Which language is better to implement a small supermarket inventory management system in, c++ or java (both of which I'd have to relearn, having a basic knowledge of c)?

ERP is either java or C#. Rarely is it written in C++ unless he has nothing better to do. (Terminal is another matter)

And in fact the large ERP with java majority

Small and medium-sized with C# majority, C# development speed, collect money naturally faster, the money back fast

To the door is the foreground C#, backend java, java is after all, cross-platform, the requirements of the server to be high unix/linux C# on the stupid, so the background is generally java, the foreground depends on the situation

Then you judge for yourself.

ERP implementation does not seem to care what language you write it. People wrote the program, test finished, sold to the customer, signed the contract, is the implementation of the customer to install, what problems, the customer will contact, the problem feedback, development and modification, you then go to the implementation of upgrades and so on, do not need you to understand the program internal things.

This type of after-sales, you need to understand the product business, able to answer customer questions and so on
