Title

¬A new framework for dynamically evolving database environments

Abstract

Describes research work which investigated dynamically evolving database environments and corresponding schemata, with the aim of allowing storage and manipulation of variable length data, a variable number of fields per record, variable length records, manipulation of authority records and links between records and fields and dynamically defined objects (relations in the traditional sense). Proposes a new framework for the definition of a unified schema that eliminates completely the need for reorganization at both logical anad internal levels, and in which retrieval of data is optimized through self contained storage chunks that also vary dynamically
