Description: A semantic layer is an abstraction layer that allows users to interact with data in a way that makes sense to them, often using business terminology. This layer acts as an intermediary between raw data and end users, facilitating the understanding and use of information. By providing a common language and conceptual framework, the semantic layer helps users navigate complex datasets without needing to understand the underlying technical structure. Key features of a semantic layer include the ability to translate natural language queries into structured database queries, the integration of different data sources, and the normalization of terminologies. This not only enhances data accessibility but also fosters collaboration among different departments within an organization, as everyone can work with a shared understanding of the data. In a Data Mesh environment, where data is treated as products and distributed across domains, the semantic layer becomes crucial to ensure that data is understandable and usable by all stakeholders, regardless of their technical level.
