The more I think about it, the more I am convinced that this could offer endless possibilities for others to hook onto Wix Code. I would like to develop an application that lets one define a combination of user-interface and database elements. Once done, the thing generates the collection schema, the user interface, the data binding and the code.
One thing would be paramount: in order to be able to monetize, we would need a possibility to export all and the client a possibility to import.
Think about it: clean, running code, in backend modules for data, maybe a API to write a Zap, a possibility for row locking (semaphores), 1-to-n input screens (purchase orders, time and billing), anything would be possible for us to write.
Done this before for ASP and SQL-server and it saves user an enormous amount of time and aggravation piecing this together by himself and you, Wix, a lot of support.
