In this eBay Tech talk, Raimo explains how you can use EventSourcing and Command-Query-Responsibility-Segregation in order to create a scalable software that can be evolved according to the needs of your business.

One table with three columns; with eventsourcing, that's all you need to develop an e-commerce system, or a crm app, or basically every application you can imagine.

Instead of saving the state of an application like we're used to, we're capturing domain events: everything relevant that happened in your application. The state of your application is inferred from these events at runtime.
