The Road to SOAP
• As far back as the 1960s, companies turned to computer automation to reduce the paperwork burden associated with purchase orders, bills of lading, invoices, shipping orders, and payments.
• Driven by a need to standardize the exchange of data between companies doing business with each other, in 1979 the American National Standards Institute (ANSI) chartered the Accredited Standards Committee X12 (ASC X12) group to develop uniform standards for interindustry electronic interchange of business transactions.
• The result was a collection of standards known as the Electronic Data Interchange, better known today as EDI.
• As Figure shows, EDI is built around point-to-point networks that require partners to use software that implements EDI's data and messaging specifications.
• It is expensive both to develop and to maintain. In addition, once an EDI system is in place, changes must be agreed upon and implemented by all participants.
• For medium- and small-size businesses, EDI's cost is prohibitive.
• There will always be a need for a WAN wrapper, a network over which to deliver the data.
• Using the Internet as the global WAN wrapper and XML as the data format, the problem of data distribution is greatly simplified. The missing piece is how to get the data from point A to point B, which leads us to HTTP.
