/*
|
|
|
|
This migration allows for the storage of all outfit relevant data.
|
|
|
|
Outfit
|
|
- each outfit has one entry in the outfit table
|
|
- each name is unique and ranks are inlined (static 1:n, join unnecessary)
|
|
- faction is limited to 0,1,2,3
|
|
- decal is limited to 0 through 26 (inclusive)
|
|
|
|
OutfitMember
|
|
- each avatar can at most be a member in one outfit
|
|
- each outfit can only have one rank 7 (leader) member
|
|
- rank is limited to 0 through 7 (inclusive)
|
|
- there is a "quick access" index on outfit and avatar for rank 7 (leader)
|
|
|
|
OutfitPoint
|
|
- each (outfit, avatar) combination can only exist once
|
|
- a (outfit, NULL) combination can not be limited yet (not a big deal)
|
|
- deleting a avatar will have his points remain as (outfit, NULL)
|
|
- leaving an outfit will have the points remain as (outfit, NULL)
