This article discusses methods for designing distributed information systems for use in design using the Hyperledger blockchain platform. Of course, the main stages do not differ, but there are also differences that will be identified in the course of the study and a proprietary approach to the implementation of these features is proposed. The request for the possibility of decentralizing business processes in certain areas (such as financial transactions) led to the emergence of distributed ledger technologies, w...

There is a problem of a traffic block nowadays, which started in the middle of the last century and had become a real disaster for many developed countries. There is a variety of methods of traffic regulation and traffic flows management, which were developed at different times. One have become irreparably out of date and does not provide the solution of the traffic block problem in present conditions of growth of vehicles amount. Another allow to improve the management of urban traffic flows, but a lot of resourc...

Structure-independent databases are widely used in different spheres for specific tasks solving. Nevertheless, their main problem is a low efficiency that prevents them to be in progress. This work is concerned to the problems associated with data insertion. The causes of this low performance can be called the use of the existing object method of procedures creation and heterogeneity of the data insertion procedures creation process. This process uses object representation form for process of data insertion proced...

Currently, the design and development of the user interface is important, but at the same time, an empirical process. Despite the attempts of many authors to give recommendations on the correct design of the interface appearance, there are no recommendations on how to relate the domain and interface, and build the latter without losing the sense of the user's activity. Unlike the existing approaches in this area, the proposed approach to the semantic design takes into account the activity of the user in the domain...

Specific models and storage technologies which is possible to save domain semantics are required to create configurable information systems. This is why modern researchers talk about the high cost of domain models in comparison with a program code. But they don't suggest any approaches for including this model as a component of the system itself. Existing approaches for domain modeling during the transition to final stages of a system life cycle tend to lose the semantic component of the data. They only allow to p...
