Estimated reading time: 7 minutes

At ArangoDB, our commitment to empowering companies, developers, and data enthusiasts
with cutting-edge tools and resources remains unwavering. Today, we’re thrilled to unveil our
latest innovation, the Data Loader, a game-changing feature designed to simplify and streamline
the migration of relational databases to ArangoGraph. Let’s dive into what makes Data Loader a
must-have tool for your data migration needs.

Say Goodbye to Complex Relational Database Structures

If you’ve ever grappled with the intricate relationships of old-school relational databases, where
tables connect to other tables, and a third table acts as the linchpin, you understand the
challenge of managing data in this convoluted setup. It’s like solving a puzzle – finding
connections, managing dependencies, and ensuring data integrity, a time-consuming process
prone to errors.

Data Loader is your go-to solution for effortlessly migrating relational databases to
ArangoGraph. This powerful tool simplifies the process by allowing you to define edge relations
between nodes with a simple drag-and-drop of raw CSV files. Whether you’re a seasoned
developer or just starting your journey with ArangoDB, Data Loader provides an intuitive and
user-friendly interface, making the migration process a breeze.

You could go from the old-school, less intuitive approach like this:

Say goodbye to the days of dealing with convoluted relational structures. Data Loader welcomes
you to a new era of data management simplicity. It’s not just a tool; it’s a revolution in how you
approach and manage your data relationships.

The Significance of Data Loader

The true significance of Data Loader lies in its ability to transform your existing relational tables
into a graph full of relationships. By leveraging this tool, you can harness the power of
ArangoGraph without the complexities of manual data migration. It’s a bridge that effortlessly
connects your relational data to the world of graph databases.

Our Clear Goal: Making Data Migration Comfortable and Intuitive

Our goal with Data Loader is crystal clear – to make migrating to a graph-type model
comfortable and intuitive. Whether your use case is simple or complex, Data Loader empowers
you to transition from relational databases to ArangoGraph, unlocking the full potential of
graph-based data modeling.

The Future of Data Loader

As we continue to evolve, Data Loader is just the beginning. We’re excited to announce that, in
the future, we’ll be expanding its capabilities to support additional file formats, including TSV
and JSON files. This ensures that Data Loader remains a versatile and comprehensive solution
for all your data migration needs.

Welcome to a new era of seamless data migration with ArangoDB.

Now, let’s delve into a hands-on tutorial to guide you through the process. This tutorial leverages
a sample dataset of two files: ‘airports.csv’ and ‘flights.csv.’ These files will allow us to craft a
graph that showcases flights arriving and departing from diverse cities worldwide.

Let’s break down the process into easily manageable steps:

  1. Database and Graph Setup: Begin by naming your database and graph you would like
    to use for the data import.
  2. Upload files: Use the intuitive Data Loader web interface and simply drag & drop your
    CSV files or upload them through the file browser window.
  3. Design graph: Add nodes and edges and map data from the uploaded files to them.
    This will allow you to create your graph’s corresponding documents and collections.
  4. Import data: Finally, import the data and start using your newly created graph and

Let’s start by creating a new database and adding a name for our graph.

Now, let’s upload the files. You can drag and drop or upload them via a file browser window.

Once the files are in, we can design a graph schema. This tutorial will be a simple graph
consisting of two nodes (“origin_airport” and “destination_airport”) and a directed edge going
from the origin airport to the destination one representing a flight. Click Add node to create
nodes and connect them with edges.

Next, for each of the nodes and edges, we create a mapping to the corresponding file and

For nodes, the node label will be a node collection name, and the primary identifier will be used
to populate the _key attribute of documents. We can also select any additional headers to be
included as document attributes. In this example, we’re creating two node collections,
“origin_airport” and “destination_airport.” The “AirportID” header will be used to create the _key
attribute for documents in both node collections. The header preview makes it easy to select the
headers you want to use.

For edges, the edge label is going to be an edge collection name. Then, we need to specify how
edges will connect nodes. We do this by selecting the from and to nodes to give a direction to
the edge. In this example, we select the “source airport” header as a source and the
“destination airport” as a target for the edge.

Note that the values of source and target for the edge correspond to the primary identifier (_key
attribute) of the nodes. In this example, the airport code (i.e., GKA) is used as the _key in the
node documents and in the source and destination headers to configure the edges.

After all the mapping is done, all we need to do is click Save and start import. The report
provides an overview of the files processed and documents created and a link to your new

Finally, click See your new graph to open the ArangoDB web interface and explore your new
collections and your new graph. Happy graphing!
