Data Driven Systems Modelling* - Tapa blanda

Reseña del editor

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.
