Semantic Layer Glossary
Clear definitions for the terms that matter most in modern analytics, AI, and the semantic layer — from AtScale.
CoCo
Snowflake's conversational AI assistant that lets business users ask natural-language questions and get answers governed by Horizon Context and Semantic Views — announced at Summit 2026.
CoWork
Snowflake's personal work agent (formerly Snowflake Intelligence) that reasons across data, automates multi-step workflows, and takes governed action — built on Horizon Context and Semantic Views.
Semantic Optimization
The ongoing practice of measuring accuracy and compute cost as first-class metrics across AI and analytics workflows, then tuning the semantic layer so the warehouse runs the cheapest correct path for each question.
Snowflake Semantic View
A native Snowflake database object that defines metrics, dimensions, and relationships inside the warehouse — the governed foundation for Cortex Analyst, CoCo, CoWork, and Cortex Sense.
Snowflake AI Readiness
A readiness framework for assessing whether your Snowflake stack can support governed agentic AI — covering semantic governance, Horizon Context, Semantic Views, and cross-platform consistency.
Snowflake Horizon Context
Snowflake's governed semantic and context layer — built on Horizon Catalog — that stores metric definitions and activates them for CoCo, CoWork, and every Snowflake consumer.
Put the semantic layer into practice
AtScale for Snowflake delivers a governed semantic layer that makes every term in this glossary a reality — one definition of truth, across every tool and AI agent.
