What is "protogrid"

Protogrid is an integrated application development solution for the development and operations of information systems. It comprises a server and a client. The client is available for web browsers and iOS. Protogrid includes a development interface that allows for development of applications using rapid application development methods. On the back end there are NoSQL databases like CouchDB. Business logic can be added to a Protogrid application using Javascript. With version 1.1 which was released in May 2016 a json API providing external access was introduced.
