Data Lineage Approaches

The biggest problem I've seen with data lineage product so far is the inability to decode or unravel user defined functions. That's why our idea is our approach to data lineage is a different one that says do this where you can. But the end to end you will not reach that way, but you get it through the way. So we have another question from Adam: The biggest problem I'm seeing with data lineage products so far isthe inability to decode and unravel user defined function. What is your take on that? No, I 100% agree, and I feared that this is an unsolvable problem in the end because there's always the human factor to it.
