Database or XML files for a simple to-do web app?

Question

I'm trying to design a simple ajax based to-do list web app.. is a database good for this type of application, or xml files better for storing data from the app?

Any tips would be helpful.

Answer 1

Although XML is very handy for small sum of datas, it is not intended to replacing database.

How big your datas gonna be? do you want to delete old to-do list or keep it? cause you can't feel too much different in performance between XML and database for just one thousand records. for more than 10.000 records, choose database.
database is more easy for adding or deleting records, filter and find some record than XML.

In the AJAX world, I use database for storing my data, convert it to XML and display it with XSLT spice.

Answer 2

I'm pretty sure a database would be better, if you have one to spare. Getting things out of a database seems much easier than reading files for everything, and it's probably no slower. Good night!

while you're doing this to maintain your qualifications cutting-edge, then use whichever technologies you're least attentive to. while you're at it, evaluate SQLite. that's a superbly small relational DB that's attainable for many systems, and the source code is freely attainable.
