"Most mainstream database technologies, whether relational, graph, or document-oriented, keep the latest state of the data, throwing away the old data when it changes. In contrast, EventStoreDB, the leader in the emerging class of databases, called Event Stores, is specifically designed to keep the changes along with the business context of those changes, in the form of events. Current state can then be derived from replaying the event stream. This pattern enables a myriad of benefits, including powerful audit, debugging, caching, occasionally connected scenarios, and much more."
