Інформаційна взаємодія у розрізнених інформаційних системах ситуаційних центрів

Abstract

The article is devoted to the problem of information exchange between automated systems of situational centers (SC) of the government authorities of the Security and Defence Sector (SDS) of Ukraine. The prob-lem is extremely topical today, since in the event of nationwide threats (military intervention, terrorism, emergencies), the SDS should work as a single well-coordinated mechanism. Therefore, the creation of the SC SDS system and the establishment of information exchange between them is a prerequisite for this. The paper assesses the most common types of data integration in information systems (IS), such as data ware-houses, data federation and service-oriented approach. As the most modern approach to information inter-action of disparate ISs, a service-oriented approach is proposed. It is noted that for data exchange it is inappropriate to get access to “other” IS and independently search for the necessary information there. Alternatively, it is proposed to isolate the data exchange subject area (SbA) from the IS subject areas of various SCs and to determine the topics necessary for the exchange. Next, for each topic, to build a the-matic view of grouped, analytical data by the type of data mart. Such views will become a data source for the corresponding services in SOA and can be used in Publish/Subscribe and Request/Response modes. The paper considers a method and proposes an algorithm for the interaction of ISs of disparate SCs based on the use of the ontology of SbA data exchange and SOA. The MIP4-IES family of data exchange specifi-cations of the NATO Multilateral Interoperability Program (MIP) is taken as an example. On the basis of legislative documents in the field of emergency response, an ontology of data exchange between the IS of the SC in response to emergency situations has been built. Examples of topics and thematic views are given that can be constructed on the basis of the constructed SbA ontology for data exchange.
