a few changes for the naming conventions ("_" prefix might be interpreted as "private" rather than "link to")

     243A word about naming conventions:
     244 * for table names:
     245   - resource tables are capitalized
     246   - binary relation table names are composed of the capitalized resource name, an underscore and:
     247     - the capitalized resource name of the targeted resource, for a relation
     248     - the lower case field name, for a property
     249 * for column names:
     250   - capitalized if referencing the key of a resource
     251   - lower case for a property
    245253It starts to become interesting when we start to consider the versioning aspect of the above. We're going to add ancillary tables for storing the information related to the change itself (the //event//) and the recording of the changes.
    248256CREATE TABLE TicketEvent (
    249257       uid              integer PRIMARY KEY,
    250        _ticket          integer REFERENCES Ticket (uid),

     264CREATE INDEX TicketEvent_created_idx ON TicketEvent (created);
    259267CREATE TABLE TicketChange (
    260268       uid              integer PRIMARY KEY,
    261        _tevent          integer REFERENCES TicketEvent (uid),
     269       TEvent           integer REFERENCES TicketEvent (uid),
    262270       field            text,
    263271       oldval           text,
    264272       newval           text,

    267 CREATE INDEX TicketChange_tevent_idx ON TicketChange (_tevent);
     275CREATE INDEX TicketChange_TEvent_idx ON TicketChange (TEvent);
    269277The `<Resource>Change` table is clearly inspired of the existing `ticket_change`: we don't want to replicate all the complexity of the ticket relational model in dedicated versioning tables, because it would be clearly overkill. We're not interested in //querying// these values anyway, only in storing them for displaying them whenever we're going to show the history of the resource.
    274282CREATE TABLE TicketEventComment (
    275283       uid              integer PRIMARY KEY,
    276        _tevent          integer REFERENCES TicketEvent (uid),
    277        inreplyto        integer REFERENCES TicketEventComment (uid),
     284       TEvent           integer REFERENCES TicketEvent (uid),
     285       Inreplyto        integer REFERENCES TicketEventComment (uid),
    278286       comment          text
    280 CREATE INDEX TicketEventComment_tevent_idx ON TicketChange (_tevent);
     288CREATE INDEX TicketEventComment_TEvent_idx ON TicketEventComment (TEvent);
    281289-- comment should be FTS indexed
    284 It's easy to see that if we'd like to extend the ticket event comments by addinng "custom" fields, we would just have to add them in the above table if they're of the 1-to-1 type, or using property/relation secondary tables if they're of the 1-to-m type (#2961).

    286294And of course, the comment events are themselves versioned!
