Event-driven architecture (EDA) is a software architecture paradigm concerning the production and detection of events. Event-driven architectures are evolutionary in nature and provide a high degree of fault tolerance, performance, and scalability. However, they are complex and inherently challenging to test. EDAs are good for complex and ...
SEDA - Staged event-driven architecture decomposes complex, event-driven architectures into stages; Event Processing Technical Society — (EPTS) is an event processing community of interest; Event stream processing — (ESP) is a related technology that focuses on processing streams of related data. Kinetic Rule Language — (KRL) is an event ...
Event-driven SOA is a form of service-oriented architecture (SOA), combining the intelligence and proactiveness of event-driven architecture with the organizational capabilities found in service offerings. Before event-driven SOA, the typical SOA platform orchestrated services centrally, through pre-defined business processes, assuming that ...
In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.
Sequence diagrams are sometimes called event diagrams or event scenarios. For a particular scenario of a use case, the diagrams show the events that external actors generate, their order, and possible inter-system events. [2] The diagram emphasizes events that cross the system boundary from actors to systems.
VIATRA is an open-source model transformation framework based on the Eclipse Modeling Framework (EMF) and hosted by the Eclipse Foundation.. VIATRA supports the development of model transformations with specific focus on event-driven, reactive transformations, i.e., rule-based scenarios where transformations occur as reactions to certain external changes in the model.
A framework for discrete-event simulation in Java, supporting hybrid event/process models and providing animation in 2D and 3D. gem5: C++: Application August 8, 2024 BSD: The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture.

The staged event-driven architecture (SEDA) refers to an approach to software architecture that decomposes a complex, event-driven application into a set of stages connected by queues. [1] It avoids the high overhead associated with thread -based concurrency models (i.e. locking, unlocking, and polling for locks), and decouples event and thread ...
