The number of contacts between countries and the number of contracts signed between countries are offered as the indicators to determine the integration degree of countries. An approach to the design of the data warehouse for the decision support system in the field of foreign policy, using OLAP-technology is offered. Designed polycubic OLAP-model in which each cube is based on a separate data mart. Given the differences between the data warehouse and data mart. Shown that, one of the cubes of this model gives full information about the chosen indicators, including their aggregation on various parameters. Method for measuring the degree of integration of the countries, based on the calculation of the weight coefficients is proposed. In this regard, was described the information model of the relevant subsystem by using graph theory. Practical application of this method was shown. Moreover, the used software was shown. Index Terms—Integration; integration of countries; indicators of the integration degree of countries; decision support system; data warehouse; data marts; OLAP; OLAP-cube. I. INTRODUCTION The fundamental principle of the international relations of any country includes its interaction with other states. The spheres and directions of international cooperation are diverse. They include economic, political, legal, social, ideological, diplomatic, military, cultural and other fields. Integration between countries, which is nowadays observed ubiquitously, has recently become particularly important among the most obvious manifestations of the basic patterns of international relations. The trend of integration is a higher level of interaction between the states, its deepening, and the development of relations. Integration (from lat. integratio – ―connection‖) – is connectedness of individual differentiated parts and functions of a system or a body forming an organic whole, as well as a process leading to such a state [1]. It is known that the term was first used in the 1930s by the German scientist Carl Schmidt in his ―Theory of large Spaces‖ (―Grossraumtheorie‖) [2]. Nowadays, the term has gained a widespread use in various fields, such as biology, physics, chemistry, policy, and information, social, cultural and others. The article aims at developing a method to measure the integration degree of countries within the framework of the decision support system (DSS) in foreign policy with the use of OLAP-technology. Studies, which include a review of the relevant literature, as well as an analysis of available software, showed that currently, DSSs are being developed and constantly improved in different areas. For example, various approaches to their creation in medicine, healthcare, education, management, marketing, etc., using Business Intelligence technologies, i.e. OLAP and Data Mining, are considered in [3-5]. In [6] designed the urban earthquake disaster reduction information management system, where applied a variety of information techniques, such as GIS and database, and which assisted the decision-making system effectively for the earthquake emergency work. It should be noted that Inter-agency automated information retrieval system ―Entry, exit, and registration‖ has established and currently functioning in Azerbaijan. The system aims at improving the efficiency of relevant public authorities in this area, providing information supply, as well as automating the document flow, allowing inspection, querying, analysis, etc. A distinguished feature of our DSS is its multipurposeness. Thanks to its rich DW it can help solving human resources, financial and other issues, as well as integration issues of the country. In the future, the merger
