    <p>I wrote a script to use active_record without rails. My tests are on windows 7 (Trendmicro Virus protection enabled - can't disable it because the notebook is property of my company), Lenovo T520. I wrote a little tk script that started in about a second. I added the 'sqlite3' gem and it started in 2 seconds.</p> <p>After requiring the 'active_record' gem startup time when up to 30 seconds!!</p> <p>Can I do something against that (please don't recommend changing the os)? Is ruby just for use with rails so that it can run on a unix box where the performance is ok?</p> <p>Versions are: ruby 1.9.3p125 (2012-02-16) [i386-mingw32] activerecord (3.2.2)</p> <p>Edit: Something interesting happened. After starting the script a few times "requiring 'active_record'" is done in 0.53 seconds. Maybe it's os-caching or virus protection ignores the files because it considers them safe. After a fresh reboot the time went up to 3.5 seconds on the first run and dropped again on the second run to the known 0.53 seconds.</p>

    1. COHave you tried [DataMapper](http://datamapper.org/) instead of ActiveRecord? Ruby is fine for general scripting but ActiveRecord isn't exactly lightweight or quick to start up.

      1. USmu is too short
    2. COOk, requiring just dm-core boils it down to 12 seconds. That is almost acceptable. But somehow I'm still annoyed. I thought writing a an data centric application on windows with a scripting language like ruby would be completely possible. But I'm struggling already at step zero. I understand, that I have to pay for a orm framework. But 12 seconds just to start it up without doing anything with it is a pain in the ass (at least while developing).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
