I would save the info of visitors on my website and I would know the best way for make it.
These are info about visitors:
IP, User-Agent, Page Visited, TimeStamp
The operation who I could make are :
Write a new guest
Read All Guest
Order by TimeStamp
Group By Page Visited and count
Count for timestamp interval`
If I'll use a simple file on disk without DB? Also NoSql DB could be used, because I have a VPS!
