mongoDB使ってみた。
どんなもんだろうなーと思ったので試してみた。
環境はDebian Squeeze
インストール
Debianなので本家サイトのやり方に従ってパッケージで入れる。
キー追加。
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
リポジトリ追加。
$ sudo vi /etc/apt/sources.list
行末に追加する。
deb http://downloads-distro.mongodb.org/repo/debian-sysvinit dist 10gen
インストール。
$ sudo apt-get update $ sudo apt-get install mongodb-10gen
動作確認でシェル実行。
$ mongo MongoDB shell version: 1.8.1 connecting to: test
INSERT的なこと
db.<テーブル名的な>.insert(<保存データJSON>)でできるっぽい。
テーブル作る的なことはしなくてもデータ格納時になければ勝手に作ってくれるみたい。
データ保存する
> db.users.insert({ name : 'test1', seq : 1});
いっぱい突っ込む
> for (var i = 2; i <= 100; i++) db.users.insert({ name : 'test' + i, seq : i})
SELECTする
SELECT * FROM users みたいな
> db.users.find();

感想
JavaScriptチックなせいか、なんだかとっても好感触。
これは好きになれそうかも。
