Short for Service Oriented Business Applications, SOBA represents the expected end state of the Service-Oriented Architecture (SOA) vision. That is, SOBAs are business applications that function in a service-oriented environment to provide discrete units of business-level functionality through well-defined service contracts (keeping the services encapsulated and self-contained). Within the SOA model these services can be dynamically combined as needed by the business.
