A proper logical data model is the single most important aspect of database performance, and this text is a complete guide to designing databases to utilize database structures, using examples from the Oracle database. More than the standard rehash of logical database design, Logical Database Design Principles is a complete guide to the logical design of databases for optimal performance. It combines IT theory with pragmatic techniques and covers all aspects of logical database design, including translation of data flow diagrams into data models, formal data normalization and object orientation within a logical data model. Это и многое другое вы найдете в книге Logical Database Design Principles (Foundations of Database Design) (John Garmany)
