What is Data Lineage?

I get questions like this a lot:

• Where did this data come from?
• How do I know I can trust the source?
• What types of QA checks were applied to this data?

Data lineage is such a chronic issue in data engineering. This blog post from Airbyte gives a good overview & mentions some interesting products/projects that can maybe help out with data lineage.

Unfortunately, I have limited flexibility to purchase or install tools for this in my current role. Anyone rolled their own solution for this?
