Odoo Community and Odoo Enterprise have a different structure. In the following we will explain the two user interfaces (backends) roughly. This includes navigating to the apps and within the apps, loading different languages ??and changing a user.
BACKEND IN ODOO COMMUNITY
The top navigation shows the activated apps in Odoo Community. By clicking on a navigation point, you get to the respective app. Once there, you will see the internal navigation of the app on the left side. To load a new app, also go to the top navigation, click on "Apps", select the appropriate app and click on Install. To change the language or the user, go to "Settings" in the upper navigation and then "User" or "Load a translation" in the left navigation (the latter also applies to Odoo Enterprise).
BACKEND IN ODOO ENTERPRISE
The backend of Odoo Enterprise is completely different to Odoo Community, as the top navigation not only serves as navigation between the apps, but also as internal navigation of the respective app. You can access an app by clicking on the left "App Icon" in the upper navigation and then on the corresponding app (Icon).
Once you are in the app, the top navigation is the internal navigation of the app. Click on the links to get to the subareas of the app.
