Which is faster when reading large amounts of data: XML or SQLite

Question

I will be developing a dictionary app for both Android and iPhone. The data will be embedded within the app, and it consists out of approximately 100000 words, with genus and plural form. Is it better to use a SQLite database or can I just stick to XML? Somehow SQLite sounds more efficient, but I thought let's just ask.

Thanks!

Answer 1

That's a bit of an apples and oranges comparison. SQLite is a whole lot more than just a file format. The answer depends on whether you just want to load everything into memory on startup (XML, or better still, CSV will probably suffice), or you want to be able to query the data, in which case SQLite is a far better choice.

Answer 2

You will want to be performing searches, so SQLite will definitely be quicker. You will need some kind of function to install your data from the distributed executable into SQLite, of course...
