Before you start:
Before you can define your mappings,
you must have defined already the message or database formats for both the
source and the target that you want to use.
Defining the mapping then involves a number of possible options
and operations:
- Direct assignment of a source field to a target field.
- Assignment based upon some condition, or set of conditions, having
been met.
- Assignment that needs to have a function applied to the source
before it is assigned to the target.
- Assignment that is made after some ESQL is executed, qualifying
the assignment.
- Assignment of a literal value to a target.
The mappings are defined using the Message Brokers Toolkit for WebSphere
Studio.
Note: If a message element is of a type that extends a base type,
only the elements or attributes explicitly defined in the extended type can
be mapped in the Message Flow Mapping editor. To access elements or attributes
defined in the base type, either use the Compute node, or define a type that
contains the content of the base type, instead of deriving the elements or
attributes from the base type.
