Client-Server Architecture

The client-server architecture [2], which is also known as two-tier, is a system with several clients (usually over the network) that connect to a single server. The clients may send requests to the server, the server sends back replies.

Applied to the current project, the server would contain the data, i.e. the tasks (Data Access Layer). Then, one ore several clients would have to connect to the client to modify tasks or add tasks to the todo-list.
