# DDB Asset Hierarchy Structure
Digital Design Brief is designed to support a vast majority of disciplines to access their data and therefore we have built several templates which are to be used when posting or retrieving data for a process.
Map your parameters against the asset tree to enable your process of getting values from different processes which have been executed on your project earlier.
