Does anyone have an idea for an architecture with a hosted

If you look at various rich internet applications, the software and the
database are often both hosted.  That is how gmail works as well as
emerging hosted word processing applications and other ajax web
pages/apps.  There might be an option of pulling the data down to your
PC, such as by using popmail in combination with gmail or e-mailing a
document to yourself, but there is no option on where you store your
data when interacting with the application.

We often use client-based applications with client or server data
persistence (e.g. Word) in addition to the hosted applications with
hosted data.  I am looking for any examples of hosted browser-UI
database applications where the user indicates a data source that can
be anywhere accessible on the internet.

This is more likely in the SQL world, but I'm not looking for database
independence -- the specific database tool can be fixed.  I'm looking
for database-location independence in an application hosted as a web
browser application.

I would like to write a piece of software that can be used by anyone
but where I host the app and not the database software or data.  If
someone wants to use it, they need to have a database somewhere (of
whatever type is required by the application) and the application will
take the data source specification as input.  I might want to use a
service-oriented architecture where the read and writes to the database
are not with a direction connection, but I have not seen a example of
that either.

In case I haven't said this right yet, it would be a free for use,
no-installation required, database application where the database is or
possibly where to put the database if it is not already there.  People
could then use the very same application, but have completely separate
databases.

There might be more issues than I would want to tackle to do this, but
I'm curious whether there are examples or not.  Thanks.  --dawn



Hi Dawn.

I might be stating the obvious or misunderstanding your requirements but surely what you are describing is "Web Services" and SOAP?
