Which language is best to build an erp?

Question

I want to make certain software like billing software, school management system etc. which language is the best to learn and Implement

Answer 1

Fastest working implementation you can get will be with HTML/JS/PHP + SQL (in my opinion). You can code basics of your system in a day or two with it. Other languages will be good too but it will be somewhat harder and time consuming, especially if you want to use C++.

Answer 2

I think php will not allow features like license key for activation and hiding the code from client

Answer 3

You are right, if you want to create pure desktop applications without web features - PHP is not your instrument. Then you can consider Java or C#, both of this languages are used in business programming often. C++ used more in game development. Can't say anything about Python and Ruby, hasn't seen a lot of vacancies with requirements of this languages.
