The article analyzes modern approaches to the use of data warehouses and data lakes in the construction of information technology platforms for smart regions. Data processing technologies in data warehouses and data lakes allow for the integration, storage, and analysis of large amounts of information generated by various sources, including operational transaction systems, IoT sensors, and other data received in real time. The effective use of data warehouses opens up opportunities to improve the quality of regional management, optimize the work of all services, and raise the standard of living of the population.
The creation of information and technology platforms for smart regions using data warehouses and data lakes is a key direction in the development of modern information technologies, allowing them to be used effectively not only in densely populated cities, but also in areas with complex geography, multinational structures, and diverse economic sectors, such as Transcarpathia. The article discusses the features of building data warehouses and data lakes as components of an information system-from the level of operational processing to the creation of data showcases that provide localized access to information for specific areas of implementation, in particular for the State Emergency Service of Transcarpathia.
