The data warehouse in the information system is intended to reflect the changing part of
the domain model. In classical information systems, this part includes data values, and the storage, implemented as a database, and the system itself can be considered static in time objects. Modern conditions for the functioning of information systems are characterized by the requirement for the possibility of modifying the functionality of the system at the stage of its operation. In this regard, not only data values, but also the domain model, which is reflected in the information system, become a changing part of the system. A class of information systems has the ability to change the domain model, in various sources called configurable, adaptable, evolutionary, etc. Systems of this kind put forward new requirements for storage tools, which include changing the data domain model without redesigning and re-developing, maintaining the connection between system components and data elements regardless of changes made. To date, various methods and approaches are known that successfully solve the problem of changing the stored data model; these include structurally independent databases, situationally-oriented databases, universal databases, etc. The main idea of ??such approaches is to create a functionally developed layer between physical means of data storage and directly the interfaces used by the application to work with data. The solutions of this class, in addition to the known drawbacks in the form of a decrease in productivity, do not allow to fully reflect the changes in the domain model, since the data is only part of it. To fully support the work of configurable information systems, the storage should allow to store and change the entire domain model, which is currently an unresolved problem. The domain model underlying the configurable information system is a reflection of user actions for obtaining or processing data. Moreover, in reality, the data is inextricably linked with the actions for their receipt and processing. Accordingly, if a user action is used as a basic storage abstraction, then the aforementioned problem can be solved. The database itself, in its classical sense, when using the basic abstraction of user actions, becomes the central link in a configurable information system and an active repository capable of performing these actions to obtain, reproduce, and process the available information. The article presents the results of a study of the current state of science, proposes a fundamental and physical model of an active data warehouse of a configurable system, discusses the issues of its implementation in a schema-free NoSQL DBMS. |
