Maintaining Persistence

[djam]

I'm wondering what is the best way to maintain persistence for a small software program I'm working on. I need to track some contact information. Should I be saving these as XML files? Parsing text files? This program is for a PDA and resources are limited, I don't want to parse a file and store them as objects in RAM until I exit the program and write it to a file. What is the best way to do this?

thanks

Well - if the minimum size a file occupies is 65kb, it will be equal if your file uses 200 bytes or 2000 bytes.

If a xml-api is already installed, there isn't much to save here too.

How complicated is your information to store, and how complicated might it get in future?
If there are only few, plain values, I would go for a kind of .ini - or ...rc - format - simple text with name=value pairs.

If you use some indirection, you may start with a simple-text format, and replace it with an xml-format when needed:

Application -> (uses) -> Configurater -> uses plain iniFile
Application -> (uses) -> Configurater -> uses xml-File

When updating, you know that the single point to modify is your Configurator.

Some PDA OSs have their own database interfaces like the Palm OS. I haven't done much programming using it, but I'd look there to start.
