Backend - A solid fundament in the background
A backend is the actual brain of a solution. This is where data is saved, processed and the magic happens. As the name implies all this happens in the background without direct interaction with the end user. Modern backend solutions need to be flexible and scalable to provide a solid operation and allow a continuous expansion.
Frontend - Appealing and user-friendly interfaces
A software is not an end to itself but rather a tool to help business users in their daily work. Therefore, user have to interact with the so called frontend. Good frontend solutions do not only show information but also have a corporate appearance and allow a simple and intuitive usage.
