that can't be constructed directly by the client for whatever reason. A
special case of a factory is a singleton class, like Java's System and
Runtime classes, where you call a static method in order to get a reference
to the actual object.
A manager is (in my view) a class that provides a cohesive interface to one
or more objects that do related tasks. It might provide methods for
creating business objects, updateing and deleting them, as well as various
methods for recalling recordsets that back those BOs. It'll probably have
methods like createDocument, getDocumentById, updateDocument,
deleteDocument, getDocumentList, getPostedDocumentList,
getUnpostedDocumentList, getRecentDocumentList, etc.
