Abstract
Nowadays, information technology is one of the key component of ongoing projects in all sectors. Medicine, mechanical engineering, the banking sector, the agro-industry, all of them are on one level or another side of using information technologies and information systems is to predict, calculate or facilitate automatic actions. Information systems do not only simplify daily tasks, even also makes it possible to use resources optimally. However, the information systems require using of optimal solutions and the choice of implementation technologies by themselves. As a result, it seems relevant to develop an automated system for calculating the most suitable database for projects. The purpose of the research is to develop the system for selecting database, also taking into an account the possibility of using hybrid SQL and NoSQL technologies. This article provides an overview also analysis existing types of databases and a comparative analysis method for choosing a system.
