Hi Rechard, I am using Microsoft SQL Server to create the database for the cafeteria management system. If you have a link which will help me to refer and to get some tutorial, please, give me the link. Thank you for your help.

Dear Richard MacCutchan, I would like to say thank you for your response. But, I need some example that how to reduce and count if you have any link for the database tutorials which matches the question I am asking. Thank you Very much.

Hi My name is Teame. I want to develop a cafeteria management system using C#. But, I want to compose the consumption and to reduce from master inputs balance. For example, when I want to make an output called pizza, I have to use a potato, tomato, oil, green paper, and so on inputs. Then the inputs I have used should be reduced from the master inputs balance and will made as an output product called Pizza. So, please, help me to how to reduce the input consumption automatically when the waiter orders a Pizza using C#. I would like to say thank you for your support.
