Notes:

You have learned about the technologies that are used in Web Services. Let’s take a moment to review each:
SOAP – SOAP is the most basic building block used to build Web Services. It is a function invocation protocol that uses XML to describe its data.
WSDL – Web Services Description Language is the specification that describes a service’s interface. It is an interface definition language.
UDDI – UDDI is a searchable registry of Web Services.
WSFL and XLANG – Languages that describe work flow (a.k.a. orchestration, composition). WSFL is from IBM; XLANG is from Microsoft. BPEL4WS is a unifying specification for WSFL and XLANG.
