What is the difference between a data lake and a data warehouse?
When first getting into this space there might be some confusion between data lakes and data warehouses. That is fairly common.
The main difference between a data lake and a data warehouse is specificity and structure.
A data lake is a formless blob of information, it is a pool of knowledge where we try to capture any relevant data from our business so that we can perform analytics on it.
A data warehouse is a specialized tool that allows you to perform analysis on a portion of that data, so you can make meaningful decisions from it. Generally, it is a subset of the data from the data lake with a specialized purpose. Your data warehouse Is an optimized database that is dealing with normalized, transformed, and cleaned-up versions of the data from the data lake.
