Identify the missing word(s) in the following sentence within the context of Microsoft Azure. Database security can get complicated for applications with many users. In order to make it easier for both administrators and auditors, most database applications use role-based security. Microsoft SQL Server contains several fixed database roles within each database for which the permissions are predefined. Users can be added as members of one or more roles. These roles give their members a pre-defined set of permissions. These roles work the same within Azure SQL Database and SQL Server. Users who need administrative access to the database can be made members of the role [?]. Members of this role can perform any action within the database by default.
