This document discusses electronic data interchange (EDI), which allows for the transfer of data between computer systems without human intervention through standardized formatting. It works by arranging data elements like prices and product numbers separated by delimiters into messages. EDI provides benefits like reduced costs, increased accuracy, improved efficiency and speed by freeing up staff time. However, it also faces disadvantages like difficulties with non-standardized systems, security issues, and the need for specialist onboarding. The future of EDI depends on adapting to new technologies like cloud computing to overcome current challenges.
