CS411 Handouts, Assignments, Mid & Final Term Past Papers are discussed below. Graphical user interfaces and the event-driven approach as they relate to desktop, web, and mobile applications are the topics of this course. It builds from the ground up using what you already know. It’s a practical course. .. In order to understand the material, you should focus on completing programming exercises because we will be using examples in class.
An event is something that happens within a specific system or domain. There are two interpretations: an actual occurrence and a computer-world detection that corresponds to it. A single event may capture “one” occurrence, but numerous events may each catch “some” of the real occurrence. Probabilistic occurrences, for example, may or may not be connected to actual events. an instance of fraud detection during a banking transaction. An event-object is a representation of every event. There are many different kinds of events, and information on each sort of event includes specifics.

Such as a key press or file event. Consider the example of a coffee shop. There are constantly happenings. With this example, let’s examine synchronous versus asynchronous behavior. In the event that a completed order, prepared coffee, and cooked pastries arrive before the subsequent order for coordinated behavior. Take computer system events as an example. On a computer, interruptions and exceptions, e.g. Subtract zero. sensors used to monitor the patient. Car sensors that sound an alarm in case of low oil pressure. monetary alerts. road tolls. Etc. The act of performing computations on events is known as event processing.
Reading, creating, altering, and deleting events are examples of frequent event processing processes. Event-based programming, also known as event-driven architecture, refers to the design, development, and operation of programmed that employ events, either directly or indirectly. Why not? Event-driven programming is not required. We’ll poll people about events. You still wait for events even if your application is not event-driven. Blocking is waiting for a single event at a time.
Before the subsequent operation can begin, synchronous operations must be finished. Asynchronous procedures. Why should we use event-based applications. They are simpler to climb. Suitable for Visual development environments with numerous GUI components and event sources. It directly maps to the real world. It is deterministic, meaning that a real-world scenario and its representation have an exact mapping in the system for processing events. The event processing system provides a rough, if imprecise, picture of the actual world.
What kind of events can therefore be found in non-real time applications. events from the keyboard and mouse, extra GUI elements, files, and message-based events. The decoupling concept underlies events. Let’s contrast request-response based design with events. While requests beg for something to happen, happenings have already taken place. Service requesters get in touch with clients or service suppliers. Event producers send events to event consumers in event-driven architecture. What are the benefits of each depiction of a request, an event, or an order from a client?
Lesson Learning Objectives
Align the pupils with the newest software development technologies.
- Pupils ought to have a strong background in programming.
- Microsoft should be well-known to students. using the Internet
- It should be possible for students to tackle any programming issue relating to. Net.
- Switching to any other Microsoft.net version that has been put into use ought should be possible for students.
An event producer is an entity that generates new events for the system at the edge of an event processing system. EVENT CONSUMER: An event consumer is an entity that receives notifications of events from an event processing system at its edge. An event that is introduced into an event processing system by an event is referred to as a “raw event.” producer. DERIVED EVENT: A derived event is one that is created as a byproduct of event processing. This occurs within an event processing system.
MANAGEMENT OF STATELESS OCCASIONS When an event processing agent operates in a stateless fashion, its reaction to one event is independent of its response to subsequent ones. STREAM THEATRE An event stream (or stream) is a grouping of linked events.
The events in the stream are frequently in a clearly defined timestamp-based order, which is known as a chronologically fully ordered collection. A A heterogeneous event stream permits the possibility of several sorts of occurrences, whereas a homogeneous event stream requires all events to be of the same type. Following are some event agents.
During this lecture, C# will be covered. Let’s start with a brief history of Java and J++ before that. Microsoft wished to expand Java in order to connect it to COM. Sun did not want the Java platform to become dependent in this way. Microsoft desired a pristine Java implementation. A clean-room implementation is what? Reverse engineering a design and then replicating it without violating any of the copyrights and trade secrets connected to the original design is known as “clean room design,” commonly referred to as the “Chinese wall technique.”
Should we utilize “change events” instead of sending a request to query the state, for example. Events can be deemed to have significance apart from their creators and recipients, but requests cannot. events can. Push events frequently have only one direction. Producers and consumers are separated by events. Asynchronous event processing is a possibility.
There might be several customers, and each will understand it in a unique way.
