Native web services is a new feature of the XML DB technology. In google i found that it`s very close to SOA.
Can anyone simply explain: 1) what is the main usage of Native web services 2) what is the main difference of XML DB 11g and previous XML DB releases.
Thanks.
It allows you to publish your PL/SQL packages/procedures/functions as a web service with zero coding and zero deployment effort!
I found documentation. It was hard )
New features:
And about web services.
Web services provide a standard way for applications to exchange information over the Internet and access services that implement business logic. Your applications can access Oracle Database using native Oracle XML DB Web services. One available service lets you issue SQL and XQuery queries and receive results as XML data. Another service provides access to all PL/SQL stored functions and procedures. You can customize the input and output document formats when you use the latter service; the WSDL is automatically generated by the native database Web services engine.
SOAP 1.1 is the version supported by Oracle XML DB. Applications use the HTTP POST method to submit SOAP requests to native Oracle XML DB Web services. You can configure the locations of all native Oracle XML DB Web services and WSDL documents using the Oracle XML DB configuration file, xdbconfig.xml. You can also configure security settings for the Web services using the same configuration file.
There are advantages and disadvantages. If you have developers experienced in PL/SQL, this makes it easier for them to provide and consume web services without going through a separate app server.
Of course, your security people may get involved there, especially if you want to make those services available outside your Intranet. But it provides one more tool in the toolbox.
I wrote a paper introducing PL/SQL web services for last year's ODTUG conference. It's available in the Tech Resources section at www.odtug.com. Take a look.
