Abstract

The methodology and structure of the database (DB) on methods of elimination of local man-made pollution in rock massifs has been developed. At the stage of DB information model development, the relational data model with the use of the mathematical concept of the theoretical-multiple relation was applied. The choice of a way of the organization of a DB is defined as a result of the analysis of character of the placed information taking into account requirement about maintenance of direct access to it. The database is a set of normalized tables containing modules of information. Compared with databases, the construction of which is based on other principles, normalization provided more efficient operations with the database: adding, modifying and deleting data. Table normalization also allowed reducing the physical volume of the database (the size of its record on the medium) and increasing its performance.
