Kimball Approach

The Kimball approach, created by Ralph Kimball, organizes data into data marts, which focus on specific business areas like sales, marketing, or finance. It uses a bottom-up approach, where you build data marts first and then combine them into a larger data warehouse.

Kimball works well for businesses that want quick, targeted solutions for specific areas like sales or marketing. It delivers faster results and is easier for non-technical users to use and understand.

How It Works

• Data is structured for easy access using star schemas or snowflake schemas.
• Each data mart handles one specific business process.

Benefits

• Easy for users to query and understand.
• Focuses on fast results for specific needs.
• Quicker to set up for individual processes.

Example

A retailer might create a sales data mart to track revenue and customer purchases. Later, they can add data marts for inventory or marketing to complete their analytics setup.
