This master’s thesis focuses on the analysis, design, and implementation of modifications to the DARMA information system within the scope of the ALICE CERN experiment. The objective of the study is to analyze the currently deployed version of the DARMA IS, modify and remove the limitations of the existing solution, and implement modification requirements from the ACC DSC group leadership. Among these requirements are improved integration with multiple archival databases, providing support for alert selection, generation of statistical reports, and detection of improperly configured archiving datapoints. An analysis of the current state of the DARMA information system was conducted as part of the thesis, and areas that could be improved were identified. Based on a requirements analysis, a new concept of a modular architecture based on application libraries was proposed, and the relevant modifications to the information system’s functionality were made. The modified DARMA information system was experimentally verified in the laboratory conditions of CMMRaPI at KKUI using a data copy from the ALICE CERN experiment. The thesis also includes a manual for adding additional archival databases. As part of the system modification, we expanded the web interface with contextual help to improve the user experience. The modified DARMA system is a modern, efficient, and easily expandable information system that allows for better processing and analysis of data from various archival databases used in the ALICE CERN experiment.
