In today’s world, the need for agile, reusable and self-contained applications is at its

peak. A web service can be described as a reusable software component that can be

published and used by another software over the internet. The goal here is to provide an

easy mechanism for applications to locate a service that provides the desired function

and then implement it to achieve its goal.

Many advantages are associated

with the use of web services. In

essence, the main advantage web

services have over regular web

applications lies in its interopera-

ble nature, that is web services can

communicate with different appli-

cations to provide a higher business

level functionality despite the vari-

ous underlying technologies of each

application. Web services are hard-

ware, programming language, and

operating system independent. This

independence is due to the use of

the standardized XML technologies.

Such technologies include SOAP,

WSDL, and UDDI. Furthermore, web

services offer additional advantages

including reduced costs, application

integration, and data integration.

Several technologies support the process

involved in the use of web services. These tech-

nologies are summarized below:
