Логическое проектирование информационного обеспечения распределенных информационных систем критического применения

Abstract

The article deals with new information technologies for building a data warehouse in a distributed information system of critical application. The existing principles of creating data warehouses, as well as the outlined ways to improve them, are always associated with the collection, storage and use of information that is recorded at a certain point in time, while they store data corresponding to the last time count. This approach to the development and application of data warehouses can be called static, since it does not store or display the behavior of objects at past points in time. However, the objects that are included in the data warehouse have pronounced dynamic properties and therefore must be displayed dynamically. The way out of this situation is the creation of analytical data warehouses, which will provide an opportunity to more effectively solve traditional and qualitatively new tasks in the system under consideration.
