11. Online Survey System

One of the best ways to start experimenting and putting your knowledge in a hands-on project is by working on an Online Survey System. The project aims to build a platform that can collect the opinions of the target audience via the internet. This is especially useful for market-research companies that perform analytics on the data collected. So, if you feel like this seems like a simple project, remember that it has a significant scope.
In this application, only authenticated users can express their opinion on a particular issue or topic. Once the users submit their views, the app will collect this using a checkbox. It will then automatically evaluate the opinions and display the result at the end of the survey. Since the study is conducted online, it eliminates several hours of manual labor, along with a significant reduction in survey costs.
