Abstract
This paper presents a new model for a scientific data bank applicable to geological data. It is composed of four concentric rings, described from outside to inside as: 1. (1) an optional conversational module for graphic display, 2. (2) a data structure (indicated as DS), 3. (3) an interface data structure/storage structure, and 4. (4) a storage structure which is a file system. The users do not need to know the nature of 3 and 4. In this paper, I emphasize the DS and the principles to build it correctly; it must never be created to answer to a particular problem; it only depends on the analysis of the nature of geological phenomena and of the relations among them. The DS is composed of four abstract data types and consists of an arborescence with links. The programming language of the entire system is SIMULA 67, which is ideal for data structuring and for geological progressing. The result is a powerful DS which may resolve almost all problems. Two applications in geology are presented. The first example concerns geological, mining, and topographical cartography. The graphic elements are considered as belonging to oriented multigraphs, according to a method based on graph theory and used originally to digitize maps. Among the problems which may be resolved are selective two- and three-dimensional drawings with isolines and boundaries, estimates of dips, surfaces and volumes, correlations, etc. This system establishes a base for geological simulation and modeling. The second example, discussed briefly relates to the collections of paleontology of Université P. et M. Curie. This project is in progress and shows potential for a wide application in the natural sciences. As part of the overall objective, the concept of the data bank developed is intended to allow for scientific and industrial applications, in which display and simulation of natural and physical processes may be necessary. At present, many aspects of this research are experimental.
