# UDC integration

The Universal Data Controller (UDC) in the Grassfish system is responsible for the distribution of data used by spots. Examples for this are weather data, news, room booking data etc. which are graphically displayed in spots.

Generally, UDC data is provided via web services. There is also a JavaScript abstraction implementation called UdcConnector, which is helpful for requesting data as well as testing purposes. For more information, see [HTML Spot UDC Connector](https://docs.grassfish.com/grassfish/docs/html-spot-udc-connector).
