Request-based

A request-based system or process operates primarily in response to specific demands or inquiries. It relies on users, clients, or other external entities initiating actions or providing input to trigger events, retrieve information, or initiate tasks. This contrasts with systems that operate autonomously or continuously. The efficiency and effectiveness of a request-based approach hinges on clear communication, well-defined procedures, and a robust mechanism for processing and fulfilling incoming requests, ensuring timely and accurate responses.

Request-based meaning with examples

• The online library's search function is request-based; users submit queries to find books, articles, or other resources. The system processes the request and returns the results. This design allows efficient use of resources, only retrieving information as needed, improving its resource management compared to an information dump on the user and a continuous monitoring database.
• Cloud computing services often operate on a request-based model. When a user needs to deploy a server instance or access data, they send a request to the provider. The provider then allocates the resources and delivers the requested service. This flexible system provides excellent scaling benefits.
• The customer support system for the mobile application is request-based. When a user experiences a problem, they submit a support ticket, which is then processed by the support team. The support team reviews the ticket and responds as needed. They can filter incoming issues more efficiently this way.
• A web server handles requests from web browsers on a request-based approach. When a user clicks on a link, the browser sends an HTTP request. The server processes the request, retrieving the page and sending it back to the browser. The entire design revolves around this fundamental action.
• Many file sharing protocols are request-based; users request files from a server, the server fulfills the request by making the files available. This allows for efficient management of the shared files as only requested data is transferred, not all data.
