Slightly updated version of the Medium story
Introduction
The semantic layer is increasingly becoming a key factor in modern data management. The lack of such a layer poses significant challenges, ranging from limited data availability, inconsistencies in reporting and poor decision making to increased strain on IT resources. The struggle to democratize data is intensified by the proliferation of disparate BI tools and data sources, often leading to inconsistent analytical results and governance issues.
The introduction of a semantic layer helps to solve these challenges by serving as a consistent representation of business data. By translating complicated data structures into familiar business terms, a unified view of data is created across the organization, simplifying access and ensuring consistency. Professionals emphasize the importance of bridging the gap between data engineering and business analytics.
This article defines semantic layers, highlighting their role in organizing enterprise data and aiding decision-making. It details benefits like improved data consistency, governance, and agility, making semantic layers crucial for efficient, informed AI and data management.
Why Do We Need a Semantic Layer?
Micah Horner (TimeXtender) puts it in a nutshell. He argues, that without a semantic layer, organizations face challenges that hinder the effective use of data:
Kieran O’Driscoll (AtScale), Kyle Hale and Soham Bhatt (Databricks) explain in their blog article, that most enterprises are still struggling with data democratization.
Making data available to decision-makers is challenging, especially for large organizations. Over half of enterprises use three or more BI tools, with data scientists and application developers having their own preferences.
Different tools and query languages create conflicting analytics outputs. Multiple business units using different data copies or OLAP solutions like Tableau Hyper Extracts, Power BI Premium Imports, or SSAS intensify this issue.
Storing data in various marts, warehouses, and reporting tools prevents a single version of truth. This increases data movement, ETL, security, and complexity, creating a data governance nightmare and relying on potentially stale data.
AtScale uses an example to illustrate very clearly why companies need a semantic layer:
A marketing team, for example, may refer to a business as a “prospect” by managing the leads in Salesforce. The sales team might call that same business a “client” as orders and deliveries are managed in SAP ERP, and the finance team calls the same business entity a “counter party” as the invoicing process is managed in Oracle EBS. In this complex environment, how do you get a report that aligns all three data elements to one? In the current siloed data landscape, it is not possible to get a single “Lead to Cash” report due to different data definitions originating from multiple source systems. The solution lies in having one standard and consistent definition for this business entity where “prospect,” “client,” and “counterpart” are mapped to one data entity. With the semantic layer, different data definitions from different sources can be quickly mapped for a unified and single view of data. [AtScale: What is a Semantic Layer?]
Donald Farmer (AtScale) highlights the profound challenges between data engineers and business analysts and explains why semantic layers are helpful in bridging this gap.
Many organizations struggle with data-driven decisions due to a disconnect between data engineers, who prefer code-based environments, and business analysts, who lean towards non-code interfaces. This misalignment causes inefficiencies, inconsistent data definitions, and poor decision-making. A robust semantic layer can bridge this gap by offering APIs for engineers and intuitive interfaces for analysts, optimizing organizational skills and techniques.
Semantic layers provide a unified platform accommodating diverse working styles, enhancing collaboration, data governance, and innovation. They offer robust APIs for engineers to programmatically access and manipulate data, integrating seamlessly into workflows. Simultaneously, they provide intuitive interfaces for analysts to explore and visualize data without extensive technical expertise. This unified foundation ensures consistent definitions and metrics, fostering better communication and alignment. Features like shared workspaces, version control, and annotation capabilities promote collaboration and knowledge sharing, enabling organizations to harness data effectively and drive business value.
What is a Semantic Layer
Wikipedia defines the semantic layer as follows:
A semantic layer is a business representation of corporate data that helps end users access data autonomously using common business terms managed through Business semantics management. A semantic layer maps complex data into familiar business terms such as product, customer, or revenue to offer a unified, consolidated view of data across the organization.
By using common business terms, rather than data language, to access, manipulate, and organize information, a semantic layer simplifies the complexity of business data. Business terms are stored as objects in a semantic layer, which are accessed through business views.
The semantic layer enables business users to have a common “look and feel” when accessing and analyzing data stored in relational databases and OLAP cubes.
