问题 I am about to start developing a "time machine" for windows. I need to store a lot of records in a table. Every time I perform a backup I will write about 50,000 records because that's how many files I have in my computer (each records has nothing to do with storing a file. the record will contain the path where each file is located) Anyways I don't know if I could use XML to store my records since my queries are not going to be complicated plus it is easier to deploy versus creating a local
