Book Description Paperback. Condition: Good. Conceptual models emphasize the essence of information systems. They are concerned with meaning, that is, semantic relationships between real work objects. Implementation models deal with data structures and programs, and are concerned with efficient use of data processing resources. This book introduces the theory and practice of conceptual modelling, and demonstrates its use for system design and implementation. It ties information engineering with the more traditional structured analysis approach and with the relational model, as implemented in state-of-the-art database environments. This book is designed as a primer and a reference manual for the student and the information systems professional. The book has been read but remains in clean condition. All pages are intact and the cover is intact. Some minor wear to the spine. Seller Inventory # GOR012395555
