extracted from registered data repositories during classification services.

systems and filers over the internet.

networks that was developed by Sun Microsystems and is used primarily by
Unix systems.

administrator. A PEA file defines what applications and users can perform
read, write, delete, query, copy, or hold operations for Centera objects.

files to protect information and audit user actions on files.
PST Files
Personal STorage files are generally used by email programs like Microsoft
Outlook to store user email locally. PST files are also called "composite"
files, because they are packages meant to efficiently store a number of smaller
related files. Another example of a composite file is a ZIP storage file

kinds of files must be preserved for access. Examples of retained files include
files responsive to legal matters and medical records.
Roles
All IS1200 have roles, either admin, auditor, or end-user. If a legal license is
installed, there are also legalAdmin, legalSupervisor, legalReviewer, and
custodian roles. All users have a role, and the role determines what parts of
the IS1200 interface can be seen, and how much of search and report results
are viewed.
