\item As mentioned, most modules facilitate uploading and managing of document files. These features can be accessed by file managers as known from modern \myacfp{dms}.
The file manager \myac{ui} allows
handling large and numerous files of various file types of file \emph{repositories}. A repository represents the virtual file system of a module’s root entity item.
Preset folder structures can be pre-configured per system module.
Files can be instantly searched for and merged for download in \myac{pdf} format. Data consistency is always assured
in face of simultaneous access. Instead of uploading, directories containing a large number of files can be imported from the server file system in order to make them available online.

\item A query editor is provided to compose and execute complex queries instantly. It constrains structured \myac{sql}-like database queries using criterion term as building blocks
and guides users with syntax
highlighting and locations of syntactic or semantic errors. Virtually any object attribute is available as a query criterion, meaning users can search for anything they ever entered
into the system. Queries can be saved in order to provide them to other users.
%The query editor is a generic component available to all Phoenix \myac{ctms} modules.
The proband module’s query editor allows expressing a trial’s eligibility criteria to retrieve matching subject candidates.

\item A journal available to items of each module shows the history of changes, which are logged by the system (audit trail).
In addition, manual entries can be created to log events related to the item.

\item Independent of journal system messages, notifications of events such as reminders are generated for individual recipients.
Selected notifications will be sent to enabled email addresses of recipient identities.
The history of notifictions can be browsed and obsolete notifications are revoked.

\item Multi-client capability is supported throughout all modules by the separation into \emph{departments} and the option to configure global and department-level user roles.
Each department corresponds to a trial site. The sovereignty of \myac{pii} stored in the proband database is given by cryptographic means for each department.
