For the moment, We are developing a POS system. The first prototype is beeing developed under Windev(1), but, I would like to move to opensource
I have developped a POS system under Windev. Developping in Haskell for this project was unfortunately not an option for me; however maybe I can help you with a few answers : - There are libraries for database access, for example HDBC or Takusen. I have used HDBC-mysql with no problems so far - We accessed a serial display, a ticket printer and a cash drawer using OPOS drivers which are unfortunately a Windows only thing. I don't think there's an OPOS binding for Haskell, so you're left with two options: * develop such a binding yourself, * find a way to access the devices directly. - There's no problem to code web services in Haskell. There's many networking libraries, web frameworks, etc. - Windev has many shortcomings especially compared to Haskell, but one thing it's good at, is quickly doing user interfaces. In Haskell, the UI will IMHO require more work in Haskell. That being said, I've never designed large UIs in Haskell, so maybe with experience it
Then, my main question is: I know (suppose), with Haskell you can develop whath you want, and I readed Scala is a good option, but I don't like the idea of depend of JVM, and Haskell do native executables. Is worth the effort for this type of applications? There are libs for this things? It's easy to maintain large projects?
Sorry for my english and lack of knowledge :S
PD: I come from a Delphi and Smalltalk background.
