Eventträd

Eventträd is a theoretical concept in computer science, particularly within the realm of event-driven architectures and reactive programming. It proposes a data structure that organizes events in a hierarchical or tree-like manner. The fundamental idea is to represent a complex system's observable events as nodes within a tree. Each node can represent a specific event, and its children can represent subsequent or related events that may occur.

The structure of an eventträd allows for efficient querying and processing of event sequences. By traversing the tree, one can identify patterns, trigger specific actions based on event chains, or filter events based on their position within the hierarchy. For example, a root node might represent a user login, with branches representing subsequent actions like profile viewing, item selection, or logout.

Applications of the eventträd concept can be found in areas such as real-time analytics, complex event processing (CEP) systems, and the development of user interfaces where sequential user interactions need to be managed and responded to. While not a universally implemented standard, the principles behind eventträd inform the design of many modern event-handling systems, promoting a more structured and manageable approach to complex event flows. The term itself is a portmanteau of "event" and "träd," the Swedish word for tree.
