# Attributes

**Attributes can relate to an Asset, Order or Material.** TilliT uses a hierarchy to identify what attribute to use, this way you can maintain the same attribute (Max Temperature) in an asset, a material and an order. They can be referenced in Calculations, Read only notes, Active Item Expressions, Hidden Expressions and Tolerances.

Think about the **attributes relevant to your products or orders**.

Data attributes can be of various data types, such as number, text, or booleans (true/false), and can be used to represent different aspects of an configuration.

For example: set points, customers, colours, date of expiration, etc.
