Events vs Notifications
Download as PPTX, PDF0 likes657 views
Event is an object that describes a state change in an application or system. It is generated by some user or automated activity. Event listeners register to receive notifications of events and take appropriate actions. Notifications are messages or alerts sent by an application to notify users, either within the app or as push notifications when the app is not open. Notifications are used to encourage users to try features, alert them to non-critical issues like updates, or prompt them to enable push notifications if beneficial. Events and notifications are both mechanisms for asynchronous communication in applications and systems.
Events vs Notifications
- 2. What is Event? Event is an object that describe a state change in a source. It gets generated as a consequence of some user activity, or scheduled activity on Frontend or Backend of an application. e.g. User gets added or deleted in the application. Applications can be developed to have an event-driven architecture (EDA), which means its behavior revolves around event detection, event forwarding and event handling. Event Source – An Object that generates an event is called source of event. This can be Manual or Automated. Event Listener – The process or application which register for events and listen to it when the event occur and takes some action.
- 3. What is Event? Events are actions or occurrences that happen in the system you are programming — the system produces (or "fires") a signal of some kind when an event occurs, and provides a mechanism by which an action can be automatically taken (that is, some code running) when the event occurs. An event, in a computing context, is an action or occurrence that can be identified by a program and has significance for system hardware or software.
- 4. What is Event? Event is an action that occurs as a result of the user or another source, such as a mouse click. An event handler is a routine that deals with the event, allowing a programmer to write code that is executed when the event occurs. Events are sent by the publisher class and received by the subscriber class.
- 5. What is Event? Many programs spend most of their time waiting for something to happen. This is especially true for computers that work directly with humans, but it’s also common in areas like networks. In programming and software design, an event is an action or occurrence recognized by software, often originating asynchronously from the external environment, that may be handled by the software. Computer events can be generated or triggered by the system, by the user, or in other ways. Typically, events are handled synchronously with the program flow; that is, the software may have one or more dedicated places where events are handled, frequently an event loop. Use cases: •Asynchronous systems with asynchronous data flow •Applications where the individual data blocks interact with only a few of the many modules •Loosely coupled applications
- 8. Foreground Events Foreground events are those events that require user interaction to generate. In order to generate these foreground events, the user interacts with components in GUI. When a user clicks on a button, moves the cursor, and scrolls the scrollbar, an event will be fired. Background Events Background events don't require any user interaction. These events automatically generate in the background. OS failure, OS interrupts, operation completion, etc., are examples of background events.
- 10. What is Notification? Notification is a kind of message, alert, information or status of an application that is pushed to user on web or mobile devices. The purpose of a notification is to notify the user about a process that was initiated in the application either by the user or the system. This article could help someone who’s trying hard to create a notification for developmental purposes. Notification is instance of notifying, making known, or giving notice
- 11. What is Notification? An app notification is a message or alert sent by an application to the device user. They include push notifications and in-app notifications. The main difference between in-app notifications and push notifications is implied by their names. In-app notifications are only visible within the app while the user is engaging with it. Push notifications on the other hand do not require the application to be open and messages are displayed on the screen of the mobile, even when the device is locked. Sending people the right amount of notifications is a balancing act, and overdoing it is bad for user experience.
- 12. Notifications could be of various types : 1.Status Bar Notification (appears in the same layout as the current time, battery percentage) 2.Notification drawer Notification (appears in the drop-down menu) 3.Heads-Up Notification (appears on the overlay screen, ex: Whatsapp notification, OTP messages) 4.Lock-Screen Notification (I guess you know it) The initial approach to notification design needs classification on three levels: high, medium, and low- attention, i.e., “levels of severity.”
- 13. What is the difference between an alert and a notification? Alerts are enabled by the user and are triggered by driving events like speeding, harsh braking, and entering/exiting a geofence. Notifications are set up by the user and are triggered by specified alerts to send an email, SMS text, or a push notification via the mobile app.
- 15. Why we need notification? •Suggestions: Notifications can be used to encourage users to try out new features or products to encourage them down the marketing funnel, but again these should be appropriate and targeted to each user. •Low level alerts: If you want the user to take an action, for example to install an update, but it is not critical – then in-app notifications are better as you are not interrupting them unnecessarily. •Prompt to enable push notifications: If you feel that it would be more beneficial to the user to receive them, then you can prompt them to enable them, but do not do it too much as it will just annoy users.
