M3 uses an elaborate, hierarchical  security  scheme that enables the librarian to assign levels of access for Cataloging, Circulation,  Windows  OPAC, and database maintenance features. Security in M3 is implemented through the use of the M3

Group Editor. The M3 Group Editor creates, customizes,  and modifies  the group permissions required to gain access to M3 functions. Groups are created with cus- tomized sets of parameters  and privileges. The three default group types are patron, item, and special reserve. An unlimited number of each group  type can be created.

 

M3 has many security measures in place to protect the integrity  of the databases. Each module is accessed using  a login  name and password.  Records  that are marked for deletion  are not removed from  the database until a purge  is performed. Various utilities, such as indexing and data repair, are available to the adminis- trator if a problem  arises in the databases.
