Transactional systems.

Web services is a distributed programming architecture that solves Enterprise Application
Integration (EAI) hurdles that other programming models cannot. It enables programs to
communicate with one another using a text-based, platform- and language-independent
message format called XML.

Coupled with a platform and language independent messaging protocol called SOAP (Simple
Object Access Protocol), XML enables application development and integration by assembling
previously built components from multiple web services.
