SQL databases, Spreadsheets

Semi-structured Data

Data with some structure but not as strict.

JSON, XML

Unstructured Data

Data with no set format, harder to study.

Text files, Multimedia

A lakehouse can work with all three types. A traditional data warehouse usually only works with the first two. If your business uses many kinds of data, a lakehouse gives you more choices.

Architecture

The way each system is built changes how you use your data. In a lakehouse, you have one storage layer for everything. You can keep all your data in one spot for different jobs. Storage and computing are separate, so you can make each bigger when you need. You can run batch and streaming jobs, which helps with real-time data.

A traditional data warehouse has a stricter setup. It puts data in tables and uses batch jobs. You often need to move data through steps before you can study it. This works well for regular reports but can be slow if your data changes a lot.

Here is a table that shows the main differences:
