A Mendix app consists of app-level documents and a number of modules. Each module can contain many documents. At the app level, there are some settings and documents that apply to your app as a whole. For example, navigation is a app-level document; the menu bar is app-wide and can refer to functionality in all modules. Most documents, however, live at the level of a module.
App settings include the languages for the end-user, app directory and database and server settings.
See App Settings.
At the app level you can change the security level, manage user roles and manage administrator and anonymous user access.
See App Security.
In navigation you can configure the menu bar and navigation tree for your application. Also you can specify what the home page is, as in, the page you see right after signing in.
