****** ArangoDB ******
|
|
|
|
ArangoDB is a multi-model, open-source database with flexible data models for
|
|
documents, graphs, and key-values. Build high performance applications using a
|
|
convenient SQL-like query language or JavaScript extensions. Use ACID
|
|
transactions if you require them. Scale horizontally with a few mouse clicks.
|
|
The supported data models can be mixed in queries and allow ArangoDB to be the
|
|
aggregation point for your data.
|
|
To get started, try one of our 10 minutes tutorials in your favorite
|
|
programming language or try one of our ArangoDB_Cookbook_recipes.
|
|
For the impatient: download and install ArangoDB. Start the server arangod and
|
|
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 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:
|
|
Microservice Example
|
|
[Microservice Example]
|
|
By extending the HTTP API with user code written in JavaScript, ArangoDB can be
|
|
turned into a strict schema-enforcing persistence engine.
|
|
Next step, bundle your Foxx application as a docker_container and get it
|
|
running in the cloud.
|
|
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
|
|
* Free index choice: use the correct index for your problem, be it a
|
|
skiplist or a fulltext search
|
|
* ArangoDB is multi-threaded - exploit the power of all your cores
|
|
* It is open source (Apache License 2.0)
