Service Data Objects (SDO) is a framework for data application development that provides an architecture and application programming interfaces (API). WAS v8.5 includes an implementation of SDO 2.1.1 interfaces. After the product is installed and SDO is enabled, SDO 2.1.1 becomes the default SDO implementation when programming with SCA or SDO interfaces.
transition: For backwards compatibility, deprecated functions like JDBMediator continue to use previous SDO implementations described in "Data access with Service DataObjects, API versions 1.0 and 2.01". Otherwise, SDO clients are bound to the SDO 2.1.1 implementation.
SDO 2.1.1 is a Java standard approved by the Java Community Process (JSR 235). For details on SDO 2.1.1, refer to the JSR 235 specification.
WAS v8.5 implementation complies with JSR 235, and provides some implementation-specific extensions. These extensions align with the latest direction of the SDO 3.0 specification under development at OASIS. Although there is no guarantee, these 3.0 API extensions will likely be officially standardized in future versions of SDO. Table 1 lists the 3.0 API extensions included in the product.

- Create and accessing SDO HelperContext objects
The SCA implementation complies with Service Data Objects (SDO) 2.1.1 (JSR 235), and provides some implementation-specific extensions. These extensions align with the latest direction of the OASIS SDO 3.0 specification under development. One of the extensions introduces an API for creating and managing HelperContext objects, which are in the SDO class and HelperContextFactory interface.- Use SDO 2.1.1 in SCA applications
The SCA implementation complies with Service Data Objects (SDO) 2.1.1 (JSR 235). We can use SDO 2.1.1 in your SCA applications.
