Event-driven architecture prioritizes system events and changes, with small units programmed to quickly respond to them. It doesn’t predict user movements and can be used in machinery for safety.
Event-driven architecture is a type of computer and software development architecture that prioritizes system events and changes. There are usually parts in programming done specifically to find changes and respond directly to these changes or to pass them on to other sections. The event-driven architecture doesn’t try to predict the user’s movements, so this might be better for a user performing unconventional functions. It is normally used in a computer, but can also be used to control machinery.
There are many types of system architectures, and each prioritizes certain functions or operations. With event-driven architecture, events and changes are the top priority. For example, when the software goes from a resting state to being used, it is a change to the system. Other changes can be power alterations, use of different tools, adding code and other similar events. Whenever something requires more power or resources, or if new data needs to be discovered, this is considered an event.
To make it easier to find and respond to changes, there are typically small units programmed into the software or system that are made for just this purpose. Many of these parts are capable of responding directly to an event by changing power or doing whatever the user needs. Other parties are made to find the change and pass the information on to parties that can respond to it. These parts tend to increase the speed of the system, because they are made to quickly change the system for the needs of the user.
Other types of computer architectures typically try to predict user functions based on the top priority of those architectures. While this can be effective, it could slow down the system or misuse computer resources if the user doesn’t work according to priorities. With event-driven architecture, no predictions are made, so an unconventional user can take advantage of it.
Most computer architectures are only meant to be used on a computer, but event-driven architecture can also be used in machinery, usually as a safety precaution. During the use of the machinery, there are often many changes from the change of the motor, the movement of the actuators and the running parts. Event-driven architecture usually does not optimize these movements, but supervises them. For example, if a part moves in a way that could be potentially dangerous, this architecture will stop the motion to protect the operator and bystanders.
