What is a State-Transition Database?
State-Transition Databases store not just your data, but the different transitions your data goes through over time. State transitions are events that record not just what’s changed, but why it changed in the order those changes occurred. This creates a permanent, unchangeable log of all the transitions the data has gone through.
They don’t overwrite your data, so no data is ever lost. Each state-transition event is stored in a stream that can be read or queried as needed. You can move up and down the stream of events, giving you new insights and the power to make better, more informed decisions that you can trust.
|Subscriptions give you real time changes
|Data can be overwritten, needs verification
|Save changes once, subscriptions propagate changes instantly
|Data needs to be recorded then changes pushed out to the system
|Stop and start self-validating streams as needed
|Needs to be rebuilt gracefully in line with other systems
Event Driven Architecture
|Build complex workflows and react in real time
|All solutions need to consider the different forms of data
|Move through the event stream in any direction for analysis and forecasting
|Not always easy or possible, changelogs might be needed
Root Cause Analysis
|Trace events back to their roots, making analysis easy and faultless.
|Refer back to changelogs, check external data sources, piece together information
|When older systems need replacing, do it at your pace.
|Needs long term planning, down time and to happen all at once.
Why use EventStoreDB?
Businesses today are driven by digital events happening in real time. An event in one area of the business triggers a response in an app that runs another. These apps and services must respond constantly, without delay or data loss. Scale is mission-critical because there are thousands or even millions of events occurring every minute of every day. Without a single, foundational database of these events, today’s apps and services can’t work. Failure is inevitable. EventStoreDB is the only native event database that provides the record of events to support these new apps and services.
