Editing HCL Notes (section)

===Client/server===
Notes and Domino are client/server database environments. The server software is called Domino and the client software is Notes.  Domino software can run on Windows, Unix, [[AIX]], and IBM mid-range systems and can scale to tens of thousands of users per server. There are different supported versions of the Domino server that are supported on the various levels of server operating systems. Usually the latest server operating system is only officially supported by a version of HCL Domino that is released at about the same time as that OS.

Domino has security capabilities on a variety of levels. The authorizations can be granular, down to the field level in specific records all the way up to 10 different parameters that can be set up at a database level, with intermediate options in between. Users can also assign access for other users to their personal calendar and email on a more generic reader, editor, edit with delete and manage my calendar levels. All of the security in Notes and Domino is independent of the server OS or Active Directory. Optionally, the Notes client can be configured to have the user use their Active Directory identity.