AtScale gives following definition for a semantic layer:
A semantic layer is a business representation of data and offers a unified and consolidated view of data across an organization. With a semantic layer, different data definitions from different data sources can be quickly mapped for a unified, consistent, and single view of data for analytics and other business purposes. [What is a Semantic Layer?]
and further explanation …
A semantic layer maps business data into familiar business terms to offer a unified, consolidated view of data across the organization and meet the growing analytics needs of an enterprise. …The semantic layer is a metadata and abstraction layer built on the source data (eg.. data warehouse, data lake, or data mart). The metadata is defined so that the data model gets enriched and becomes simple enough for the business user to understand. [What is a Semantic Layer?]
Lulit Tesfaye (Enterprise Knowledge) defines the Semantic Layer as follows:
A semantic layer is a standardized framework that organizes and abstracts organizational data (structured, unstructured, semi-structured) and serves as a data connector for data and knowledge. Larger than a data fabric, that is more focused on structured data, a semantic layer connects all organizational knowledge assets including content items, files, videos, media, etc. via a well defined and standardized semantic framework. It allows organizations to represent organizational knowledge and domain meaning to systems and applications, defining the relationship between content and data. [What is a Semantic Layer? (Components and Enterprise Applications)]
and further …
… a semantic layer that incorporates content makes it possible to organize and enrich content with semantic meaning, empowering consuming systems and end users with advanced content management, discovery, and analytical capabilities. [Adding Context to Content in the Semantic Layer]
Summarizing these definitions, the semantic layer can be defined as follows:
A semantic layer translates complex enterprise data into familiar business terms and provides a unified view by mapping different data sources and managing data relationships. It simplifies data models for users and includes structured, unstructured and semi-structured data. By acting as a metadata layer, it improves the management and analysis of content. It serves as an abstraction layer between databases and end users, provides consistent data views and facilitates intuitive queries without SQL knowledge. It also supports data management through access controls, data quality assurance and policy enforcement.
How The Semantic Layer Supports Business Needs
A semantic layer offers a unified view of data, enabling consistent access and queries. It enhances user experience, organizational efficiency, and provides a standardized approach for enterprise-wide analytics, resulting in numerous benefits:
Implementing a Semantic Layer
Businesses require a tool capable of abstracting data from various sources, contextualizing it, and extracting actionable insights consistently, enabling data literacy for all users. A modern “universal” semantic layer platform enhances the original strengths of the semantic layer by centralizing governance and promoting a business-oriented view of data.
Building Blocks of Semantic Layers
Micah Horner (TimeXtender) explains the building blocks of a semantic layers that seamlessly translate complex data structures into intuitive user experiences:
1. Data ingestion
2. Data Preparation
3. Data Delivery
David P. Mariani (AtScale), argues for the implementing of a universal semantic layer that leverages transformation services in the metrics layer of the A16Z data stack, data modeling, workflow management, and permissions and security. This layer offers significant benefits when properly coordinated, such as:
Success depends on taking advantage of a centrally managed semantic layer that allows users to innovate freely without semantic sprawl.
The Metrics Layer: The metrics layer serves as the single source of truth for enterprise metrics, accessible by various analytics tools. It provides a metrics store for BI tools, applications, reverse ETL, and data science tools, with design and change management integral to its function. Effective metrics layers require curation, change management, discoverability, and serving capabilities for consistency, efficiency and a seamless user experience.
Data Modeling: Data modeling involves creating logical data concepts mapped to physical structures in a warehouse or lakehouse. It can use visual frameworks or code-based languages. Key activities include making data “analytics-ready,” defining conformed dimensions, and designing metrics. This embeds business semantics into the data model, promoting consistency, governance, and innovation through a composable analytics approach.
Workflow Management: Workflow management orchestrates physical transformations for the semantic layer, optimizing cost and performance. Users demand minimal query latency, requiring data aggregate materialization due to cloud-scale data. Performance management automates materializations, adapting dynamically while considering cloud and labor costs. Leveraging semantic layer data, workflow management optimizes performance and costs.
Entitlements and Security: Entitlements and security in the semantic layer enforce data governance policies dynamically at query time, ensuring users access the correct data. Managing various entitlements and consistent definitions maintains trust and integrity. Performance optimization considers user entitlements and use case priorities. Real-time policy enforcement is crucial, while broader security services extend beyond the semantic layer.
Integrating the Semantic Layer within the Modern Data Stack
David P. Mariani also points out that the layers of the modern data stack must be seamlessly integrated with the surrounding layers.
