[EVALUATION] - E04 - jamPersist Evaluation Case Applied to Ruby

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

The above thread was exceptionally productive.

http://laz.../case/lang...

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

-

The next (more practical) evaluation is persistence:

http://laz.../case/persist/...

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

http://laz.../case/persist/s...

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.ruby...

Rails.ActiveRecord:
http://ar.rubyon...

any other solutions for ruby persistency?

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.

http://www.ruby-talk.org/cgi-bin/scat.rb/ruby/ruby-t...

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://laz.../case/lang...

jamPersist.Ruby.??? is the second step:
http://laz.../case/persist/...

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?f...
http://rubyforge.org/softwaremap/trove_list.php?f...

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:

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/proje...), Lafcadio
(http://lafcadio.rub...), Criteria ([not an ORM, but a layer for SQL
abstraction] http://mephle.or...), Madeline, Pstore, and KirbyBase
pop immediately to mind.

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

Maybe he should start looking on the RAA.

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.

seems to be in development.

status: alpha.

-

http://enigo.com/proje.../tutorial/why_use_it.html

contains SQL code.

missed requirement: transparency

-

product rejected.

> Lafcadio (http://lafcadio.rub...)

"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
> abstraction] http://mephle.or...),

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/proje.../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?

"
http://laz.../case/persist/...

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

http://laz.../case/persist/s...
"
