ArangoDB

What is ArangoDB?

ArangoDB is a native multi-model database that combines documents, graphs, and key-value storage in a single database engine. Unlike other databases that bolt on different data models, ArangoDB was built from the ground up to handle multiple data models efficiently with a unified query language (AQL) that can work across all models in a single query.

With features like ACID transactions, horizontal scaling, and SmartGraphs for distributed graph processing, ArangoDB eliminates the need for multiple database systems and the complexity of keeping data synchronized across different databases. It's particularly powerful for applications that need to handle complex relationships alongside traditional document storage.

FOR user IN users
  FILTER user.age >= 25 AND user.age <= 35
  FILTER user.city == "San Francisco"
  SORT user.created_at DESC
  LIMIT 10
  RETURN {
    name: user.name,
    email: user.email,
    age: user.age
  }

FOR vertex, edge, path IN 2..2 OUTBOUND "users/alice" 
  GRAPH "social_network"
  FILTER vertex._id != "users/alice"
  RETURN DISTINCT vertex.name

FOR user IN users
  FILTER user.city == "New York"
  FOR friend IN 1..1 OUTBOUND user GRAPH "friendships"
  FOR order IN orders
    FILTER order.user_id == friend._key
    FILTER order.total > 100
  COLLECT user_name = user.name INTO friend_orders
  RETURN {
    user: user_name,
    high_spending_friends: LENGTH(friend_orders)
  }
