Web services usually refer to services implemented and deployed in middle-tier application servers. However, in heterogeneous and disconnected environments, there is an increasing need to access stored procedures, as well as data and metadata, through Web services interfaces.

The Database Web services technology is a database approach to Web services. It works in the following two directions:. Conversely, consuming external Web services from the database, together with integration with the SQL engine, enables Enterprise Information Integration. Web Services use industry-standard mechanisms to provide easy access to remote content and applications, regardless of the platform and location of the provider and implementation and data format.

Client applications can query and retrieve data from Oracle Database and call stored procedures using standard Web service protocols. There is no dependency on Oracle-specific database connectivity protocols.

Java classes implementing data-related services can be migrated between the middle tier and the database. Java portability results in database independence. Leverages warehousing or business intelligence queries, data monitoring queries, and any predefined SQL statements as Web services.

Offers secure, persistent, transactional, and scalable logging, auditing, and tracking operations implemented through SQL DML, as Web services. The Simple Object Access Protocol SOAP provides a standard way for applications to use the internet to exchange information and access services that implement the business logic.

SOAP 1. The following JPublisher features support Web services call-ins to the code running in Oracle Database:. You can extend the storage, indexing, and searching capabilities of a relational database to include semistructured and nonstructured data, including Web services, in addition to enabling federated data.

By calling Web services, the database can track, aggregate, refresh, and query dynamic data produced on-demand, such as stock prices, currency exchange rates, and weather information.

There is no dependency on Oracle specific database connectivity protocols. Applications can employ any cached WebLogic Server connection.

This approach is very beneficial in heterogeneous, distributed, and non-connected environments. Since database Web services are a part of WebLogic Web services, they can participate in a consistent and uniform development and deployment environment.

Messages exchanged between the Web service exposed database and the Web service client can take advantage of all of the management features provided by WebLogic Web services, such as security, reliability, auditing and logging.

Figure Web Service Calling in to the Database. A request for a type of database service arrives at the application server. The service endpoint implicitly specifies the type of service requested. The servlet passes the request to the classes that correspond to the exposed database operations.

This method simplifies the Web service invocation as the location of the service is already known without needing to look up the service in the UDDI registry. The client proxy class does all of the work to construct the SOAP request, including marshalling and unmarshalling parameters.

The following sections describe the type mappings between SQL and XML for call-ins and call-outs when the Web service is known ahead of time static invocation. The first column lists the SQL types. The literal and encoded values refer to the rules for encoding the body of a SOAP message.
