Another kind of classes generated are Entities which are Object representation of Table.
Each database Table or View has own Entity created.
All classes are generated into table or view package, which s located into package related to particular scheme of the database.
Entity may be located into scheme folder, however the location of the object is not important. You can move it wherever you want. Also you can use the same entity to call different DataBaseTarget, if it has the same table created.
