♦ CORBA Server - The CORBA Transformation Server executes a single map each time that it is
called. Like the Tuxedo Server, it can exercise maps that use external adapters for output, as well as
maps that return the output in the response. (Refer to the diagrams for the Tuxedo Server.) No
CORBA adapter is provided, however; so if transformed data must be sent on to another CORBA
server, the client must forward the data itself.

Developing Application Interfaces
To design an application interface, you need to understand the content of data, as well as the range of
data sources and targets you want to use to transport that data. You also need to define rules for
transforming data content from inputs to outputs.
As you begin to develop more interfaces, you will want to re-use metadata and transformation rules and
formulate workflow models (interface systems consisting of transformation components that are
configured to work together). These systems also need to be re-usable.
Mercator’s Design Studio, an integral part of each Mercator product, is used for all of these
development activities.
Modeling the Data of Business Objects
Even though you can use Mercator’s Design Studio to represent properties of individual fields,
