How to connect to Third Party database directly in Lithium without REST API?

sismail786- There is no other way to fetch or store data from third party sever without using REST API's .

To achieve this in lithium you need to create an endpoint and use http.client.request for the calls. You can get more info about the http.client.request here.

The other way to do this , directly hit a  jQuery Ajax call to the third party server.
