What is the Advantage of a Relational Database?

By Placing the Data into Logical Modular Constructs, I can create Building Blocks for large Data Queries

Linking these Building Blocks together in an infinite number of ways allows me to focus on the data I need

By only requiring the Computer Host to process the linked data (as opposed to all the data) it can process the data faster with fewer resources
