BI Semantic Layer Generator
Overview
Generates semantic layer definitions for BI tools from dimensional models. This skill automates the translation of dimensional models into platform-specific semantic definitions.
Capabilities
- LookML generation (Looker)
- Tableau data model generation
- Power BI semantic model creation
- Cube.js schema generation
- dbt metrics layer integration
- Calculation and measure definitions
- Hierarchy generation
- Security filter generation
- Join path optimization
Input Schema
{
"dimensionalModel": "object",
"targetPlatform": "looker|tableau|powerbi|cubejs|dbt",
"businessGlossary": "object",
"securityRules": ["object"]
}
Output Schema
{
"semanticModel": "object",
"calculations": ["object"],
"hierarchies": ["object"],
"securityFilters": ["object"],
"documentation": "string"
}
Target Processes
- Metrics Layer
- BI Dashboard Development
- Data Warehouse Setup
Usage Guidelines
- Provide complete dimensional model definition
- Specify target BI platform
- Include business glossary for consistent naming
- Define security rules for row-level filtering
Best Practices
- Maintain consistency between semantic layer and source models
- Use business glossary terms for user-facing labels
- Implement hierarchies for drill-down analysis
- Configure appropriate caching strategies
- Document calculation logic for maintainability
