EventStoreDB is a database for storing data as a series of events and being able to rebuild the current state of these events. It’s an approach to building applications by focusing on storing the state changes that occur. Projections are a feature that allows you to react to changes in the Continue Reading

Reading Time: 3 minutes In the last post, we saw the difference between a Rule Engine, Event Stream and Complex Event Processing. In this post, we would try to dig a bit deeper into what is CEP. There are a lot of events happening in the enterprise. If these events are routed through an intelligent system that can find the correlation between the events and then take proactive action Continue Reading
Reading Time: 3 minutes Recently, there has been a lot of talk about CEP and the benefits that it can bring to the industry. CEP is the analysis of event data in real-time to generate immediate insight and enable instant response to changing conditions. Likewise, a seemingly similar concept is that of Business Rule Engines. These again work in enterprises and help in triggering actions on the basis of Continue Reading
