Re: [Modeling-users] Request for specific adaptors?

[Mario R. <ma...@ru...>]

I have recently felt that an adaptor to a non-relational db server would
be very nice -- useful for simple applications (and installations of)=20
and/or
quick prototyping, but will allow that the same application be easily=20
"scaled-up"
to a relational server (with no changes to the data model).
This does not equate to simple object persistence (e.g. any of several
such schemes available, from pickle to zodb, etc.). It is also not about
performance ;-!. It is about giving a very high-level separation between
the application objects, and the back-end, that will also allow=20
switching
between SQL and non-SQL storage. I am in particular thinking of
something like bsddb, with string values (rows) that are simply=20
repr(dict).
Then searching and filtering can still be achieved without modifying
any client code (albeit very inefficiently!). The advantage is that
small applications that do not do so much searching and filtering
do not suffer very much, and they can be installed a lot simpler
(requiring only to make sure to have write access to some directory,
as opposed to setting up an sql server). But, the power of the model
is still at hand, on which the application can build...
