OrientDB Graph Database: Tutorial for the Java API

World-Model for Autonomous Service Robots using the Graph-Database OrientDB

In this tutorial you will learn how to use OrientDB as a Graph Database. You will write Java code and use the Java API to access and control the database. This tutorial covers two alternatives to access the database:

• Navigation using Tinkerpop Blueprints framework
• Declarative access using the SQL dialect of OrientDB

The tutorial is based on a real world application: A service robot should help elderly or disabled persons in their household. To do so it must have knowledge about rooms and objects in its environment. A graph database like OrientDB is ideally suited to store this world model because the database is a highly connected graph.

You will need about three hours for the whole tutorial. You can read all explanations as text but also watch screen-cast videos.
