Query as a Web Service (QaaWS)

The Query as a Web Service (QaaWS) connection method enables the Xcelsius visualization. QaaWS provides real-time CA Clarity PPM data through the web services provided by Business Objects.

The Query as a Web Service connection method is a good choice when:

• You want to get the real-time CA Clarity PPM data through your Business Objects web services.
• You prefer to use CA Clarity PPM Business Object universes to establish the data source. Experience writing NSQL is not required.

Important! To use this connection method, you must have access to the Business Objects Query as a Web Service tool. If you are licensed to use CA Clarity PPM through a service provider, contact your service provider to discuss your connection method options.

Secured data transfers are established in the following ways:

• Authorization. A secured session is established for the logged in CA Clarity PPM user by making the Business Objects Session ID available to the Xcelsius visualization. To establish the session, a flash variable, CELogonToken, is created in the Xcelsius visualization and mapped to any cell in an Excel sheet. The interactive portlet uses the Business Objects Session ID global parameter.
• Access control. User access rights are preserved through Business Objects universes. The stock CA Clarity PPM Business Objects universes are configured so that users see data based on access rights.
