Welcome to the Casbah documentation¶ Welcome to the Casbah Documentation. Casbah is a Scala toolkit for MongoDB—We use the term “toolkit” rather than “driver”, as Casbah integrates a layer on top of the official mongo-java-driver for better integration with Scala. This is as opposed to a native implementation of the MongoDB wire protocol, which the Java driver does exceptionally well. Rather than
DB設計の神ツール「ERMaster」なら、ここまでできる:ユカイ、ツーカイ、カイハツ環境!(11)(1/3 ページ) 無料のEclipseプラグイン「ERMaster」とは データベースのテーブル設計を行うときに皆さんは、どのようにしているでしょうか? いくつかの無料で利用できるツールが提供されているので、筆者はそれらを利用していましたが、最近「ERMaster」と呼ばれるEclipseプラグインの存在を知りました。 ERMasterは、ほかのツールに比べ、直感的で分かりやすいUI(ユーザーインターフェイス)に、カスタマイズ可能な、Excelで出力できるテーブル定義書、辞書機能など痒いところに手が届くERモデリングのツールです。本稿では、このERMasterについてご紹介します。 ERMasterの主な特徴、8つ ERMasterには、主に次のような特徴があります。 【1】直感的で使いや

SQL4GGAE(Google App Engine)上で稼動するSQLデータベース SQL4Gとは? SQL Database for GAEの略称です。 オープンソースのJavaデータベース「H2 Database Engine」をリトルソフトが独自にエンハンスし、GAEが用意しているBigTableと呼ばれる分散キー・バリュー型データストアへ内容を書き込めるようにしたものです。 いまさらRDB? GAEのデータストアはJavaの場合 JDO、JPA といったインターフェースからアクセスすることが出来ますが、JDO、JPAを駆使してGAEのデータストアを自由自在に扱うことは、今までRDBMSに慣れ親しんだ開発者にとっては、少々敷居の高いものになります。 そのため、RDBMSに相当する環境が存在しないGAEは、現状において「クラウドは魅力的だけどデータ周りに難あり」とお考えになる方が多数
Kumofs is a simple and fast distributed key-value store. You can use a memcached client library to set, get, CAS or delete values from/into kumofs.