The semantic layer requires deep integration with the neighboring data layers, including the data platform, analytics and output layer, as well as the metadata and services layer.
A universal semantic layer on a cloud data platform centralizes data in a warehouse or lakehouse. Hybrid/multi-cloud setups need data virtualization for cross-platform queries. Effective workflow management requires tight integration with various data platform architectures:
Query Engine Orchestration: Dynamically translates queries from consumers to platform-specific SQL, optimizing for platform idiosyncrasies and reflecting logical-to-physical mapping in the semantic model.
Transformation Orchestration: Manages materialization of views into physical tables, optimizing for performance and cost within the data platform.
Writeback Orchestration: Handles creation of new data or metadata within the data platform, based on user or AI/ML interaction.
User Defined Function (UDF): Utilizes libraries of functions in cloud data platforms for analysis and output, enhancing semantic layer capabilities.
Metadata & Support Services: The semantic layer collaborates with various tools in the data fabric ecosystem by supporting integrations with metadata and support services:
Building a Semantic Lakehouse With AtScale and Databricks
The collaboration between AtScale and Databricks aims to create a Semantic Lakehouse, offering an abstraction layer on physical tables. This simplifies data consumption by defining entities, attributes, and joins, providing a business-friendly view for analysts and end users.
The AtScale semantic layer sits between analytics tools and the Databricks Lakehouse, abstracting data to make it easily consumable. It connects via Hive SQL, SSAS cube, or web service, pushing queries to Databricks for optimized SQL execution, ensuring performance and scalability.
AtScale’s Universal Semantic Layer uses autonomous performance optimization to identify query patterns and automatically manage aggregates. This eliminates manual effort, creating “Diamond Layer” aggregates in Delta Lake, enhancing BI report performance and simplifying analytics data pipelines and engineering.

AtScale’s Universal Semantic Layer unifies BI and AI/ML teams, providing consistent access to enterprise data. It ensures business users in Excel and data scientists using Notebooks can leverage Databricks Lakehouse’s full power.
Semantic Layer in Data Analysis
The flexibility of data analysis is paramount for organizations that want to remain agile and make informed decisions quickly. A semantic layer plays a central role in enabling this flexibility by abstracting the data layer from the visualization layer. Thanks to this abstraction, analysts can easily create different views of the data, including charts, tables and graphs, and easily change analyzed fields and metrics. As a result, analysts can quickly gain new insights and enable companies to adapt their strategies to changing market conditions in a timely manner.
Richard Makara (Reconfigured) points out that companies with a semantic layer become more flexible in their decision-making as they can access updated data as soon as it becomes available. This real-time data access enables proactive responses to changes in the business environment and facilitates the identification of new opportunities and potential risks. Leveraging this flexibility can be critical for organizations seeking competitive advantage and informed decision-making in today’s fast-paced business environment. It enables users to:

The implementation of a semantic layer offers substantial benefits to data governance. By providing a unified view of data, streamlining management processes, and enhancing data quality and security, it becomes an indispensable tool for effective data management and informed decision-making.
Empowering AI with a Semantic Layer
David P. Mariani (AtScale) points out, that leading data organizations prioritize augmented analytics with AI, integrating diagnostic, predictive, and prescriptive analytics, enhancing efficiency by integrating Data Science/Machine Learning platforms, reducing data movement.
Publishing Model-generated Insights: Production AI/ML models generate new data points (e.g. predictions, features) that need to be exposed to users in order to create value. A semantic layer can leverage existing analytics and output infrastructure to more easily disseminate augmented analytics.
Explainable AI / Trusted AI: The semantic layer can be leveraged to organize and disseminate information related to why an AI model is providing a particular answer. For instance, business users can gain value from knowing not only the prediction for sales next quarter, but also the key drivers for this prediction. Delivering better insight on the reasoning behind AI/ML model suggestions directly support explainability and enhance the level of trust in model-generated insights.
Imran Chaudhri (Progress) points out, that integrating Generative AI with enterprise data enhances reliability, transparency, and security while improving data quality and scalability. By leveraging semantic layers, enterprises reduce errors, ensure trustworthiness, and comply with governance standards, unlocking innovative cost-saving opportunities and paving the way for enhanced decision-making and operational efficiency. Two key benefits of semantic layers:
Reduced Hallucinations in the Generative AI’s Outputs: Generative AI models often produce incorrect answers, known as hallucinations, due to their lack of human reasoning and understanding. These errors, occurring 15–20% of the time, can be reduced by using semantic data platforms to contextualize and harmonize data. Proper data cleaning, curating, and modeling are essential for improving AI accuracy.
