<h2>Abstract</h2>
<p>The term Web Services describes an application of XML for exposing
application functionality to disparate clients via the Web. This paradigm
provides access to entire applications, modules, objects, functions,
and methods via HTTP and other transport protocols. Web Services are
inherently platform- and programming-language independent. Services can be
developed in one language and consumed in another; this holds true
irrespective of client or server host operating system combinations.</p>
<p>A collection of core XML-based specifications and standards work in
concert to fulfill the Web services value proposition. These standards
include:</p>
<ul>
<li> SOAP - XML notation that describes how messages are assembled and
transmitted over HTTP between services and service consumers.</li>
<li> WSDL - XML notation for describing SOAP services. </li>
<li> UDDI - Application of the SOAP protocol for registering and
publishing information about organizations, contacts within organizations,
and Web Services that these organizations have chosen to expose to the
public.</li>
</ul>
<p>
Virtuoso enables stored procedures to be exposed as Web services that
are consumable by any Web services-aware development tool,
application, or environment. The stored procedures exposed by Virtuoso
may be native stored procedures, or may be hosted in any third-party
database that supports stored procedures, and is accessible via an
ODBC or JDBC driver. In Virtuoso, exposing stored procedures as Web
services does not require any programming effort. You simply identify
the stored procedures to be exposed using the Virtuoso Administrative
Interface.
</p>
<p>
This feature is immensely valuable in situations where organizations
are seeking to transform time-tested stored procedures into Web
Services without having to upgrade or change databases or host
operating systems. In modern enterprises, such stored procedures
drive mission-critical solutions; Virtuoso's approach to Web services
enables you to maximize current investment while minimizing the need
for rework.
