Relations

ServiceNow allows four different forms of relations between entities.

• References directly on the entity. See References for details.
• Related Lists. squid by arc46 supports a subset of these. See Related Lists for details.
• Relations. These are typed M-to-N relations defined by ServiceNow. See Relations for details.
• M-to-N Tables. These may be ServiceNow defined M-to-N tables (e.g. cmdb_rel_team, sys_user_grmember or cmdb_ip_address_dns_name) or any custom table that implements a M-to-N structure. See M-to-N Tables for details.

References are always rendered if defined in a configuration.

All other relations require additional database access and are only retrieved when explicitly requested.
