SOA concept in business world

In the following paragraphs I am addressing one of Dr. Schwarz' papers [1] about "Service-Oriented Architecture" (SOA).

  SOA in IT world concentrates on functionality developments of services without large scale changes in applications [1]. For instance if a part of a service is not functioning properly one may alter just the related software to correct the whole structure instead of changing the whole application. This approach makes IT more closer to its partners in the firm and provide enough tool for business unit to deliver its services in the best way [1]. In IT community now SOA tries to make innovation by putting tools in hands of the end users to create and combine different services and make a new service [1].

   SOA is an alternative for prototypes like Application Program Interface, Function cells, and etc [1]. SOA is a set of open standards which defines what is the objective service and how we can communicate with that, and how to find and use it [1]. In brief, SOA make a huge application into smaller blocks and encapsulate all related  data and services in this "Black box", then malfunctioning of this box results in replacement of the black box with out concerning about the software.
 
   SOA now is becoming a part of business plan for many of companies and many firms are adopting this concept from IT and becoming a Service Oriented Enterprise [1].

More on this topic is coming soon .....
