Lineage is represented visually to show data moving from source to destination including how the data was transformed. Technical lineage shows facts, a flow of how data moves and transforms between systems, tables and columns. To give a few real-life examples of the challenge, here are some reasonable questions that can be asked over time that require reliable data lineage: Unfortunately, many times the answer to these real-life questions and scenarios is that people just have to do their best to operate in environments where much is left to guesswork as opposed to precise execution and understandings.

It explains the different processes involved in the data flow and their dependencies. In some cases, it can miss connections between datasets, especially if the data processing logic is hidden in the programming code and is not apparent in human-readable metadata. A data lineage is essentially a map that can provide information such as: When the data was created and if alterations were made What information the data contains How the data is being used Where the data originated from Who used the data, and approved and actioned the steps in the lifecycle When you run a query, a report, or do analysis, the data comes from the warehouse.
