Web application development is the process of creating software programs that operate via web browsers over the internet. These applications are accessed by users through their browsers, making them highly accessible and versatile.

Front-end development focuses on crafting the user interface and experience using HTML, CSS, and JavaScript to create visually appealing and interactive elements.

Back-end development involves designing the server, database, and application logic that manage requests from the front-end, process data, and deliver responses.

Database management is crucial, with developers using various databases like MySQL, MongoDB, and PostgreSQL to store and retrieve data efficiently.
