Database Design Theory (Macmillan Computer Science S.) - Tapa blanda

Sinopsis

The chief aim of this book is to establish a theoretical basis of database design, focusing in particular on the relational database as model. The book is divided into four parts. The chapters of Part 1 introduce the concepts required for the modelling of data. Part 2 examines the problems encountered when embarking on a design and puts forward some solutions for transforming the relational model of an application into an internal data structure. Part 3 tackles more complex problems, such as data redundancy, integrity rules and cyclic data structures. Here, the solutions put forward lead to operational results that are founded on known mechanisms, such as the decomposition of a relation, but also on new mechanisms which are described in part 4.
