Code Block

language	text
title	How to read in/out/direction
collapse	true

How to read "from"/"to" and "direction":
- the "in" node is "vserver"
- the "out" node is "tenant"

Code Block

language	text
title	How to read the label
collapse	true

How to read the "label":
- ("out" node) "label" ("in" node) i.e. tenant "owns" vserver

Code Block

language	text
title	How to read multiplicity
collapse	true

How to read "multiplicity" of "One2Many":
- ("in" node) cardinality is "one" i.e. Each "tenant" has one "vserver"
- ("out" node) cardinality is "many" i.e. Each "vserver" has many "tenants"

Code Block

language	text
title	How to read contains-other-v
collapse	true

How to read "contains-other-v":
- traversal of ("out" node) includes data for ("in" node) i.e. traversal of "tenant" includes data for "vserver"

Code Block

language	text
title	How to read delete-other-v
collapse	true

How to read "delete-other-v":
- delete of ("out" node) includes does nothing to ("in" node) i.e. delete of "tenant" includes does nothing to "vserver"

Code Block

language	text
title	How to read SVC-INFRA

How to read "SVC-INFRA":
- ?

Code Block

language	text
title	How to read prevent-delete
collapse	true

How to read "prevent-delete":
- delete of ("out" node) is prevented when related to ("in" node) i.e. delete of "tenant" is prevented when related to "vserver"

General Applicability

EdgeRules only apply to "relationship-list" relations in the schema, since the referenced object could be anything
EdgeRules do no apply to sub-component relations in the schema, since this is implicit and hard-coded behaviour
