Types

A reference to all types in AQL, covering what types are, how they serve as blueprints for objects like models and fields, and the properties each supports.

Type can be understood as the “blueprint”, or the “category” of an object in AQL. Depending on its type, an object can have certain properties.

For example, considering the following model:

Model orders {
  dimension id {type: 'number'}
  dimension total_value {type: 'number'}
  dimension status {type: 'text'}

  measure orders_count {
    type: 'number'
    description: 'Count all orders, regardless of status'
    definition: @aql count(orders.id) ;;
  }
}

orders is an object of type Model
total_value is an object of type Field, with the following properties:
- Field class: Dimension
- Origin model: orders
- Data type: number
orders_count is an object of type Field, with the following properties:
- Field class: Measure
- Origin model: orders
- Data type: number

In this section of the docs, you will find detailed information about different types available in AQL.
