# Working with Datasets
Datasets are abstractions of geospatial and non-geospatial data. They are the core of Flo.w Engine's services.
Datasets can be:
- Created by uploading data to Flo.w engine.
- Queried using SQL-like query definitions.
- Used to generate vector map tiles.
Datasets are stored in an per-application database. Flo.w Engine supports pluggable database drivers for a variety of backing storage. By default, PostgreSQL/PostGIS is used.
