The Structural Stability of Corporate and Devolved Databases

J. Carden *

Database Management Systems are observed to operate in distinct environments within organisations. These environments are classified as ‘Corporate’ and ‘Devolved’, and different types of database management systems are considered as more appropriate to each. The corporate database is closely associated with an evolutionary model of the entire organisation, whereas each devolved database is a tool used by an individual or group to analyse information necessary to that person's function within the organisation.

The requirements for a Restructuring Mechanism to allow a corporate database to be altered in structure to reflect alterations in the organisation and enchancements to the model are identified.

Conclusions are drawn that a Restructuring Mechanism is an essential ingredient for a Database Management System, to allow the database to reflect the ever-changing structure of an organisational data model. Areas where future research is likely to be fruitful are identified, and it is suggested that the classification of corporate and devolved will be useful in this respect.

Received September 1984.
