ISBN: 9798170548637 - building ai-ready semantic layers: governing metrics for llms and data agents: implement dbt metricflow, cube cloud, and snowflake semantic views for consistent ai and bi analytics (1 Ergebnisse)

Taschenbuch. Zustand: Neu. Neuware - Build a semantic layer that gives BI tools, LLMs, and data agents the same governed business meaning.Giving an AI model access to a warehouse does not guarantee analytically correct answers. Valid SQL can still use the wrong metric, join at the wrong grain, duplicate revenue, misinterpret time, expose restricted data, or produce a different answer from the company dashboard.This practical guide shows how to move stable business logic out of prompts and ad hoc queries and into governed semantic models. You will learn how to design metrics that remain consistent across traditional analytics and AI systems, then implement and operate them with dbt MetricFlow, Cube Cloud, and Snowflake Semantic Views.- Model grain, entities, primary keys, joins, facts, dimensions, measures, and semantic contracts correctly- Prevent fanout, chasm traps, duplicate aggregation, unsafe distinct counts, and ratio errors- Build simple, ratio, derived, cumulative, and conversion metrics with governed time semantics- Implement semantic models with MetricFlow, Cube Cloud, and Snowflake Semantic Views- Prepare metrics for LLMs with descriptions, synonyms, AI context, verified queries, literal resolution, and domain routing- Connect semantic services to applications and agents through SQL, REST, GraphQL, SDKs, and MCP- Design governed MCP tools for metric discovery and semantic querying instead of unrestricted raw SQL- Combine structured analytics with document retrieval, search, and multi-step agent reasoning- Protect AI analytics with RBAC, row security, masking, tenant isolation, identity propagation, and least privilege- Defend against prompt injection, tool misuse, semantic model poisoning, data exfiltration, and unsafe write actions- Test metric behavior with semantic unit tests, paraphrase evaluations, regression suites, and cross-engine contract tests- Control caching, pre-aggregations, materializations, query fanout, latency, concurrency, and agent cost- Govern metric ownership, certification, versioning, deprecation, drift detection, and multi-platform synchronizationThe guide includes extensive SQL, YAML, Python, Shell, JSON, and GraphQL examples that connect semantic concepts to realistic implementation, testing, security, agent integration, and production operations.You will also learn how to build a production semantic trust chain so that transformations, metric definitions, execution engines, access policies, BI tools, and AI agents stay aligned around the same approved business definitions.Grab your copy today and build analytics systems where AI flexibility works on top of governed, testable, and consistent business semantics. …
