Data Warehouse Schema

A data warehouse schema is like a detailed blueprint for organizing stored information. It structures large amounts of data from various sources in a way that makes it easy to analyze and retrieve. Think of it as a well-organized filing system that categorizes data into tables, relationships, and categories, enabling businesses to efficiently generate reports and insights. Common schema types include star and snowflake models, which optimize data for quick queries and comprehensive analysis. Essentially, it’s a structured map helping users find and interpret data efficiently within a data warehouse.
