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.
The methodology of database construction on methods of local technogenic pollution elimination in rock massifs is considered. The characteristic of optimal conditions of database application is given, rational type of its data organization is justified. The system of relational relations between the database objects is built on the basis of the information-logical model of the subject area.
