The purpose of a service interface in a SOA (Service-Oriented Architecture) is to define the technical definition of the contract between the service provider and the service consumer. It contains the signatures of the service operations, including their input and output parameters, as well as any exceptions that may occur. The service interface acts as a communication channel, allowing the service consumer to interact with the service provider by invoking the defined operations. It helps to establish a clear understanding of how the service should be used and what data should be exchanged.
