Configuring Hello World for the database

The WireHose frameworks are database independent; a WireHose application can use any database which is compatible with WebObjects. There are two primary techniques which are used to achieve this: replacing the adaptor dictionary, and the use of attribute prototypes.

Note: For maximum performance, WireHose fetchers use custom SQL, some of which may be incompatible with some databases. Use of this SQL can be controlled by several system properties. In general, any database which supports subselects should work properly with WireHose, though databases that support SQL set operators such as INTERSECT and EXCEPT (or MINUS) will perform better.
