the requirements and design that are needed to build such a mechanism.

After covering the philosophy behind building data lineage, there will also be a discussion of what tools can be readily used versus the idea of building something on your own.
