TIBCO (The Information Bus Company) was founded in 1997 by Vivek Ranadivé as a subsidiary of Reuters Holdings. [2] Ranadivé originally developed the information bus software at his previous company, Teknekron Software Systems, which he sold to Reuters for $125 million in 1994. [3] TIBCO's software allowed companies to receive and respond to ...
Event processing is a method of tracking and analyzing (processing) streams of information (data) about things that happen (events), [1] and deriving a conclusion from them. Complex event processing ( CEP) consists of a set of concepts and techniques developed in the early 1990s for processing real-time events and extracting information from ...
Spotfire was founded by Christopher Ahlberg and Ben Shneiderman to develop applications of dynamic queries in the early 1990s. Ahlberg returned to Sweden and developed an enhanced UNIX implementation of his visual data analysis tool, the Information Visualization and Exploration Environment (IVEE). Spotfire was launched in mid-1996 by IVEE ...
A finite-state machine ( FSM) or finite-state automaton ( FSA, plural: automata ), finite automaton, or simply a state machine, is a mathematical model of computation. It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some inputs; the ...
TIBCO Hawk provides a distributed agent-based extensible system which allows the monitoring and control of system and application software components. There are 3 main components: Hawk Event Service, which provides the ability to store and retrieve events via a database. Hawk Agents include a non-inferencing, event-driven rule engine to filter ...
An event driven architecture may be built on four logical layers, starting with the sensing of an event (i.e., a significant temporal state or fact), proceeding to the creation of its technical representation in the form of an event structure and ending with a non-empty set of reactions to that event. [6]
A discrete-event simulation ( DES) models the operation of a system as a ( discrete) sequence of events in time. Each event occurs at a particular instant in time and marks a change of state in the system. [1] Between consecutive events, no change in the system is assumed to occur; thus the simulation time can directly jump to the occurrence ...
In computation, a finite-state machine (FSM) is event driven if the transition from one state to another is triggered by an event or a message. This is in contrast to the parsing-theory origins of the term finite-state machine where the machine is described as consuming characters or tokens. Often these machines are implemented as threads or ...
