[EVALUATION] - E03 - jamLang Evaluation Case Applied to Ruby
http://groups-beta.google.com/group/comp.lang.ruby/msg/412943e7c6ed6968

The above thread was exceptionally productive.

http://lazaridis.com/case/lang/ruby.html

[as it looks, i will take ruby as the "reference" and compare other languages against it]

···

-

The next (more practical) evaluation is persistence:

http://lazaridis.com/case/persist/index.html

there are ready evaluations of another products, thus you can understand the sequence easier, e.g.:

http://lazaridis.com/case/persist/schevo.html

you can simply take the above sequence and apply it to the library / product that you suggest for ruby persistency.

[alternatively, you can just suggest the library/product to use - or provide a pointer to listing]

I am a little disapointed about the feedback in this thread.

I am aware about 2 products:

Nitro.Og
http://nitro.rubyforge.org/

Rails.ActiveRecord:
http://ar.rubyonrails.com/

any other solutions for ruby persistency?

As it looks, I will make the evaluations by myself.

Thanks for any postive assistance so far.

Ilias:

There are numerous solutions for Ruby persistance. See
[ruby-talk:130871] for a long list that I provided you on the 14th of
February.

I think that it's high time you start trying to implement something --
a lot of the things that you're not "getting" will make sense when you
try to implement something, rather than asking everyone else to do
your homework.

this is not complete information (see below).

Please do not twist the facts.

I like to collect concise information, which I reuse to present it to other intresents, thus I reduce their learning and research curve.

jamLang.Ruby is the first step:
http://lazaridis.com/case/lang/ruby.html

jamPersist.Ruby.??? is the second step:
http://lazaridis.com/case/persist/index.html

step for what?

To showcase (busy) evaluators within 20 min. the superiority of ruby.

in a direct, quick and simple comparison to other languages / systems.

···

-

This should be of intrest for the ruby community.

A simple give an take.

But as it looks, I have to do all the work myself.

I've looked at rubyforge:

http://rubyforge.org/softwaremap/trove_list.php?form_cat=66
http://rubyforge.org/softwaremap/trove_list.php?form_cat=68

just ActiveRecord and Og seem to be relevant for this evaluation.

All the information you are looking for is easily available here:

Just in case this is not enough, a good resource for more information is here:

This should be of intrest for the ruby community.
A simple give an take.

How many evaluators have already used your evaluations, do you have any major references to show the relevance of your studies?

But as it looks, I have to do all the work myself.

That's true, you should try to do your work by yourself, you cannot expect others to do your work for free.

I have skipped a lot of this thread. However, if you are talking about
persistence layers, there are MANY more than that.

Kansas (http://enigo.com/projects/kansas\), Lafcadio
(http://lafcadio.rubyforge.org), Criteria ([not an ORM, but a layer for SQL
abstraction] http://mephle.org/Criteria\), Madeline, Pstore, and KirbyBase
pop immediately to mind.

There is no 'give' from you Ilias, you are just pootling amay at
'EVALUATION's nobody will ever read. Like you have been for years.

If people want to know about Ruby they could ask on the list quite
easily. We put up with any number of questions, you are living proof
of that.

Good idea.

Indeed. I named a number of these in the message which Ilias so

Maybe he should start looking on the RAA.

product rejected.

Lafcadio (http://lafcadio.rubyforge.org)

"It currently supports MySQL. in the future it will support a wide range of databases."

missed requirement: support multiple databases.

product rejected.

, Criteria ([not an ORM, but a layer for SQL

SQL-centric: rejected.

Madeline, Pstore, and KirbyBase pop immediately to mind.

requirements: stable or at least a beta, transparency, multiple datastores.

?

(still, just ActiveRecord and Og pass the initial requirements)

AR is in development, too. I should probably update that info, but the fact
is that Kansas is a lightweight, simple, stable system with fairly few
"unimplemented features" (my buzzword for bugs used across a veriety of
production applications, in one version or another, for well over a year
and currently servicing several million transactions a day. So, it
probably should not be listed as alpha, though the version number will stay
low because it isn't what I want it to be, yet.

As for "Contains SQL code". What are you talking about?

sodiums = dbh.select(:Chemicals, :Manufacturers) do |c,m|
(c.chemical_name =~ '%sodium%') && (c.manufacturer.name =~ '%flynn%')
end

chlorides = dbh.select(:Chemicals) {|c| c.chemical_name =~ '%chloride%'}

sodium_chlorides = sodiums & chlorides

sodium_chlorides.each {|x| x.chemical_name = x.chemical_name.upcase}

That hardly looks like SQL.

yes, you should change this.

I've provide a link:

http://enigo.com/projects/kansas/tutorial/why_use_it.html

I've overflow the document - and have overseen "The ordinary way".

You should possibly focus on the strength of your product, and show immediately this compact code:

"
def getData
   result =
   application.dbpool.getConnection do |ksdbh|
     ksdbh.select('DailyNav').each do |nav|
       result.push nav
     end
   end
   result
end
"

would you like to try the evaluation template?

there are ready evaluations of another products, thus you can understand the sequence easier, e.g.:

I have looked at a fair lot of these ORM, and Kansas is probably the
one that forces you to write least SQL of all (for real-life
applications, at least).

When others direct you at helpful links, try reading the document
instead of "overflowing" it then making knee-jerk posts. The "Ordinary
Way" section is a detail of what is necessary *without* Kansas (or
some other ORM layer). It is _immediately_ followed by the improved
code Kansas instead allows you to write.

I've been lurking on this thread and giving you the benefit of the
doubt, Ilias. But this sort of "research" confirms the suspicions of
others. You are at best lazy, trying to get others to do your work; at
worst a troll.

I think I've figured it out: he's actually an Eliza program. This would easily explain his inability to produce truly original or thoughtful responses. And when the Eliza program hits a dead end, we get "please avoid further off-topic comments."
