Okay, we have our definition of Data Lake, so ... What is Data Warehouse? Isn't it the same thing?
No...
Data Warehouse, is where we will store structured data that has already been processed for a particular function. While at the Data Lake, we have all kinds of data (raw or not) available for use.
Look at this image, how cool!:
Visualizing things makes it easier to understand, right? By the way, later we will talk about Data Visualization, something very interesting!
That's it for today!
Thanks for the visit!
