Don't know if it helps, but some suggestions might be as follows (if you allow on-line database, not the one hosted on your own computer, I suppose such online database management services provide option to download (and save for safety) a back-up copy of data):
Free Commons plan — all data public
Up to 15 users can edit data
Up to 100,000 entries per application
Choose your database name
No encryption, attachments, logo or custom colors
otherwise (data not public, etc.) you pay USD 24 per month - I suppos (http://dabbledb.com/pricing
1000 records in free plan only
you would need a paid plan
another kind of option...
just build a very simple Website and embed a database or Excel file with your database built on your computer...
there will be no "search" feature available (directly on the website) for users...
you will have to change (replace) the database file (made available on the Website) whenever you want it to be available in up-to-date form...
some people do this...
I think someone is making available a good database of tugs on his Website, but I do not remember the address now...
one of the many free of charge opportunities to build and host a website is:
( see also: http://sites.google.com/site/projectwikitemplate_en/
upload your database file (whether it is a spreadsheet (eg. Excel file) or database file) for sharing onto one of services like this:http://member.thinkfree.com/member/goLandingPage.action
here you give users some kind document (your database) of search capability on-line... not perfect but bether than nothing...
you might use also Google Docs, see:
...or any of several other similar free services on the Web...
remember (paid) zoho from point no.2 ?...
zoho is a kind of "online office application suite"
from "suite" (for your declared task) the best will be either database (online) apllication or spreadsheet application...
other similar (to zoho) options are discussed here:

but in any case (of using online office applications) I would build two databases pararelly (one in onlie office application and one - as a "back-up copy") on my own computer...
