The semantic layer: bringing order to enterprise data chaos

Thankappan, Arun Kumar Palathumpattu (2025) The semantic layer: bringing order to enterprise data chaos. World Journal of Advanced Engineering Technology and Sciences, 15 (1). pp. 211-217. ISSN 2582-8266

This article addresses the growing challenge of data chaos in modern enterprises caused by decentralized data models, fragmented definitions, and inconsistent access controls. Organizations grapple with multiple business intelligence tools and hundreds of data sources, each with unique protocols and models, resulting in inefficiencies and diminished trust in data-driven decisions. The semantic layer emerges as a comprehensive solution, providing a unified abstraction layer between raw data and analytical tools. By standardizing definitions, centralizing access controls, and ensuring consistent metrics across all systems, the semantic layer restores order to enterprise data environments. The article explores the fundamental problems of data fragmentation, outlines the core principles and benefits of semantic layer implementation, discusses technical considerations and challenges, and examines recent technological advancements that enhance semantic layer capabilities, offering organizations a clear pathway to transform chaotic data landscapes into cohesive, reliable information ecosystems.
