Build Zoho Projects-Connected Apps in Mendix

Mendix is a high-productivity app platform that allows you to build and maintain both mobile and web applications at-scale. When paired with CData Connect Cloud, Mendix provides instant, cloud-to-cloud access to Zoho Projects data for applications. This article demonstrates how to connect to a CData Connect Cloud data source from within Mendix.
