Relational Database (Tutorial guides in computing & information systems) - Tapa blanda

Sinopsis

The relational database has become the dominant model for the storage and retrieval of record-oriented data in commerce, industry, science, education, government and many other areas. As the use of these systems grows, more and more emphasis is placed upon their sound design and efficient use. This book provides a comprehensive coverage of all design and implementation issues concerning relational databases. Assuming no previous knowledge of the subject, it begins with a discussion of the database approach, together with its advantages and architecture. The life cycle of a typical system is explained and entity-relationship modelling is covered thoroughly. There is comprehensive treatment of relational representation and normalization as well as an in-depth exposition on the query language SQL, illustrated by many clear and well documented examples. The important issue of database administration is included and the book concludes with a chapter on the essential matters of database recovery and concurrency. The material is intended for all undergraduate and Higher National courses in any computing and information systems programme and the book is also particularly appropriate for practitioners who wish to acquire a comprehensive and practical understanding of the subject.
