A Semantic Layer is an intermediate layer between data sources and analytical tools that unifies the way data is interpreted across the entire organization. It enables business users to work with the same definitions of metrics and concepts, regardless of the report or application being used.
The Semantic Layer is based on several key principles:
- unification of business metric definitions,
- separation of business logic from source data,
- ensuring consistent analysis results across different tools,
- simplifying data access for business users,
- reducing the risk of data misinterpretation.
The semantic layer helps organizations maintain consistency in reporting and analysis, even when data comes from multiple systems. This enables users to create reports more quickly and make decisions based on unified, reliable information.
