Object-oriented information systems analysis: a framework for object identification

Proposes a framework for an object-oriented information systems analysis based on a general model for levels of abstraction in an information system. The framework distinguishes four major categories of objects: user objects, corresponding to the users of the information system to be developed; objects of the Universe of Discourse (UoD) about which the system is to communicate information to its users; information type objects, corresponding to the queries, documents and reports defining the detailed information content of the system; and user interface objects such as windows, menus, icons, etc. mediating between the information system and its users. The framework is illustrated using a case of an inventory control system.<>
