This work is devoted to the design and development of an intelligent information system for predicting the phase stability of solid solutions. Such solutions are used as a base for new luminescent materials. The main trends in the development of intelligent information systems were analyzed that led to a modification of a model for predicting the phase stability of solid solutions. The paper presents a variant review and selection of software design and development methods. Oracle Application Express (programming languages javascript, HTML, pl/SQL) and pl/SQL developer (programming language pl/SQL) were chosen as the software design environment. The paper also contains the analysis of database design methods with the software developed, including a definition of the main functions of the system.
