Effective systems of technical diagnostics, performance information exchanges largely determines the optimal construction of their constituent structures of local databases. This paper proposes a formal approach, which allows you to design effective database structure for use in technical diagnostics. Proposed article approach is based on solving the problem of normalization of the logical structure of the graph, each node of a computer system; determination disconnected and weakly connected components (subgraphs) of the graph of the logical structure of each node, the design of local databases, supported by specific database management system. The simulation showed that the overall query processing time for the proposed structure of the database has decreased on average by 15 % compared with the traditional approach to their design.
