it's a real term but it's not a useful term to engineers. there is no such thing as a "data lake system". there are databases, filesystems, object stores, etc. where the term 'data lake' is actually useful is in describing a logical system that holds data pulled from all over the company together into one place to non-technical people. inevitably the actual implementation will be a dozen or more different cobbled together systems and technologies, but if you try to explain that to your finance team their eyes will glaze over immediately, hence the need for the term 'data lake'.

Great explanation. It’s C-level terminology.

You don’t really build a data lake, you just end up with one.
