Web services are self-contained, self-describing, modular applications that can be published, located, and invoked across the Web. They perform functions that range from simple requests to complicated business processes. Major vendors such as Microsoft and IBM are scurrying to market the development tools, applications, and platforms designed to let you access these services.
Web services were conceived to provide fast, efficient interactions that don't require information to be reentered or manipulated to be processed by complex, multistep systems. By automating and encapsulating certain types of services, companies can create a more intimate and tighter relationship with trading partners, vendors, and customers and exchange information more quickly.
Automation is key; Web services are designed to allow different types of processes to act together and use the same data in a standard manner.
