Why do we need Web Services?



Why do we need Web Services?..

Answer / amey

We have a number of heterogeneous technologies available on
internet. The demand for reusable components across
platforms and programming languages are high. Most of the
components have the limitation that they can't share or
exchange data across different platforms, they are mostly
language specific or platform specific. The technologies
like COM, RMI, CORBA etc. contributed best to fulfill
requirements to some extent, but components result from
these said technologies are mostly either language specific
or platform specific.

To avoid above problem, we need to have web services.
Through web services we have overcome the problem of
interoperability between languages and platforms. Web
services uses SOAP as transport protocol which uses a text
based messaging model, i.e. XML to communicate between
disparate systems.
