Abstract

In the article such ways of optimization of the structure of a database of complex structured objects that allow simplifying the scheme of an information system. As a result, the response time of the information system to the user's request is reduced, and it becomes possible to more effectively manage and monitor the progress of ongoing processes. A formalized model of the relational expression is developed, a model of the corresponding equivalent transformation of the chosen relational expression is created, a formal description of the developed algorithm for optimizing the queries is presented.
