Q&A

Q.

What is the advantage of the web service model over conventional client-server programming?

A.

The web service model is design to integrate standard components that are already present on most networks, such as web server and web browser applications.

Q.

Why is the web service model based on XML instead of HTML?

A.

HMTL is predefined collection of tags intended specifically as a markup language for web pages. XML has nearly unlimited capacity for defining new elements and assigning values to variables.

Q.

Considering that countless vendors all have their own languages and components for supporting web services, what is the benefit of uniform standards like SOAP and WSDL?

A.

Standards like SOAP and WSDL provide a common format so that components written for different vendor environments can easily interact.
