DATA CONCEPTS (3.1) - COMPREHENSIVE PREPARATION
1. CONCEPTUAL FRAMEWORK: DIKW IN DIGITAL SOCIETY
Extended Definitions with Digital Context
Data in Digital Society: Data represents the fundamental building blocks of the digital world - raw, unprocessed facts, signals, or values lacking context or inherent meaning. In digital environments, this manifests as binary code, unformatted numbers, unstructured text, or raw sensor readings. Data alone carries minimal value until it's processed and contextualized.
Information in Digital Society: When data is processed, organized, structured, or presented within a meaningful context, it transforms into information. Digital platforms constantly perform this transformation, converting raw signals into meaningful indicators. The critical difference is that information answers basic questions (who, what, where, when) that data alone cannot address.
Knowledge in Digital Society: Knowledge emerges when information is interpreted, understood, and applied within frameworks of understanding. Digital systems facilitate knowledge creation by enabling pattern recognition and connection identification across vast datasets. Knowledge answers "how" questions by revealing the methods, processes, and relationships between different information points.
Wisdom in Digital Society: The pinnacle of the hierarchy, wisdom, involves applying knowledge with insight, judgment, and ethical consideration. In digital contexts, wisdom manifests as informed decision-making that considers long-term consequences, ethical implications, and human values. Wisdom addresses "why" questions and guides appropriate actions based on accumulated knowledge.
