Theres a little bit of redundancy; a few concepts are introduced more than once. Unlike a logical design, a physical database design is optimized for data-access paths, performance requirements and other constraints of the target environment, i.e. Database Design is a collection of processes that facilitate the designing, development, implementation and maintenance of enterprise data management systems. Physical design is the process of choosing specific structures and access paths for database files to achieve good performance for the various database applications.

Database design starts with a conceptual data model and produces a specification of a logical schema; this will determine the specific type of database system (network, relational, object-oriented) that is required. read more. x][su*$H`&]*VIP Y-I I3 ET@9DdJRRX%,;I~ s iIPBavzzzf>=W\qW\qW\qW\Y{Q4CQ3iL:"o}wo`.?
