They are usually structured, meaning that data is loaded, extracted and transformed (ELT) to conform to pre-defined schemas before it’s stored. This allows you to run queries against them much easier than running them directly against source systems that are operational.
The traditional warehouses on-premises require expensive hardware and software in order to be hosted. They have limited storage compared to computing power and must continually discard old data to make space for the newest data.
