The New Rules For Today's Cloud Database Management System
Take the NuoDB 12-question quiz for a chance to win an iPad Mini!
Data affects everything we interact with in technology. Be it a Facebook share, bookkeeping, sending an email, or using a credit card, data is behind it all.
Before our NuoDB database, every relational database had been built on a synchronous, centralized client/server architecture that is incompatible with the notion of elastic scalability in the cloud. We've created an entirely new manner of database management based on a distributed, asynchronous architecture.
Sound really tricky? It doesn't have to be.
This fun and easy quiz will help you understand Read moreit better. These are some of the new rules and capabilities for relational databases for the 21st century.
