 Database design and software product development are two of the most important tasks for IT specialists who are studying databases at higher education institutions. To make these processes easier, AR diagrams are often used, which are based on the concepts of entities and relationships. These diagrams allow students to visually represent a database as a set of connected objects. Cloud services can be used to construct AR diagrams, but selecting the right one can be difficult. In this paper, we identified two cloud services, dbdesigner.net and Lucidchart, that were deemed suitable for teaching database design. We also developed criteria and indicators for evaluating cloud services, which could be used by teachers to select the best service for their needs. This article was authored by Tessiana A.
