Making data base work is the goal of this new book. It will guide you toward an in-depth understanding of the data base environment-its components, their interaction, and the results they achieve. Your success in using and controlling the data base environment depends on an understanding of data base syntax plus the underlying activities at the system level.
Among its special features, the book:
· addresses the operational and decision support data base environments from three levels-physical, system, and user
· guides you through basic data management concepts such as indexing, randomization, variable length data, variable field data, and physical blocking
· examines the design practices for online performance and availability
· reviews the syntax, the physical implementation, the usage, and the economics of IMS, Model 204, SQL, FOCUS, and dBASE II
· contains a tutorial in some of the data base management systems directing you through the creation, update, access, and other usage of the data base systems
· includes inserts on such topics as content addressable memory, non-vendor-supplied utilities, design review, "deadly embraces," and others
· discusses distributed processing, data base machines, teleprocessing dynamics in a state of the art fashion
