Database-as-a-Service for MongoDB

MongoDB is a general purpose, document-based, distributed data platform built for modern application developers and for the cloud. No data platform is more productive to use.

The MongoDB data platform is built around three core design principles that collectively enable you to build faster, and with higher quality: 1. The document data model – presenting you the best way to work with data. 2. A distributed systems design – allowing you to intelligently put data where you want it. 3. A unified experience that gives you the freedom to run anywhere – allowing you to future-proof your apps and eliminate vendor lock-in.

最も手軽なのは、MongoDB Universityの開発者およびDBA向け無料オンライン講座です。講座はMongoDB, Inc.のエンジニアが作成し、指導しています。196か国から100万件を超える登録があり、受講者はMongoDB上でのアプリケーション開発と展開を学んでいます。

MongoDB University free courses cover everything you need to know to become a MongoDB expert. Online training courses are developed specifically to help you build new skills in the areas that matter most to employers. The online training courses are based on real-world applications and taught by our dedicated team of in-house engineers who work on the code every day and have seen use cases across 13,000+ companies.

MongoDB University training courses are self-paced, allowing you to review the videos and course materials at a time that is convenient for you. At the same time, we offer structure to your learning with weekly assignments and deadlines to check in on your progress and a final exam to test your knowledge. Most courses run for three weeks, and each week typically requires just 90 minutes of your time. Find a course that’s right for you. View the course catalog.

Data in MongoDB is stored in BSON documents – JSON-style data structures. Documents contain one or more fields, and each field contains a value of a specific data type, including arrays, binary data and sub-documents. Documents that tend to share a similar structure are organized as collections.

ドキュメントはリレーショナルデータベースの行、フィールドは列、コレクションは表にあたると考えると理解しやすいかもしれません。

開発の効率を高めるため、MongoDBは主要なプログラミング言語とフレームワーク向けに専用ドライバを提供しています。Java、JavaScript、C#/.NET、Go、Python、Perl、PHP、Scalaなどに対応します。いずれも各言語の作法に沿って設計されているため、SQLのような文字列ベースの言語よりも自然にデータを扱え、扱いにくく壊れやすいORMの抽象層も不要になります。

MongoDB用のGUIであるMongoDB Compassを使えば、画面上で操作することもできます。Compassではデータの閲覧と編集、クエリや集計処理の視覚的な作成とコードとしての書き出し、クエリの実行状況と性能の確認、索引の表示と作成、スキーマ検証ルールやビューの作成などが行えます。

対応しています。複数文書にまたがるACIDトランザクションは、2018年のMongoDB 4.0以降ご利用いただけます。
