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...

The purpose of the paper is to implement a method which can synthesize effective data insertion procedures for structure-independent databases based on the Tentzer model. This is a universal database model, which is based on static reference relational tables, linked in a certain way at the physical data level and the logical structure is a meta structure over it. This method makes it possible to synthesize data insertion procedures for such databases, and as result two types of inhomogeneities will be eliminated ...
