Abstract
The paper discusses issues related to the creation of a database of materials for industrial and medicine applications. This database is developed to accumulate information about the mechanical and other properties of materials under study and the corresponding sources of information. The paper mainly focused on organizing the change log of the described database. The change log allows one to store, display and analyse all changes made in the database. The technical solutions are presented allowing to implement universal models for logging changes that are invariant with respect to the composition and structure of the tables used.
