Figure 3-9. Introducing an email node produces a star graph
Of course, in a real system there will be many more of these emails, each with its intricate
web of interactions for us to explore. It's quite easy to imagine that over time many more
CREATE
statements are executed as the email server logs the interactions, like so (we've
omitted the
START
clauses for brevity):
CREATE
(email_1 {
id
:
'1'
, content:
'email contents'
}),
(bob)-[:SENT]->(email_1),
(email_1)-[:TO]->(charlie),
(email_1)-[:CC]->(davina),
(email_1)-[:CC]->(alice),
(email_1)-[:BCC]->(edward);
CREATE
(email_2 {
id
:
'2'
, content:
'email contents'
}),
(bob)-[:SENT]->(email_2),
(email_2)-[:TO]->(davina),
(email_2)-[:BCC]->(edward);
CREATE
(email_3 {
id
:
'3'
, content:
'email contents'
}),
(davina)-[:SENT]->(email_3),
(email_3)-[:TO]->(bob),
(email_3)-[:CC]->(edward);
CREATE
(email_4 {
id
:
'4'
, content:
'email contents'
}),
(charlie)-[:SENT]->(email_4),
(email_4)-[:TO]->(bob),
