Mediation flows overview
Mediation modules can be deployed on the IBM® Workflow Server .
In service-oriented architecture (SOA), services represent business functions that can be reused and combined in an ad hoc manner to create responsive business systems. These services have loosely coupled connections, rather than being connected directly to each other.
- Transforming a message from one format to another so that the receiving service can accept the message
- Conditionally routing a message to one or more target services based on the contents of the message
- Augmenting a message by adding data from a data source
Stock Quote example: building a mediation flow
To illustrate a mediation flow, we will use an example of a simple mediation flow that provides stock prices. A client application provides a query containing a stock symbol and customer ID to the mediation flow, which processes the query. The customer's subscription level is determined, and depending on the level of subscription, the query is routed to the appropriate service provider. The quote that is returned from the service provider is converted into the customer's preferred currency before it is returned to the client application.
We are using a mediation flow because we want to use different interfaces from two external service providers, and expose a single interface to the client application. We need to build the service quickly, with the ability to change the application on demand, and without modeling a business process. We also want the ability to change the service provider without disrupting the service.
