A web application is an interactive software system that runs over the internet and is accessed through a web browser without needing installation. Unlike desktop or mobile apps, web applications operate using real time communication between the browser and server, making them accessible on any device with an internet connection.

Examples of web applications include ERP systems, CRM platforms, online reservation systems, payment gateways, e commerce systems, admin dashboards, SaaS tools, analytics platforms, and custom business applications. Web applications combine both frontend (user interface) and backend (server logic) components.

A professionally developed web application helps businesses automate operations, optimize workflows, securely manage data, and deliver powerful user experiences. Key advantages include scalability, customization, multi user access, security, and easy integration with other systems.
