Does Ruby has any default database with it?

I will do webpage scraping using Ruby and required Gems. But looking for
a capable database into which I can store the data,which I will fetch
from the script.

Thus asking if Ruby has any inbuilt one or suggest me if any open-source
DB,which is capable with Ruby?

Thanks

Normally sqlite is the go to being that it’s the default of rails. Check
into sequel.

Doesn’t Rails come with a built in database called Brick? No additional
set up required. Supposed to be out of the box I believe.

No, you might be thinking about WEBrick, the web server that’s a
default Rails component, but that’s totally irrelevant to the OP’s
question.

To the OP: you can use MySQL, SQLite, PostgreSQL, etc.

Also, MagLev has built-in object persistence, but it’s still at 1.8.7.

@Hassan

Are all of the above - “MySQL, SQLite, PostgreSQL” open-source? Any good
documentation to use with “SQLite, PostgreSQL” would you like to prefer?

Thanks

Yes. Really, the choice depends on your use case(s), platform, and
personal preference so I’d just try them all :slight_smile:

Good luck.

Fairly sure MySQL and Sqlite are OS. Then again, much more than that and
you really should be googling for documentation to these types of
things.

I need 4 tables with more or less 40,000 rows in each,which must be
capable of producing report data as export in excel or CSV. Need to run
all kind of SQl queries into it,to get rows.

Thanks

what good is your help hasan if you are going to complain about it

rails comes with sqllite < it is official, but you can set easily any
dataengine you like

sql lite is the gig

Didn’t get your point @Strauss

Hey look at that, finally someone with the right answer.

See also: SDBM

However which of these are available will depend on your Ruby
implementation, unfortunately

Outside of Ruby, sqlite is probably the easiest to get started with if
you are already familiar with SQL.

Though if you don’t know raw SQL you’re in for some troubles. Study sql
and
play with it for a while before you try making anything expansive. One
hours planning is worth 10 hours of frustrated coding.

@Brandon - I am 3 years of experienced with Oracle Sql,PL-sql. So Sql is
not a big deal for me. The worried point is, which database should I
choose. :slight_smile:

PostgreSQL or Sqlite would be what I’d recommend.
sqlite would be the easiest to get up and running with.

Making sure. You can never tell some times.

Sqlite is good for quick databases, MySQL for midrange, and postgre
seems
to be getting a lot of credit for large but I haven’t personally used
it.

Yes,bug Ruby : SDBM documentation is not good. Only list of method
mentioned,but not a single example with them.

Geez, how could I forget SDBM???

https://github.com/ruby/ruby/commit/66796b4c7efefc71a9fe9c085d4669df0bb4e672#ext/sdbm/init.c

So actually there is documentation, but it’s not showing up on
ruby-docs.org or rdoc.info.

I think the best course for a new project is to start simple, go with
sqlite, if you find you need more performance or some particular
feature, bump up to postgresql. mysql is pretty common, but there are
concerns about its future under oracle. That said, there’s no shortage
of opinions everywhere.

The Sequel gem is probably a good place to start, since it sounds like
you’re well of in SQL programming:
https://github.com/jeremyevans/sequel/#readme

Even with that, it can take a bit to understand the Ruby that goes
around it, so I’d suggest experimenting a bit, do some prototypes to
figure out what you need, throw them away and then design, write your
tests, then write your app code.
