ralfbecher/orionbelt-semantic-layer
API-first semantic layer engine with MCP server that compiles declarative YAML models into optimized, dialect-specific SQL across PostgreSQL, Snowflake, ClickHouse, Dremio, and Databricks.
This tool helps data professionals define their business metrics and dimensions in a clear, consistent way using YAML files. It takes these definitions and automatically generates optimized SQL queries tailored for various databases, enabling consistent reporting and analysis. Data analysts, BI developers, and data engineers will find this useful for managing complex data models across different data platforms.
Use this if you need to standardize how business metrics are defined and queried across multiple data warehouses or lakes, ensuring everyone gets the same numbers regardless of the underlying database technology.
Not ideal if your data is only stored in a single database and your team is already comfortable writing direct SQL queries for all analytical needs.
