Data lake
A large store for keeping raw data in many formats until it is needed
What's it for?
Provides a large, flexible place to keep different kinds of data until they are needed.
For example…
IT lands website click logs, emails, and export files in one place so analysts can explore them later
A retailer keeps raw clickstream files, support logs and sales extracts in a data lake before deciding which combinations are useful for analysis.
Think of it like…
A storage yard where raw materials are kept until they are needed for sorting and processing
