Enterprise Service Bus
A "middleware" application whose role is to provide interoperability between different communication protocols. For example, it's not uncommon for a company to receive incoming ASCII-delimited orders through older protocols such as FTP. An ESB can "lift" that order from the FTP site, transform it into XML, and then submit internally to a web service for consumption and processing.
BPM
Business Process Management - type of composite services; complex or workflow-type business processes. (BPM) is a set of technologies that enables a company to build, usually through visual flow steps, executable processes that span across multiple organizations or systems. The fundamental impetus behind BPM is cost savings and improved business agility.
REST
Representational State Transfer
SOA
Service-Oriented Architecture is an IT strategy that organizes the discrete functions contained in enterprise applications into interoperable, standards-based services that can be combined and reused quickly to meet business needs.
SOAP
Simple Object Access Protocol
WSDL
Web Services Description Language, used to create the XML document that describes the tasks performed by various web services.
Central Theme of SOA
encourages loosely coupled services
Web Service
self- describing, self- contained application that provides some business functionality through an Internet connection.
