This chapter presents the user access maintenance procedures.
TerraAmazon has a multi-user environment. Many users can simultaneously access and work on the same database. In order to increase security for the database, TerraAmazon has two user levels in terms of access privileges: Operator and Administrator.
The Administrator User has full access to all the menus. Every database has at least one Administrator, created along with the Conceptual Model. This is the user that creates Operator Users, as well as other Administrator Users. He is responsible for every procedure presented on this User´s Guide. This role should be attributed only to trained personnel since the Administrator user can cause permanent data loss if a mistake is made.
The Operator User has limited access to the database. There is no access to the entire Administration menu and to some options from the layer´s menu, opened by the right-click on layers. This user cannot remove layers, edit locked vectorial layers or delete objects from layers. Operator users have access to spatial operations with layers, layer creation from themes and can only perform vectorial editions on the active projects or unlocked layers.
The correct attribution of roles among the users is one of the keys to database security.
