Foundation: Understanding the Semantic Layer

The semantic layer in TimeXtender Classic bridges raw data and business intelligence tools by transforming structured data into business-ready formats through semantic models. These models organize tables, relationships, and calculations into logical structures that mirror real-world business concepts, enabling self-service analytics while maintaining data governance.

Key benefits include:

  • Simplified analytics: Non-technical users can work with business terms instead of raw database schemas
  • Centralized logic: Measures, hierarchies, and security rules are defined once and reused across tools
  • Multi-tool support: Deploy models to multiple BI platforms simultaneously

Supported endpoints:

  • Analysis Services (SSAS): Creates Tabular or Multidimensional cubes compatible with Power BI and Excel
  • Qlik Sense/QlikView: Generates QVD files and scripts for optimized data loading
  • Tableau: Produces TDS metadata files and SQL views for direct connectivity
  • CSV & Database Tables: For simple data exports or integration strategies.

Semantic models act as a translation layer between the data warehouse and visualization tools, ensuring consistency across reports while abstracting technical complexities. This approach enables organizations to maintain a single source of truth while supporting diverse analytics needs through flexible deployment options.
