4 Digital Twin Data Hub

A key component of the Digital Twin City platform is the unified information space — a comprehensive data environment that integrates:

• unstructured source and result data;
• a normalized data warehouse comprising:
  • reference metadata catalogs,
  • master data,
  • source and reference time series,
  • matrices of computational models.

This architecture ensures traceability from raw data sources to analytical outputs, maintaining integrity across all stages of data processing — from collection through normalization, modeling, and forecasting to decision-support dashboards.
