如果你存储一个文件指针，这意味着你需要在每次你想读取字符串时做文件I / O。一些句子不是很长，你可以总是使用长文本数据字段，如果你需要。显然你的数据库会有点大，因为你有文本，但是没关系。这肯定是一个比存储文件更好的选择。

It should be fine to store the string in the database. If you store a file pointer instead, that means you need to do File I/O every time you want to read the string. A few sentences isn't terribly long and you can always use a longtext data field if you need to. Obviously your database will be a little bit larger because you have the text, but that's ok. It is certainly a better alternative than having to store the files.
