Relational Data Dictionary Compatible with the National Bureau of Standards Information Resource Dictionary System

摘要

Data is a very valuable corporate asset. How it is managed and controlled can often determine the success or failure of a corporate venture. With this fact in mind many organizations are taking a close look at what tools are available to help them in this effort. This thesis takes a look at two types of data management tools available today, the Relational Data Base Base Management System (DBMS) and the Data Dictionary (DD). It discusses desirable DBMS and DD characteristics with particular attention being paid to the shortcomings of DDs. It also describes the effort of the National Bureau of Standards (NBS) to develop a DD standard and examines in detail the NBS Information Resource Dictionary System (IRDS) and how the standard was implemented in a prototype IRDS.
