Example text

These are two examples of intermediary sites. They are intermediaries in the sense that your customer invokes the intermediary’s application on the intermediary’s channel running on its servers, not your application on your channels. These intermediaries provide a value-added service that you alone cannot provide. They facilitate efficiency and decision-making processes needed by the user to make a more effective decision. They can expedite the process, thereby reducing the users’ work effort and time commitment.

For "Role" equal to "Account" Deny Access to All Records where "IndexedID " Is not equal to "AccountID ". For "Role" equal to "Account" Allow Access to "Account Correspondence Records" where "IndexedID" Is equal to "AccountID ". and deploying links to the same Web service, both members and accounts will be able to view their correspondence through the Web channel as well. Yes, we invested some additional time and money to build services around a paper channel, but that initial investment was leveraged with minimal effort (development of a second service stub) to a second channel (the Web) and reused by three constituents (members, providers, and accounts).

Most of the intermediaries now allow for the pass-through of the appropriate information to allow back-end partner services to handle these conditions. Regardless of who performs the user authentication and service authorization, the key aspect of the channel layer in the SOA framework is that it is the layer where authentication is performed and where service privileges are determined. I use the term service privileges for explicit reasons to distinguish this process from the transaction or information authorization associated with a service.
