# Flux documentation

Flux is an open source functional data scripting language designed for querying, analyzing, and acting on data. Flux supports multiple data source types, including:

-   Time series databases (such as [InfluxDB](/flux/v0/query-data/influxdb/))
-   [Relational SQL databases](/flux/v0/query-data/sql/) (such as [MySQL](/flux/v0/query-data/sql/mysql/) and [PostgreSQL](/flux/v0/query-data/sql/postgresql/))
-   [CSV](/flux/v0/query-data/csv/)

Flux unifies code for querying, processing, writing, and acting on data into a single syntax. The language is designed to be usable, readable, flexible, composable, testable, contributable, and shareable.
