The difference between a data lake and a data warehouse is:
Data warehouses typically contain live production data. Data lakes contain a
copy of the production data.
Data lakes store data in 'raw' form (i.e. the original form). Data warehouses
typically store data that has been extracted, transformed and loaded (ETL) for
purposes of performing analysis.
Data warehouses contain data from multiple sources and data lakes collect data
from only a single source.
Data lakes and data warehouses are the same. The terms are used
interchangeably.
