SCDJWS points to remember

Today I am starting to read RMH book.
What is web service?

A Web service is a software application that conforms to the Web Service Interoperability Organization's Basic Profile 1.0.

The main purpose of Web service technologies is to allow applications on different platforms to exchange business data. Web service technologies are used for Application-to-Application (A2A) integration or Business-to-Business (B2B) communication. A2A refers to disparate applications within a single organization communicating and exchanging data—A2A is also known as Enterprise Application Integration (EAI). B2B refers to multiple organizations, typically business partners, exchanging data. Web service technologies today are used mostly in A2A/EAI settings, but they are also seeing growth in the B2B arena.

Examination point of versions of the web service standards.
