Web services better than non-serviced . Net Component

suppose there is a manufacturer that produces a wide range of products and it has several dealers in each city/state
each dealer has his own shop web site that displays some kind of product information produced by the manufacturer. So in this case, the manufacturer would host a web service that provides the product information which is consumed by several dealers in their own web sites one built in java, other on .net and so on.
So the change in product information,specification, new products etc is provided to all the dealers avoiding manual updation

Hi Neha,

              see,service oriented  architecture have their own area of benifit over nonserviced......

1.service oriented architecture provide location independence.Therefore, an organization has the flexibility to move services to different machines, or to move a service to an external provider
Services need not be at a particular system or particular network.

2.one more benifit of service oriented architecture is--Support for Multiple Client Types:-
  companies may use multiple clients and multiple client types to access a service. A PDA using J2ME may access a service via HTTP, and a SWING client may access the same service via RMI. Since the layers are split into client and service layers, different client types are easier to implement.

3.so,A service layer takes little extra effort in the beginning of a project, but the benefits are  in the longtime.

i hope these points solve your query.
Thanx,
Pravin.
