Unlike some of the other data integration models, Service Data Objects don't stop at data abstraction. The Service Data Objects framework also incorporates a good number of J2EE patterns and best practices. SDO supports a disconnected programming model. The SDO programming model prescribes patterns of usage that allow clean separation of each of these concerns.

Put simply, Service Data Objects is a framework for data application development, which includes an architecture and API. Service Data Objects simplify the J2EE data programming model and abstract data in a service oriented architecture (SOA). SDO unifies data application development, supports, and integrates XML. Service Data Objects incorporate J2EE patterns and best practices.
