description: The tasks that were solved during the research: 1. To analyze the existing solutions. 2. Develop the architecture of the solution. 3. Realize the product according to the requirements. 4. Conduct comprehensive testing. 5. Evaluate how suitable the new API is for creating production-ready products. During the development process, we conducted a detailed study and comparative analysis of existing technologies, which allowed us to determine the most suitable option for the implementation of our system. As a result of the study, we decided to use Cassandra DBMS as the basis for our architecture. This decision was due to a number of advantages of Cassandra, such as high performance, scalability and fault tolerance. Based on the analysis, the system architecture was designed taking into account possible changes and the necessary logic was implemented. Then the code was written, and unit tests were conducted to verify the system performance. The new API developed for interaction with the system was also evaluated. The result of our work was the successful implementation of a database management system using Java 21 API. This system ensures efficient data management and provides users with convenient and reliable access to information.
