Dimension Tables

Dimension tables are specialized tables in a database that store descriptive information about different aspects of data, such as dates, products, or locations. They provide context and labels that help interpret and analyze the main data in fact tables. For example, a sales database might have a fact table with sales transactions, and dimension tables for products, customers, and time periods. These tables make it easier to organize, filter, and understand complex data by breaking down details into manageable, labeled categories.
