Choosing a Data Model for the Digital Twin of Environment

A review and analysis of available data models presented. Based on the analysis of data models, it concluded that the most appropriate data model for the digital twin is the UniData company model, which allows storing information about any object in one table. The proposed data model for the digital twin reflects spatial and temporal properties of the data; stores a set of independent but interconnected objects of storage. As needed, new objects can add to the digital twin without changing the data model and access tools. The design of individual objects of the digital twin can be spaced apart in time and distributed among developers. It becomes possible to integrate data from different domains more easily. All this simplifies the design, development, creation, and operation, accordingly, reduces costs of implementing these processes. It is possible to present the measured data in points (including in the form of time series), profiles, and grid point. Model is easy to use, does not depend on the used Database management system and operating systems.
