Ask HN: Online database service for collaboration?

What might a physically distributed team use by way of a database? Something that could, like filemaker or access (or, indeed, any database, but I mention those because they are more usable by less technical users), be set up with tables according to the project at hand, with e.g. form input access for workers of a certain type, table data access for others, etc. A google spreadsheet isn't really sufficient, and building our own app just for this purpose seems unnecessary if this service exists.

I appreciate any help you can offer to point me in the right direction. Thanks.
