What is Designer?
Designer is a BusinessObjects IS module used by universe designers to create and maintain universes. Universes are the semantic layer that isolates end users from the technical issues of the database structure. Universe designers can distribute universes to end users by moving them as files through the file system, or by exporting them to the repository.
