Identify Actоrs аnd Use Cаses fоr the fоllowing specificаtion of a software system: A Digital learning environment is being designed for use in schools for students from 3 to 18 years of age. It is a framework in which a set of general-purpose and specially designed tools for learning may be embedded, plus a set of applications that are geared to the needs of the learners using the system. The framework provides general services such as an authentication service, synchronous and asynchronous communication services, and a storage service. The tools included in each version of the environment are chosen by teachers and learners to suit their specific needs. These can be general applications such as spreadsheets, learning management applications such as a Virtual Learning Environment (VLE) to manage homework submission and assessment, games, and simulations. They may also include specific content, such as content about the American Civil War and applications to view and annotate that content. The approach adopted is that this is a distributed system in which all components of the environment are services that can be accessed from anywhere on the Internet. There is no requirement that all of the learning tools are gathered together in one place. The system is a service-oriented system with all system components considered to be a replaceable service. Identify at least 4 different actors and 5 different use cases. For the use cases also indicate who are the participating actors. Make sure to use appropriate naming for actors and use cases.
