Analysis of the structure of the subsystem of data collection in the system of support of holding sport competitions (by the example of tennis)

The paper considers the introduction of information technologies into the field of sports events (for example, tennis). The system classification of the factors, which can influence the course of the game, is made; the technological process of IT-technologies for holding tennis competitions is presented. The paper identifies three functions of management: collection and processing the data, data quality assurance and control of the requirements to protection and reliability. For performance of the first function, the diagram, including 43 indicators of the average level, is built. For the other two functions, the methods based on the models of initial data are described. The general scheme of the implementation of the subsystem of the original data is constructed.
