Can you connect an SQL database to a web application in ArcGIS Online's Web AppBuilder?

[BryanHuebner]

I am currently working on putting together a basic application in web appbuilder. And I am wondering if I can make a connection to our SQL database to make the application data dynamic.

Bryan,

   The JS API (which WAB uses under the hood) does not have the ability to connect to a SQL database directly. It use ArcGIS Server to communicate with GeoDatabases. Your other possibility is to develop a RESTful Web Service in .Net, then that web service can be used by an esriRequest to gain access to your database.

Thank you Robert. That is exactly the information I was looking for.
