#4 Basic Code Generation: User Defined Datatype Mapping

[Larry Rix]

Design, build and test a User Defined datatype mapping where the user can override the default mapping used to generate Eiffel class code from a database source.

Primary Use Case:

1. User selects generic db-to-class mapping --> db-to-class mapping stored as a generic or default XML declarative specification document.

Alternate Use Case:

1. User selects specialized db-to-class mapping based on a specific database --> specialized db-to-class mapping is stored to a named declarative XML specification document.

NOTES:

1. The user must be able to add, save, open, change and delete specialized XML specifications, but not the default or generic.
2. Generate appropriate tests both model and GUI.
