Metadata import

You use the enterprise service discovery wizard in the WebSphere(R) Adapter for JDBC to discover objects in a database and to generate business objects from the selected objects. Enterprise service discovery support also generates the service constructs that enable the adapter to run as a Service Component Architecture (SCA) component.

Objects from which business objects can be created include tables, views, stored procedures, and synonyms/nicknames. The adapter enables you to discover the objects by generating a list of all the schemas in the database. Within each schema are lists of tables, views, stored procedures, and synonyms/nicknames that you can select and request the enterprise service discovery wizard to generate the corresponding business objects. The wizard analyzes the metadata of objects and generates attributes in the business object. The attributes are generated based on the column names for all database objects. To summarize its functions, the enterprise service discovery wizard:
  • Generates a business object corresponding to a database object.
  • Generates properties in the business object corresponding to the properties in the database object.
  • Sets application-specific information on the business object.
  • Provides service descriptions (inbound and outbound) that are used to generate the import, export and Web Services Description Language (WSDL) files.

This figure illustrates the interaction of the enterprise service discovery wizard, the JDBC enterprise service discovery, and the JDBC enterprise information system (EIS) to discover database objects, gather metadata, and generate business objects and service metadata.
