expose business logic beyond the firewall. Through Web services
companies can encapsulate existing business processes, publish them as
services, search for and subscribe to other services, and exchange
information throughout and beyond the enterprise. Web services will
enable application-to-application e-marketplace interaction, removing
the inefficiencies of human intervention.
The key benefits of Web Services are:
1. SOFTWARE AS A SERVICE
As opposed to packaged products, Web Services can be delivered and
paid for as streams of services and allow ubiquitous access from any
platform. Web services allow for encapsulation. Components can be
isolated such that only the business-level services are exposed. This
results in decoupling between components and more stable and flexible
systems.
2. DYNAMIC BUSINESS INTEROPERABILITY
New business partnerships can be constructed dynamically and
automatically since Web Services ensure complete interoperability
between systems.
3. ACCESSIBILITY
Business services can be completely decentralized and distributed over
the Internet and accessed by a wide variety of communications devices
4. EFFICIENCIES
Businesses can be released from the burden of complex, slow and
expensive software development and focus instead on value added and
mission critical tasks. Web
services constructed from applications meant for internal use can be
easily exposed for external use without changing code. Incremental
development using Web services is natural and easy and since Web
Services are declared and implemented in a human readable format there
is easier bug tracking and fixing. The overall result is risk
reduction and more efficient deployability.
5. UNIVERSALLY AGREED SPECIFICATIONS
Web Services are based on universally agreed specifications for
structured data exchange, messaging, discovery of services, interface
description, and business process orchestration.
6. LEGACY INTEGRATION
Greater agility and flexibility from increased integration between
legacy systems
7. NEW MARKET OPPORTUNITIES
There will be greater feasibility to the dynamic enterprise and
dynamic value chain businesses
If you are using an XML Web Service, you can assume the results will be returned as some kind of XML document, that's explicitly structured and self-describing.
