Service-oriented design principles

The goal of service-oriented design is to divide the business system into independent computing units, like CPUs. These independent computing units are services, and most of them are used to implement services, another service is used to assemble these business services, which is a workflow service.

The core value of a service is autonomy and autonomy. A service is like an operational unit. This is a metaphor for a service. It indicates that the service has its own memory, cache, and storage,AlgorithmImplementation, etc. Its external interface has two layers. The first is what operation is provided by the computing unit (it is like what service is provided by the Service ), the second is the input data and possible output data required for this operation (it is like the input and output of the Service ).
