Did a quick search because I was curious, this was the first result:

> Data lakes and data warehouses are both widely used for storing big data, but they are not interchangeable terms. A data lake is a vast pool of raw data, the purpose for which is not yet defined. A data warehouse is a repository for structured, filtered data that has already been processed for a specific purpose.

In my defense, when I did my googling a while back, it was specifically about data lakes, not the comparison. :)
