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.
