I am trying to write a webapp, where one of the functionality is to exchange messages. I am trying to understand how to store these messages. I do not want to store it in DB. If i have to store in file, then how do i separate between messages.
Any links to some document would be greatly appreciated. I tried googling a lot but could not get hold of any reference
You should think about storing the messages in XML format, and use your webapp to load and parse those XML files into the message objects. Why do you not want to store the messages in the database? There are serious drawbacks to storing in the file system rather then the database (or even system memory).
