Data models & modeling

This chapter introduces ArangoDB’s core concepts and covers

• its data model (or data models respectively),
• the terminology used throughout the database system and in this documentation, as well as
• aspects to consider when modeling your data to strike a balance between natural data structures and great performance

You will also find usage examples on how to interact with the database system using arangosh, e.g. how to create and drop databases / collections, or how to save, update, replace and remove documents. You can do all this using the web interface as well and may therefore skip these sections as beginner.
