I have been finding out how businesses use IT and how it changes their businesses. I have found an open source software package called OpenERP that offers many of the features businesses need. The main company OpenERP S.A. is interested in OpenERP being used in schools and universities to allow students an incite into both the IT systems and business processes used today.
They also have a project using the Raspberry Pi to power EPOS systems. It’s available for backing on Indiegogo. I’ve backed it as I think it will be interesting to see affordable open source solutions to this.
