Electronic Data Interchange (EDI) is an established form of e-commerce, which has traditionally always taken place over the proprietary networks. Many companies are migrating towards adoption of EDI for its convenience and accessibility and fast turnaround. Many efforts are being undertaken for reducing the cost of EDI so that even smaller companies can adopt it. One way of reducing the cost of EDI, and making it more accessible to smaller companies, is to commensurate EDI standards to the Internet, various systems are currently competing to offer this service.

Electronic Data Processing (EDP) Systems are the software designed for processing the raw data through computers. Through these systems the computers work with the data and manipulate it to uncover relationships with little intrinsic values and between different variables. Declarative and summary reports can be produced using electronic data processing.
