In this article by Brian Ritchie, author of the book RavenDb When most people talk of a database, they mean a relational database. Relational databases have been the foundation of enterprise application for the past 30 years. First defined in June 1970 by Edgar Codd of IBM's San Jose Research Laboratory, relational databases store data in now familiar tables made up of rows and columns.
Relational databases have served us well for many years, so why do we need a different kind of database? Most developers have experience of building applications with relational databases and access to great tooling. However, relational databases do have their limits. As our systems grow, it becomes more difficult and expensive to scale a traditional relational database.
To understand how we got here, let's take a quick trip back into the recent past. Relational databases were created when big iron ruled the world. These centralized mainframes provided the foundation of the first relational database systems. As we moved into the client/server era, these databases moved onto lower priced servers. But fundamentally, they are still running on one central machine.Read A Different Kind of Database in full
