Message types

The following message types are used in the examples:

• Map Example FlatStructureMessage The structure of this message type is kept simple. Message instances of this message type consist of none or multiple records of the Person element.

  Since one person can have multiple telepehone numbers, it is possible when using this structure that there are multiple records in the message for one person where the ID and name are identical but where the telephone numbers are different.

• Map Example NestedTablesMessage The structure of this message type explicitly takes into consideration that one person can have more than one telephone number:

  The TelephoneNumber element can occur more than one within a Person record so that it is not necessary to have multiple Person records for the same person in order to be able to transfer multiple telephone numbers for this person.

• Map Example TwoTablesMessage The structure of this message type organizes information for people and their telephone numbers in two separate structures:

  The telephone numbers can be assigned using the PersonID element of a person with the same ID .

The examples assume the following prerequisites:

• One person is identified uniquely by one ID. Depending on the message type, the value of this ID is either in the ID or PersonID field.

• There is exactly one name for each ID. Names never occur more than once.

• A person can have multiple telephone numbers.

Overview

The message mapping Map Example FilderRecordsByQualifier uses the same message type Map Example FlatStructureMessage as the source and target message type. For all other message mappings, you can tell from the technical name of the message mapping what message type the outbound message types and target message types are.
