Generative AI Fundamentals

本课程讲授如何构建能够记忆的 AI 智能体——既能在一次对话中记忆，也能跨会话记忆——并使用 Databricks Lakebase 作为持久化后端。学员将了解 LangGraph 的 Checkpointer 系统如何提供短期记忆（会话内的对话连续性），以及 LangGraph 的 Store 如何提供长期记忆（跨会话的用户偏好），二者均由 Lakebase Autoscaling 支撑。学员将在 notebook 中构建并测试这些记忆系统，通过 MLflow 跟踪观察智能体行为，并将一个完全有状态的智能体部署为 Databricks App。

In this course, you will learn how to design, implement, and govern catalog structures and large-scale data organization on the Databricks Data Intelligence Platform. It offers a comprehensive view of Unity Catalog as the centralized governance layer for an enterprise lakehouse. Divided into five modules, it begins by placing Unity Catalog within the cloud deployment model — covering the Account Console, metastore creation, and the administrator role hierarchy. You will then translate organizational topology (business units, regions, and dev/QA/prod environments) into a scalable catalog and schema design using naming conventions, ownership patterns, and MANAGE delegation. The course then covers secure storage integration with storage credentials, external locations, the managed-storage hierarchy, managed versus external tables, and UC Volumes for non-tabular data. Next, you will apply access patterns and isolation strategies — the three-level GRANT chain, workspace-catalog binding, and schema-level Attribute-Based Access Control (ABAC) policies — to enforce fine-grained data protection at scale. Finally, the course closes with best practices for catalog design, automation, least-privilege permissions, and group-based access management.

本课程教授学生如何使用 MLflow 的评估框架对 AI 智能体进行系统性评估，以应对传统软件测试无法处理的非确定性 AI 系统所带来的独特挑战。学生将评估一个已注册在 Unity Catalog 中并通过 Unity Gateway 调用其模型的共享工具调用智能体，使用内置评判器处理正确性和安全性等常见标准，使用准则评判器满足特定业务需求，并使用自定义评判器应对专项需求。本课程涵盖使用精选数据集进行离线评估和在线生产监控，包括在 Unity Catalog 中存储 MLflow Traces。学生将使用 MLflow Tracing 了解智能体的执行模式，并收集来自开发人员和主题专家的人工反馈，这些专家通过 Databricks App 对智能体进行审查。通过实践演示和实验，学生将掌握创建评估 Workflows 的技能，从而在 AI 智能体开发生命周期中持续推动质量提升。
