Data Science Fundamentals

The DIKW pyramid is composed of four layers, from base to apex: Data, Information, Knowledge, and Wisdom. Wisdom sits at the apex and represents the highest level of understanding, where accumulated knowledge is applied with judgment and insight to produce meaningful, actionable results and informed decisions. This is distinct from the lower layers: Data becomes Information when context is added (this corresponds to giving raw data meaning), and Information becomes Knowledge when relationships and patterns between data points are established. Wisdom, at the top, goes beyond simply organizing or contextualizing data — it involves synthesizing knowledge to produce meaningful outcomes, judgments, and value, which is why the apex is best described as transforming data (and the knowledge derived from it) into meaningful results.
