We’ll run these commands to import it into our database: arangoimport -server.database movies -file movies.json -collection movieĪrangoimport -server.database movies -file actors.json -collection actorĪrangoimport -server.database movies -file links.json -collection links The movies data is in three JSON files, which you can download from the ArangoDB demo on our SDK site. Now we’ve set up our collections and graph, we can import the data.ĪrangoDB comes with a command-line tool ‘arangoimport’, which makes it easy to import data from different formats. (Note: vertex is a graph database term for node, and an edge is a link). We’ve defined the graph with a single edge collection and 2 collections for vertices. Next, create a graph called ‘movies-graph’ with this setup: two document collections called ‘movie’ and ‘actor’.Then switch to the dashboard for the newly created database and create: So, using the ArangoDB web interface, first create a new database called ‘movies’. In this example, we’ll build a network of movies and actors to explore in a KeyLines application. Go to to see ArangoDB’s neat web interface. See the ArangoDB tutorial on managing users. It’s best to create a user or change the root password before you continue. You can run commands in the shell interface called ‘arangosh’. For this ArangoDB tutorial, we used a Mac and installed the database via Homebrew, so at the command line we enter: There are full instructions in their excellent getting started guide. Step 1: Set up ArangoDBĭownload and install the latest ArangoDB version. ArangoDB combines the advantages of a document, key-value and graph database with good performance and scalability.ĪrangoDB can work with KeyLines to power a robust graph visualization application. One way to avoid these problems is to use multi-model databases like ArangoDB. Deploying to multiple database technologies in a single project is complex and has a greater maintenance overhead. This approach, known as polyglot persistence, ensures good performance but presents challenges. ![]()
