The article is devoted to the description of the method of multidimensional database,which is an effective method of data storage, which allows analyzing data qualitatively, andmost importantly in a short time. The article discusses the capabilities of multidimensionaldatabases, in particular, multidimensional OLAP (On-Line Analytical Processing) cubes whenanalyzing large amounts of data. Provides an overview and features of a multidimensionaldatabase and discusses the steps you need to take with a multidimensional database tounderstand the structure and capabilities of an OLAP cube. To create a knowledge base, itdescribes the steps you can take to create and execute a multidimensional database thatyou can collect from various sources, save to a database, and then prepare a report usingOLAP analysis. Various information system data processing technologies such as OLTP andOLAP were considered. The algorithm of the data storage process for analysis purposes wasstudied. A model of a multidimensional database in the form of a three-dimensional cubewas presented. Examples of analysis and ways of obtaining information from the data cubewere also given. The use of a multidimensional database in higher education institutions as asimple and effective method of data storage is considered. There are also illustrations of thestructure of a higher educational institution to see the bulkiness of information, and what kindof information database operates in the educational institution.
