The framework in order to develop the softness and the quick system by the fact that the application - - software service which has the function which releases the interface in order to utilize with respect to network, becomes independent is combined. For example in the accounting system, "consumer tax calculation" and "foreign currency calculation" etc. respectively become one software service.
To make available combining software service, as one system, structure of the management in order to guarantee and the security which the message which is formed from each service sending and receiving are done It places software service on these layers, following to the functional request which the end user seeks, it keeps constructing the system.
As the merit of SBA, by the fact that existing system property is reused, you can list the fact that the new system can be developed quickly. However this merit is enjoyed, actual business process is analyzed, some process has overlapped, if in addition it is some kind of function, it is necessary to ascertain whether it can reuse. It is important to advance mounting the system on the basis of this analysis result, to keep accumulating as future reuse property.
