What is the best database (if any) to store large amounts of static data? [on hold]

I have a lot of static data (about 100,000 rows worth) that I want to use in a web app, but I am having trouble deciding what type of database (if any) I should use.

I need to be able to query the data to search for things, but I don't need to do any writes or updates (except for the rare case that mistakes need to be fixed).

Given the circumstances, in what way should I store the data? Should it even be in a database to begin with or should it be stored in another format?
