<span>The teaching of relational database design to business students poses many problems. This paper looks at these problems and outlines an integrated approach which addresses the piecemeal and disjointed procedures common in many textbooks. A number of strategies for dealing with other problem areas of the topic are also described from the perspective of the prevailing business environment.</span>

With the extensive use of relational databases in the business environment there is a need to reduce database complexity in order to avoid data inconsistency and redundancy, which can provide a company with unreliable and/or meaningless data and information. The use of the REA Data Model in database design can significantly help with this problem.  The model can eliminate the need for unnecessary data artifacts which should only be generated by the system when needed. This paper also addresses the need for a Relational Database Complexity Metric. A simple and easy to understand metric is presented.

The article proposes a new set of composite indicators-predictors in business tendency surveys, which allow identifying early information signals of a cyclical nature in the economic behavior of business agents. The main criterion for the efficiency of such indicators is their sensitivity to a cyclical pattern and changes in the dynamics of statistical referents. Property such as a statistically significant lead in time series or earlier publication allows them to be combined into indicators of early response. The composite Business Activity Indicator (BAI) in the basic sectors of the Russian economy is calculated by the authors for the first time based on the results of regular (monthly and quarterly) business surveys of Rosstat for 1998–2020 with a large-scale coverage of sampling units. In 2020, the number of survey respondents averaged about 20,000 organizations of all sizes. The index reflects the «common» profile in the dynamics of short-term fluctuations of the key parameters of the economic environment, which consists of the «balances of opinions» of respondents to the questions unified for all sectoral surveys and connected with the reference quantitative statistics with cross-correlation coefficients that are statistically significantly different from zero, with a lead at least one quarter. This is its main difference from the well-known indices of economic sentiment and entrepreneurial confidence. The main components of the BAI are the new composite indices of real demand, current output, real employment, total profits and economic situation. They aggregate the relevant «order» statistics for the basic sectors of the national economy, including the main kinds of industrial activities, retail trade, construction, and services.The article provides a methodological substantiation and an extended procedure for identifying the BAI components; their composition is formed for the entire set of retrospective results of business tendency monitoring in Russia. A new Aggregate Economic Vulnerability Indicator with a counterdirectional profile and varying degrees of symmetry of its dynamics relative to the short-term movement of the BAI is being introduced as the main limitation of business activity. Proactive monitoring of emerging vulnerabilities in the business environment is necessary to warn their large-scale accumulation, prevent the risks of economic downturns and ensure the highest possible macroeconomic stability. This integrated approach makes it possible to determine the novelty of the proposed measurements of short-term cyclical fluctuations in economic development.

The innovative approach reflects the current state of the education system in the country. Subjects of the innovative infrastructure of the educational process ensure the socio-economic development of the economy. The task of expanding the cooperation of the business environment with scientific and educational organizations in order to provide the economy with qualified specialists is being updated. An innovative approach to education involves the processes of improving pedagogical technologies, a set of methods, techniques and means of teaching. The paper uses analytical methods, including content analysis, and offers a comprehensive approach. It allows us to present the methodological support of the issue under consideration in the unity of a practical-integrated approach to the learning process, a project approach within the needs of the business environment and tools of the business incubator for the development of youth innovative entrepreneurship by creating an environment in which students receive additional competencies by directly participating in the development and creation of new products. Project training solves the most important task of integrating science and business, which will give a high-quality result of cooperation in the form of an intellectual product in which the business is interested. An innovative approach in the education system will ensure the competitiveness of educational institutions and the human potential of the economy. It is important for the education system how quickly it changes organizationally and instrumentally, and how it is able to create new institutions. Subjects of the innovative infrastructure of the education system ensure socio-economic development and transformation of the education system. Scientific and methodological support of educational organizations is represented in the unity of socio-economic, psychological and pedagogical components.

Ontologies are spreading more and more in the field of information technologies as a privileged solution allowing the formalization of knowledge. The theoretical model of ontologies is most promising. They are increasingly ubiquitous given the benefits they present. Despite the proliferation of research proposing approaches dedicated to the design of a database from an ontology, the tools to design a database from an ontology are rare or inaccessible. Thus, in this contribution, we present our approach for the development of an Eclipse Plug-in, in order to automatically generate a conceptual model of a relational database from an ontology. To evaluate the usefulness of our approach, we used our resulting Eclipse Plug-in to automatically generate a conceptual model of a relational database from an ontology, customize it, and automatically generate the corresponding SQL script for Data Definition. The results of this experiment showed that our Plug-in constitutes a concretization of our approach and a means of automatic translation from the ontological model to the relational model.
