There are a number of significant papers which develop the themes that are essential
to development of an 'open world assumption' dbms.
The first of these of course is Codd's important 1979 paper (often referred to as his 'RM/T' paper)
in which he explicitly
recognises the importance of using both closed-world and open-world relations.
The full text of this paper is available online (in PDF format) at
Development of the OWA ideas can be traced through a series of unpublished and
published papers by Stephen Henley and others:-
Some of the original G-EXEC papers from the 1970s have been scanned and these may be downloaded in PDF format.
(Papers published in Computers & Geosciences reprinted with permission from
copyright 1976, 1977, 1978)
- 1976: Design Philosophy of the G-EXEC system (K.G. Jeffery & E.M. Gill)
- 1976: The Geological Computer (K.G. Jeffery & E.M. Gill)
- 1977: Communication of geological information aong different soft machines (S. Henley, K.G. Jeffery, C.J. Fage, and E.M. Gill)
- 1978: G-PLOT: Graphics in the geological computer (S. Henley, C.J. Fage, K.G. Jeffery, and E.M. Gill)
- 1978: A systematic approach to modelling of multidimensional geoscience data (Bell, A.M, Duncan, S.V., Fage, C.J., Gill, E.M., Henley, S., Jeffery, K.G., & Read, M.G.C.)
- 1978: The use of G-EXEC for resource analysis (K.G. Jeffery & E.M. Gill)
- 1980: G-EXEC system capabilities (unpublished summary of the system)
Finally, some of the papers showing the development of DATAMINE clearly
illustrate the direct derivation of DATAMINE design principles, and indeed much
of its coding, from the G-EXEC system.
These papers will be scanned and uploaded in due course.
