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.

Design Goals

According to the web site of The Developers the goals were

• rapid application development: avoid the programming of standard stuff like table views, standard action buttons, menus etc.
• cross platform development: any Protogrid application runs as is on all platforms supported by Protogrid (at present: several web browsers and iOS)
• multi language support: any Protogrid application can be translated within hours to any other language by a person with knowledge of the source and target language
• ability to run off-line: any Protogrid application must be able to run off-line on a mobile device offering the full set of functionality

Features

• Portability: Protogrid applications are supposed to be portable to all Protogrid clients without additional programming effort.
• Touch screen optimization: Protogrid applications are optimized for touch screens
• Support for Responsive Design: Protogrid applications run on a range of screens starting from smartphones, tablets unto large screens. The fields and columns are automatically distributed.
• Cloud based: The Protogrid back end server resides in a public or private cloud¨
• Web enabled apps: Any Protogrid application runs in a browser as web app
• Multi language support: As well Protogrid as Protogrid application allows for multi language support
• Support for off-line operations: A Protogrid application runs also without internet access. Data is synchronized automatically as soon as internet connection is available.
• Data types supported: Text, Date with time, Number, Relations and Tables referencing other records.

Technologies used
