I’m not sure if this will meet your requirements, but there is
Kirbybase
https://github.com/manveru/KirbyBase
Pure ruby flat file
database. I’ve used it before, but not for a while: I thought it had
vanished.

PStore and probably not , from what I can tell PStore relies on loading
the entire file into memory, so I think that a Derby under something
like DataMapper should work well enough at least for local personal data

I’m guessing that your needs will exceed its capabilities…
but have you looked at PStore? Its major plus is that it’s included with
the Ruby standard library by default.

thanks, I actually talked to Neo4j , again onerous license, you better
have VC if you want to do anything commercial although they did say that
“they would look the other way” , contractually you on the hook .
Dolphin is actually quite interesting , i had studied building
something along those lines using memory pipes for local interchange

You’d probably want the java binding and not the ruby binding. I’ve been
thinking about using https://github.com/andreasronge/neo4j [6] , which
shouldnt be hard to embed . I’ve not yet tried either.
Another
possibility is trying to get
http://open-dolphin.org/dolphin_website/Home.html [7] working with
jrubyfx. Here the idea is that you have a desktop app with views written
in javafx on the client and the controllers, database, etc running in a
seperate process or on a server.
Anyways, just thought I’d toss a
few more possibilities at you.

For relational, Derby is nice because it actually ships with java

out of the box now. Lately I’ve been using Titan with
Cassandra
embedded on the back end (accessed through the pacer
gem), and it has
been awesome stuff so far. I’m not qualified to
weigh the pros and
cons of graph vs relational across the board,
but coming from a
relational background, I’m really happy with
graph at the moment. Hope
this helps!

hi all,
I’m looking for an
embedded database that I would use for jrubyfx desktop app. Ideally it
would be the same database that I would use for a common repository but
it probably wont’ be since I want to use Heroku add ons or other PaaS. I
guess push come to shove I can do Amazon.
I went back to
the Jruby book and that basically was about using rdms via ActiveRecord
which is ok but not ideal. If I went down that path I know I could use
Derby which is embeddable and can be run also in network mode. Packaging
Derby with the app is painless. There’s of course sqllite and given that
every OS out there basically supports it including iOS and Android it
might make a great choice but again ActiveRecord. Yes, there’s a mobile
component as well to my effort so that context is a consideration.
Coming from a strong Object Db background an object db with
tranparent semantics would be great but I can’t seem to find one. I
don’t want a in-memory db strategy. The datasets locally will be large
enough that you would not want to load the entire db into memory.
I have looked at TouchDB which has CouchDB and Couchbase
Server as network counterparts but that seems to be a bit up in the air
and not sure how much that buys me. Frankly, ActiveRecord looks
cleaner.
As I write this i bump into db4o by Versant
which had a Smalltalk OODMS, looks great, its Java based so hooking it
up to JRuby should be do-able. but its GPL which is a problem because
the project is a low priced app for sale and making the licensing costs
will be well probably impossible for a few years if lucky.
Anyhow I’m getting stuck looking for the perfect fit, I figured some
here may have gone done the same path. Of course JRuby integration is
key. Any feedback is appreciated.
thanks
Charles M.
