Offers intelligent method of assessing the reliability of data (verification), in databases, based on the theory of artificial neural networks. The method consists of three steps: data clustering using the Kohonen network, training radial basic network and its computation using the validation database table rows. To create a radial basis networks and their training Backpropagation developed software tool. The proposed verification method of data can be used in various applications of information systems.
Keywords: database, relational algebra, verification, radial basis neural network training neural networks, Kohonen networks, clustering.

In this paper, a comparative analysis of the shift parameter distribution initial set of calculated analytical method and simulated, obtained by computer simulation using sample data. Error δi shifts between the parameters listed in the table and plotted errors on the scope and volume of the aggregate.
Thus, increasing the volume of the aggregate error is reduced from 30% to 1% at a constant volume sample m = 50.
Keywords: sampling, aggregate, volume, range, accuracy, distribution, performance analysis, engineering, reliability.
