Data descriptions

Data descriptions are some of the service constructs that the enterprise service discovery process generates to enable the adapter to run as a Service Component Architecture (SCA) component.

The data description includes a definition of the structure and content of adapter business objects that is passed between the client application and the adapter at run time. The data description enables the client application to create the proper data objects for requests, and to interpret the data objects returned as responses. The data description generated from the database components is represented as an XML schema.
  • The business object maps to a complex type definition.
  • The attributes of the business object map to element type definitions.
  • The application-specific information for the business object is contained in annotations at the complex type.
  • The application-specific information for each property in the business object is contained in annotations for the element types.
Note: The template for the application-specific properties for the business object and the attribute level are defined in the metadata schema for the JDBC adapter. The name of the schema file is JDBCASI.xsd. The generated schema file has a reference to this template in its annotations.
