DBG

我真的好讨厌网站开发,花Q.

User(id: int~)   # 主键 id, 使用 sequence
{
    openid    : TextStr?                   # 可空
    account   : NameStr!                   # 唯一。
                                           # 后缀描述符可叠加 例如 account: NameStr?!
    password  : NameStr
    permission: Permission
    sex       : Sex         = Sex.unknown  # 默认值
    nickname  : NameStr?
    repr{
        id, nickname, permission
    }
}

Item(id: int~){
    name: NameStr?
    cost: int

    repr = all
}

Course(id: int~){
    location: NameStr?
    time_seq: TinyStr

    repr = all
}

Some(id: int~){
    name: NameStr!

    repr{

    }

}

User^ <-> Item{     # 一对一关系, User对Item具有所有权
    some: NameStr?  # extra data
}

User <<->> Course{  # 多对多关系

}

User <<-> Some{     # 多对一关系

}
