data aggregation

In this paper, a methodology for benchmarking study of the market infrastructure development in regions of Ukraine is developed. As indicators for comparison, the number of active enterprises in the sectors that make up the market infrastructure was chosen. The suitability of standardization of output data by the standard deviation of the mean (Z-index) is grounded. The aggregation of standardized data is carried out by a simple arithmetic mean. The aggregated data are evaluated by two methods: ranking and grouping with irregular intervals.

This paper is devoted to the principles of constructing a software system of the aggregated data formation. The main principles of constructing a software system of the aggregated data formation are considered and their comparative analysis are carried out. An alternative principle of constructing a software system is proposed. This principle of constructing allows to eliminate the problems of fast and reliable data processing, scaling, automation of the software system components, improve data quality and security.
