AQL tutorial
|
|
============
|
|
|
|
This is an introduction to ArangoDB's query language AQL, built around a small
|
|
dataset of characters from the novel and fantasy drama television series
|
|
Game of Thrones (as of season 1). It includes character traits in two languages,
|
|
some family relations, and last but not least a small set of filming locations,
|
|
which makes for an interesting mix of data to work with.
|
|
|
|
There is no need to import the data before you start. It is provided as part
|
|
of the AQL queries in this tutorial. You can interact with ArangoDB using its
|
|
[web interface](../../Manual/GettingStarted/WebInterface.html) to manage
|
|
collections and execute the queries.

Dataset
|
|
-------
|
|
|
|
### Characters
|
|
|
|
The dataset features 43 characters with their name, surname, age, alive status
|
|
and trait references. The surname and age properties are not always present.
|
|
The column *traits (resolved)* is not part of the actual data used in this
|
|
tutorial, but included for your convenience.
|
|
|
|
|
|
|
|
### Traits
|
|
|
|
There are 18 unique traits. Each trait has a random letter as document key.
|
|
The trait labels come in English and German.
|
|
|
|
|
|
|
|
### Locations
|
|
|
|
This small collection of 8 filming locations comes with two attributes, a
|
|
*name* and a *coordinate*. The coordinates are modeled as number arrays,
|
|
comprised of a latitude and a longitude value each.
