Microsoft Fabric is a unified, end-to-end analytics platform that combines data integration, engineering, warehousing, science, real-time intelligence, and business intelligence into a single SaaS offering. Built on OneLake — a centralized data lake that stores all data in open Delta/Parquet format — Fabric eliminates data silos and enables seamless collaboration across teams. The platform uses a capacity-based pricing model measured in Compute Units (CUs), where workloads consume from a shared pool of resources. Understanding Fabric's item types (Lakehouse, Warehouse, Notebook, Pipeline, Semantic Model, etc.) and how they interact through OneLake is essential for building scalable, governed data solutions.
