InDesign was positioned as a high-end alternative and successor to Adobe’s own PageMaker. InDesign’s primary adopters are designers of periodical publications, posters, and other print media; longer documents still are designed with FrameMaker (manuals and technical documents) or with QuarkXPress (books, catalogs). The combination of a relational database, InDesign and Adobe InCopy word processor, which uses the same formatting engine as InDesign, is the heart of dozens of publishing systems for newspapers, magazines, and other publishing environments.
