[Badari Kakumani]

folks,

in our project we are planning to persistently store some objects.
any recommendations for which modules to use?

anybody used:
app-repository at [url]http://cpan.uwinnipeg.ca/dist/App-Repository[/url] or
object persistence at :
[url]http://search.cpan.org/~vipul/Object-Persistence-0.92/lib/Persistence/Object/Simple.pm[/url]

any pointers/suggestions are greately appreciated.

thanks,
-badari

I have been using Storable for some small things, so no idea if it's ok
for your project.

Hi,

For my experience, Storable is good for both small and big stuffs. But
you should take care of 64-bit platform.

What are your requirements for ACID (atomicity, concurrency, isolation, and
durability)? How many objects, how big, and how often do you want to
manipulate them?

I couldn't get it to install with cpan. It doesn't resolve it's
dependencies automatically, and I ran into a few manually that I could find
on CPAN, so I gave up. I also didn't see much discussion of it on the
web/usenet other than FAIL reports from the CPAN testers and uploads by the
author. I would consider both of those to be bad signs.

Haven't used or attempted to use it.

I like Storable for small thing (or large things that fit in memory and can
be kept a while before writing them back out), and I really like DBM::Deep
for large. I haven't used them where ACIDity was necessary, and suspect
they are somewhat lacking there.

Would an object-relational mapper like DBIx::Class be appropriate?

Are you aware of the Perl object-oriented Persistance mailing list
(poop.sf.net).
