Question

关于数据库设计和其他因素，以下选择中的哪一个更好。

选项1）

class Profile(Model):
    name = CharField(...)
    family_name = CharField(...)
    passport_number = CharField(...)
    ielts = ForeignKey(Ielts)
    education = ForeignKey(Education)

class Ielts(Model):
    reading = CharField(...)
    writing = CharField(...)
    spekaing = CharField(...)
    listening = CharField(...)

Education(Model):
    level = CharField(...)

class Document(Model):
    profile = ForeignKey(Profile)
    ielts_pic = FileField(...)
    passport_pic = FileField(...)
    education_transcript_doc = FileField(...)

选项2）

class Profile(Model):
    name = CharField(...)
    family_name = CharField(...)
    passport_number = CharField(...)
    passport_pic = FileField(...)
    ielts = ForeignKey(Ielts)
    education = ForeignKey(Education)

class Ielts(Model):
    reading = CharField(...)
    writing = CharField(...)
    spekaing = CharField(...)
    listening = CharField(...)
    ielts_pic = FileField(...)

Education(Model):
    level = CharField(...)
    education_transcript_doc = FileField(...)

如果Model（表）的数量很大怎么办？

最好将文件（从技术上来说，文件地址）分发到与其模型相关的不同表中，或者将它们全部收集在其他文档模型中，并对文档模型的每个字段使用外键分别指向其{{1} }？

是否将所有模型的文件字段放在另一个模型中更好？
