What is the process of organizing information into different tiers or categories called?

The process of organizing information into different tiers or categories is known as data classification. This practice involves categorizing data based on certain criteria or characteristics, which can help in managing, securing, and retrieving the information more effectively. Data classification can be essential for various reasons, including compliance with privacy regulations, optimizing storage solutions, and enhancing data governance strategies.

In contrast, data aggregation refers to the process of collecting and summarizing data from multiple sources, and is more focused on the compilation of data rather than its organization into tiers. Information hierarchy is a related concept, but it more specifically describes the way information is structured in a system, often emphasizing the relationships and levels of importance among data elements. Data segmentation, on the other hand, typically refers to dividing data into segments, often for purposes like analysis or targeting in marketing, and does not encompass the broader process of categorization that data classification entails.
