Welcome to Amazon RDS (Relational Database Service)! We've covered storing files, but applications often need to store structured data—like customer info or product catalogs. This is where relational databases shine.
Think of a database like a digital filing cabinet that can instantly find and update information.

Have you worked with relational databases before?
A relational database organizes data into tables with predefined rows and columns, much like a spreadsheet. The "relational" part means you can create links between tables, for example, linking a Customers table to an Orders table.

Relational databases like those in RDS provide ACID properties—Atomicity, Consistency, Isolation, and Durability. This means your transactions are reliable: either all parts of a transaction complete successfully, or none do. Your data stays consistent even with many users accessing it simultaneously.
This reliability makes RDS perfect for applications where data accuracy is critical, like financial systems or inventory management.
