This represents data sources that have been validated to work using the available translators and connectors. However, this does not preclude a new data source from working. It can be as easy as extending an existing translator, to creating a new translator using the Translator Development extensions.

Take a look at the list of Translators that are used as the bridge between Teiid and the external system.
