The document discusses the metastructures of nursing informatics using an analogy to a tree. [1] Data is compared to the nutrients absorbed by the tree's roots. [2] Information is likened to the trunk that guides nutrients throughout the tree. [3] Knowledge represents the leaves, which are produced using nutrients and guided by the trunk. [4] Wisdom is the fruit of the tree, representing the application of knowledge. The goal of these metastructures is wise clinical decision making, just as the fruit nourishes those who eat it.
