Information Modeling the EXPRESS WayOxford University Press, 6 Jan 1994 - 416 halaman Information modeling technology--the open representation of information for database and other computing applications--has grown significantly in recent years as the need for universal systems of information coding has steadily increased. EXPRESS is a particularly successful ISO International Standard language family for object-flavored information modeling. This cogent introduction to EXPRESS provides numerous, detailed examples of the language family's applicability to a diverse range of endeavors, including mechanical engineering, petroleum exploration, stock exchange asset management, and the human genome project. The book also examines the history, practicalities, and implications of information modeling in general, and considers the vagaries of normal language that necessitate precise communication methods. This first-ever guide to information modeling and EXPRESS offers invaluable advice based on years of practical experience. It will be the introduction that students as well as information and data modeling professionals have been waiting for. |
