IoT devices and platforms are a fast growing market. One can mention a number of businesses relying on easy opportunity to build real-time monitoring systems using modern software and IoT hardware solutions. However, the growth has revealed a number of complex problems. Many problems are in area of data processing and storing huge volumes of information. Due to wide use of different kinds of sensors, and even a sets of sensors within each single device, on one hand, practitioners discover unpleasant effects of data losses caused by data packages losses or delays while its transition from sensor to server. On the other hand, huge volumes of data require to use some big data approaches and many startup projects feel the problem of lack of resources. Many of them feel lack of data storage facilities or become unable to support huge data sets due to lack of finance. The paper is focused to research the problem approximation for incoming data stream to make it smaller the volume of data to be stored but to keep it possible to be used. A few approaches to use such data compression via its approximation are discussed with application to IoT based real-time monitoring system.

The research objective of the article is substantiation of methodological and applied recommendations for improving the system of financing the sustainable development projects in Ukraine in view of Sustainable Development Strategy realization. The study object is financing the family firms in framework of reforming the Ukrainian legislation aimed at establishing of a mechanism of funding the sustainable development projects. During the research there were used such methods as: dialectical method and methods of analysis and synthesis -to study the features of forming the national programs of the state development, the characteristics of private-public cooperation in the implementation of sustainable development projects; statistical method -to analyze the family firms' expenditures by their content and direction, for empirical determining the costs, which can be potentially directed on sustainable development measures of Lviv region; structural and logical analysis -to develop theoretical and methodological principles of forming an effective Program of the regional competition of sustainable development projects for family firms in Ukraine. The need to increase incomes of Lviv region family firms was established. This will facilitate the development of small and medium businesses in the country. There were characterized supporting programs and projects for sustainable development for the purpose to encourage households to make the appropriate changes, providing assistance through common financing.
