I'd just take that as favorite tool for the job, SQLite's pretty interchangeable. Also, if you've already gotten a database engine running, it's probably best to just keep everything there. Otherwise, you get into the situation I was in at a previous job in which certain page loads from an app written before I started there required a sun jsp app for the main part of the page, which made requests to pull some data from an Oracle database, some data from an apache mod_perl app that queried from a mysql database, some data from an apache mod_jk app that pulled from a c++ app with its own database format, and some data from an apache mod_jk app that stored and retrieved from a postgresql instance. Everything was nice and well-documented, but mein gott was that a lot of moving parts.
