Information-analytical systems (IAS) are essential for conducting scientific research in the digital era. They enable researchers to access, analyze, and process information, collaborate and share knowledge, optimize information retrieval and update, and support decision-making processes. In this paper, we examine the concept of “IAS for supporting scientific activities” and present some examples of IAS developed by Ukrainian scientists for various research domains. These IAS help researchers store, organize, and analyze information on the scientific research outcomes in Ukraine, which improves the efficiency and effectiveness of scientific activities. We also discuss the benefits of using IAS for scientific research, such as accelerating the pace of scientific discoveries, providing wide access to scientific information, facilitating knowledge exchange, and contributing to collaborative solutions for complex problems.
