Introduction to Play Framework
Play Framework is a Java web framework that aims to improve development efficiency over traditional Java web frameworks. It allows for automatic compilation and deployment, integrates with databases using JPA, and supports features like REST, templates, and asynchronous programming. The documentation provides an example of generating a new Play application, connecting it to a database, writing tests, and creating models, views and controllers to build out the application.