Improved Reliability and Trustworthiness of the Generative AI’s Outputs: Generative AI models often produce irrelevant, inaccurate, or biased outputs, which can be problematic for critical business decisions. By integrating generative AI with enterprise semantic data systems, companies can enhance the accuracy and trustworthiness of AI outputs. Using private, semantically tagged data, generative AI gains deeper insights into an organization’s unique context. This integration ensures the AI system accesses real-time, updated data, addressing the “training data cut-off” issue and improving the overall quality of generated answers.
Cube emphasizes, that the semantic layer provides crucial context for large language models (LLMs) in AI-powered data experiences. By organizing data into meaningful business definitions and providing a query interface, it ensures LLMs understand data contextually, reducing errors and hallucinations while enabling innovative AI applications and simplifying querying processes.
LLMs, while revolutionary, encounter limitations, particularly in producing accurate outputs due to the “garbage in, garbage out” issue — LLMs hallucinate. Simply feeding them database schemas isn’t sufficient for generating correct SQL. They require a semantic layer to comprehend data contextually, including metrics, dimensions, and relationships. This layer organizes data into business definitions for querying, ensuring accuracy by enforcing LLMs to query through it. Thus, the semantic layer addresses the problem of LLM hallucination by providing necessary context and ensuring the correctness of queries and data outputs.
Combining LLMs with semantic layers unlocks new AI-driven data experiences. These layers provide essential context for AI agents, enabling accurate data querying and empowering organizations to build custom LLM applications. Positioned atop data warehouses, semantic layers facilitate seamless integration with AI technologies.
The semantic layer data model provides structure and definitions used as a context for LLMs to understand data and generate correct queries. By abstracting complex joins and calculations, The semantic layer provides a simplified interface based on business-level terminology, reducing errors and preventing hallucinations.
Artyom Keydunov (Cube) underlines that a universal semantic layer streamlines data consumption across various BI tools, eliminating re-work and fostering trust with a consistent data source. It defines metrics and metadata for all data experiences, ensuring data is accessible across diverse platforms, from BI software to AI tools. This versatility accommodates the evolving landscape of data delivery and supports next-gen data-driven applications.
No AI without consistent data: High-quality data is essential for AI, enabling reliable insights from vast datasets. The universal semantic layer becomes pivotal in this context, providing AI tools with business context and definitions to prevent errors. AI can enhance the semantic layer by suggesting improvements to definitions and code, facilitating data curation and democratization through natural language queries for business users.
The rise of applied AI: The proliferation of AI extends not only to large platforms but also to domain-specific applications, necessitating a universal semantic layer for consistent, accurate data. The semantic layer ensures that inputs are accurate, relevant and consistent. This is critical for accurate results and competitive advantage in AI-driven experiences.
The benefits of an AI-ready universal semantic layer: An AI-ready universal semantic layer is essential for connecting diverse data platforms, facilitating data democratization and powering customer-facing applications.
For example, an AI-ready universal semantic layer can inform business users in real time and in context. Imagine that you are a sales operations professional who spends all day in an application like Salesforce. There is no time to learn a BI tool or jump out of Salesforce to do deeper analysis across sales, support, and purchasing data. Instead, a universal semantic layer makes it possible to embed AI-assisted analytics into a tool like Salesforce, allowing for the analysis to be done within the domain-specific business context — and via a near real-time process that can be as easy as querying an AI chatbot. [Real-time AI Experiences Can’t Advance Without a Universal Semantic Layer]
Patrik Liu Tran (Validio) emphasises that the semantic layer is attracting a lot of attention from companies that want to create innovative data experiences with AI and LLMs. An important goal is to enable natural language queries to LLMs to streamline data retrieval and free analysts from trivial tasks.
Integrating LLMs with semantic layers drastically improves accuracy, up to 300%, by pre-defining metrics and reducing the risk of erroneous assumptions. With semantic layers, LLMs adhere to agreed-upon business metrics, enhancing precision. As LLMs become more prevalent, the importance of semantic layers for data-driven organizations is becoming clearer. They promise more efficient and accurate data processing and analysis, which in turn enables better decision-making and operational efficiency.
