A relational rock mechanics database scheme with a hierarchical structure

In this work a hierarchical rock mechanics database scheme is presented. The aim of this database is to store and represent rock mechanics test data in a standardized and “transparent” manner (format) that includes as much information as possible regarding rocks, sampling location and orientation, testing procedures, experimental results, data reduction and model calibration methods. For brevity, in the first presentation of the database only the first two hierarchical levels of analysis are presented. Initially, the database structure is described and subsequently, the relations between different components of the database are illustrated. A short description of each parameter stored for each type of test is also given. Finally, a Web application scheme for the management of the database is proposed.
