| ArangoDB | |
| ======== | |
| ArangoDB is a scalable open-source multi-model database natively supporting graph, document and search. All supported data models & access patterns can be combined in queries allowing for maximal flexibility. ArangoDB runs on prem, in the cloud – anywhere. | |
| ArangoDB Cloud Service | |
| ------------------------ | |
| Oasis is the simplest way to run ArangoDB. Users can make deployments on all major cloud providers in many regions. Test [ArangoDBs Cloud Service Oasis](https://cloud.arangodb.com/home) for free. | |
| Getting Started | |
| ------------------------ | |
| - [Free Udemy Course](https://www.udemy.com/course/getting-started-with-arangodb) | |
| - [Training Center](https://www.arangodb.com/learn/) | |
| - [Documentation](https://www.arangodb.com/docs/stable/) | |
| For the impatient: | |
| - Start the ArangoDB Docker container | |
| docker run -e ARANGO_ROOT_PASSWORD=test123 -p 8529:8529 -d arangodb/arangodb | |
| - Alternatively, [download](https://www.arangodb.com/download) and install ArangoDB. | |
| Start the server `arangod` if the installer did not do it for you. | |
| - Point your browser to `http://127.0.0.1:8529/` | |
| Key Features in ArangoDB | |
| ------------------------ | |
| - **Multi-Model**: Documents, graphs and key-value pairs — model your data as | |
| you see fit for your application. | |
| - **Joins**: Conveniently join what belongs together for flexible ad-hoc | |
| querying, less data redundancy. | |
| - **Transactions**: Easy application development keeping your data consistent | |
| and safe. No hassle in your client. | |
| Here is an AQL query that makes use of all those features: | |
|  | |
| Joins and transactions are key features for flexible, secure data designs, | |
| widely used in relational databases but lacking in many NoSQL products. However, | |
| there is no need to forgo them in ArangoDB. You decide how and when to use joins | |
| and strong consistency guarantees, without sacrificing performance and scalability. | |
| Furthermore, ArangoDB offers a JavaScript framework called [Foxx](https://www.arangodb.com/community-server/foxx/) | |
| that is executed in the database server with direct access to the data. Build your | |
| own data-centric microservices with a few lines of code. By extending the HTTP API | |
| with user code written in JavaScript, ArangoDB can be turned into a strict | |
| schema-enforcing persistence engine. | |
| Other features of ArangoDB include: | |
| - Use a **data-centric microservices** approach with ArangoDB Foxx and fuse your | |
| application-logic and database together for maximal throughput | |
| - JavaScript for all: **no language zoo**, you can use one language from your | |
| browser to your back-end | |
| - **Flexible data modeling**: model your data as combination of key-value pairs, | |
| documents or graphs - perfect for social relations | |
| - Different **storage engines**: ArangoDB provides a storage engine for mostly | |
| in-memory operations and an alternative storage engine based on RocksDB which | |
| handle datasets that are much bigger than RAM. | |
| - **Powerful query language** (AQL) to retrieve and modify data | |
| - **Transactions**: run queries on multiple documents or collections with | |
| optional transactional consistency and isolation | |
| - **Replication** and **Sharding**: set up the database in a master-slave | |
| configuration or spread bigger datasets across multiple servers | |
| - Configurable **durability**: let the application decide if it needs more | |
| durability or more performance | |
| - **Schema-free schemata** let you combine the space efficiency of MySQL with the | |
| performance power of NoSQL | |
| - **index support**: exploit the perfect index types for your different use cases, including document queries, graph queries, geo location queries, and fulltext searches | |
| - ArangoDB is **multi-threaded** - exploit the power of all your cores | |
| - Easy to use **web interface** and **command-line client tools** for interaction | |
| with the server | |
| - It is **open source** (Apache License 2.0) | |
