In the following example we make a user management system where
|
||
|
|
|
||
|
|
# Each user and group are entities
|
||
|
|
# User is an entity of type 0
|
||
|
|
# Group is an entity of type 1
|
||
|
|
# Each entity (user/group) has 0-1 email
|
||
|
|
# Each entity has 0-* phonenumbers
|
||
|
|
# If an entity is saved all its emails and phonenumbers are also saved
|
||
|
|
# If an entity is deleted all its emails and phonenumbers are also deleted
|
||
|
|
# When an entity is created and saved a current timestamp will be assigned to 'created' field
|
||
|
|
# When an entity is updated a current timestamp will be assigned to 'updated' field
|
||
|
|
# Entities will always be fetched in batches

||
|
