For a great, off-the-shelf database solution for your mobile devices, try out General DB. It lets you download and import text files, databases, or SQL files. You can then view, edit, or delete your rows, or add more rows, or create views, execute queries, and much more.
Private DB is a similar app but is read-only which prevents your users from tampering with the data in the tables you distribute.
Some reviews from the App Store:
May be basic, but it's great!

I wanted a simple database that kept track of the books I've read - the titles, the authors, the dates, and a synopsis. The fact that it is searchable, and modifiable, is a real bonus. Of course, I could've added many more fields if I needed. This is definitely worth the $2.99 upgrade. Thanks for developing this.
Exactly what I was looking for

I hand you a tab delimited text file, you parse it into a database with good interface and searchability. Tried the free version, bought the upgrade instantly. Robust, well thought out, instantly understandable.
Very cool and useful too!

I needed a way to track simple bits of data that would later help me make assumptions. This little app did the trick. Just what I wanted. I see I can export to cab which means I can share the data. Very cool and useful tool for my iPod Touch.

I am a truck driver in the oilfield. I travel to alot of leases that are very rual with no specific address to identify their location. This database is exactly perfect for my needs. It lets me label the oil company that owns the lease and then allows me to input multiple sub-data bases under it. Example: oil company- lease name plus fields for lease number, tank size, destination, and also has an awesome GPS feature to pinpoint exactly where the lease is located with a stickpin on the map. On top of all this it sorts by several fields of user choice and has a search feature to find a sub-database in a single tap. I personally think this database app is worth way more than a mere $2.99. Thank you, an extremely satisfied customer, Peggy

Just downloaded the free version and effectively created my own mini app (to track all the conference calls i do in a day) in less than 10 mins. Absolutely brill, exactly what I was looking for.
Excellent & Flexible

I use this data base every day for my courier business. Its ideal for keeping track of jobs, mileages, rates, quotes etc and for checking against receipts and invoices later. Features like hitting the "now" button automatically enters the current time & date making it fast enough to use in the field. I can easily email myself a .csv copy to keep a backup from within the app. I'm looking forward to promised improvements on next update
Just the job!

Perfect. Just what I was looking for. Having bought 2 other apps that were far too specific and complex this does exactly what I wanted. Lists from scratch were just so easy but had a bit of difficulty importing existing Excel lists but received excellent customer service. Thanks.
