What is Dimensional Modeling
This article explores dimensional modeling, a data modeling technique used in data warehousing to optimize querying and analysis. It explains the importance of dimensional modeling in simplifying data models and enabling faster query performance, and discusses key components such as dimensions, facts, relationships, star and snowflake schemas, and conformed dimensions and facts. It also covers the critical considerations when designing a dimensional model, such as choosing between star and snowflake schemas, designing for performance, and creating data marts with dimension and fact tables.

What is Star Schema
This article explains what a star schema is, how to design one, and how to query it using SQL. A star schema is a type of database modeling technique used in data warehousing that organizes data into a centralized table called a fact table that is surrounded by multiple dimension tables. It simplifies the structure of the data, making it easy for analysts and business users to understand and access it.
