The Evolving Data Dictionary
Abstract
System Analysts have used a variety of techniques to define, implement, and document information systems. As databases grew large, it became increasingly difficult, if not impossible, to determine what data elements were used by what applications. In many cases, as needs changed, it was easier to build a new application with unique data elements than it was to try and find existing data elements that could be used. Data dictionaries were built to solve this problem. Originally hardcopy references, data dictionaries are evolving into fully automated, in-line active control mechanisms. Data dictionary functionality continues to evolve in the direction of heterogeneous sy system access support and information management.
