Cortex Analyst

Snowflake Cortex Analyst & Semantic Layer

Snowflake Cortex Analyst enables natural language queries on enterprise data — but it requires accurate semantic metadata to work reliably. DE Copilot generates the business definitions, field context, and governance metadata that powers a trustworthy semantic layer.

The Metadata Layer Behind Cortex Analyst

Cortex Analyst is only as accurate as the semantic metadata it reads. DE Copilot generates that metadata from your STTM and business rules — ensuring business context is captured, governed, and kept in sync.

Business Definitions

Field-level business definitions, domain context, and plain-language descriptions — generated from STTM metadata and kept in sync with the actual data model.

Semantic Model Generation

Table relationships, join paths, measure definitions, and dimension hierarchies — derived from the Canonical Metadata Model and structured for Cortex Analyst consumption.

Data Dictionary Integration

Auto-generated data dictionaries provide the field-level context that Cortex Analyst needs to interpret natural language queries accurately.

Natural Language Query Accuracy

When semantic metadata is accurate and complete, Cortex Analyst produces reliable SQL. DE Copilot ensures the metadata layer is governed, traceable, and up to date.

AI-Assisted Semantic Enrichment

The AI layer suggests business synonyms, common query patterns, and semantic relationships — enriching the metadata model beyond what is explicitly documented in the STTM.

Governed Semantic Layer

All semantic metadata passes through human review before it is published to the Cortex Analyst semantic model. Engineers validate business definitions before they power natural language queries.

Build a semantic layer that actually works.
