The purpose of this paper is to model the processes of an information system for analyzing and checking the composition of products, as well as to evaluate the quality of this information system. A detailed description of the database structure of the information system for checking the composition of products, the requirements for its development and the relationship between its tables are also the tasks of this paper. The work includes modeling of the processes of the information system for analyzing and checking the composition of products. In particular, the interaction between the actors and entities of the information system is represented by a use case diagram. The main actors of the information system are identified as Anonymous User, Registered User and Administrator. The structure of interaction for the information system for analyzing and checking the composition of products is presented in the form of a relevant interaction diagram. The graphical representation of the set of actions of an information system is depicted using an activity diagram. Representation of information system’s components, dependencies, and relationships between them is presented using a component diagram. The paper proposes to display computing nodes, components, and objects executed on these nodes using a deployment diagram. The paper also contains a selection of quality indicators for an information system for analyzing and checking the composition of products that satisfy the characteristics/sub-characteristics of software quality according to the ISO/IEC-25010 standard. The analysis of metrics that satisfy the characteristics/sub-characteristics of software quality according to the ISO/IEC-25010 standard shows that the following characteristics are suitable for evaluating the quality of an information system for analyzing and checking the composition of products: Functional suitability and its sub-characteristics Functional adequacy, Data exchangeability (Data format based), Data exchangeability, (User's success attempt based), as well as the characteristic Efficiency and its sub-characteristic Throughput. Methodology of the study is based on CASE-technologies for modeling the processes of an information system for analyzing and checking the composition of products, technologies and principles of database development. The study is also based on the selection of methods for evaluating the quality of an information system for analyzing and checking the product using ISO/IEC-25010 metrics that take into account the specifics of using this information system. Results of the quality indicators’ monitoring of the information system for analyzing and checking the composition of products, which was carried out according to the defined indicators, showed that the information system is of appropriate quality according to the ISO/IEC-25010 standard, but identifies possible ways to improve it. Practical implications. The proposed model of an information system for analyzing and checking the composition of products and the structure of its database are the basis for developing the architecture of the relevant information system. The quality indicators defined in the work according to the ISO/IEC-25010 standard make it possible to establish appropriate quality criteria for similar information systems. Value/originality of an information system for analyzing and checking products is its versatility, in particular, its application not only in the food sector, but also in the cosmetic, medical and other industries.
