| Abstract [eng] |
The object of this study is the use of context in decision support systems. With the use of the method proposed for modeling, models may be integrated into information systems with the help of contextual graph. This method is suitable when the use of other methods of integration is either impossible or not cost-efficient. The method allows to create, edit and install decision patterns centrally. Moreover, a potential to change and manage the rules is intended not only for programmers, but also for business people. This allows to reduce costs of creation, editing and administration of decision support systems. Also, this method ensures a better system agility. This study consists of three parts: introduction, analysis, method description and experiment. The introduction substantiates the topicality of the problem, formulates the main objective and tasks of the research, describes the scientific novelty of the study, presents the reports by the author, and the structure of the paper. The first chapter presents the analysis of use and meaning of context in information systems. A comparative analysis of context modeling techniques is presented, followed by the general conclusions on the analysis. The second chapter describes the method for integration of context in information systems. Contextual graphs is selected for modeling decisions allowing realization of the proposed method. Business rules are analyzed together with possibilities to transform contextual graphs into them. The chapter provides the description of requirements, design ant the realization of the system being created. |
