Designing and Implementation of the Information System for Providing Recommendations to People With Mental Disorders

The authors of the article have developed methodological grounds, designed and implemented an information system to provide recommendations to people with mental disorders. The analysis of the main ways of using information technology in mental health treatment has resulted in the finding that mobile devices with certain software can significantly reduce the number of visits to qualified specialists, which make mental health therapy much more accessible to people with limited time or material resources. The authors have designed the information system using a structural approach and design model Data Flow Diagrams (DFD). They have also developed a context diagram of the information system and decomposed its main process to demonstrate ways to convert input into output. The authors have described the features of the decision-making method — the decision tree used in the information system. The functional purpose and the algorithm of work have been presented in the form of a Petri net, also the authors have specified on the tables of positions and transitions of this network for a better understanding of system principles. The analysis of software tools has been done that allows us to achieve the set goals in designing the system. Verification of work has been carried out which is proved in screenshots of program windows of the system and contents of the main pages has also been described.
