Final answer:
The three key characteristics of web-based software engineering are functionality, usability, and scalability.
Step-by-step explanation:
The three key characteristics of the engineering of web-based software engineering are:
- Functionality: Web-based software engineering focuses on creating software that performs the desired functions and tasks effectively and efficiently. This involves designing user interfaces, implementing features, and testing the software to ensure it meets the functional requirements.
- Usability: Usability is an important aspect of web-based software engineering. It involves designing software that is easy to use and navigate, providing a seamless user experience. This includes considering factors such as user interface design, accessibility, and user feedback.
- Scalability: Web-based software engineering requires engineers to create software that can handle varying levels of workload and user traffic. This involves designing and implementing scalable architectures, utilizing appropriate technologies, and optimizing performance to accommodate growing user bases and increasing data volumes.
