Microsoft Databases and Microsoft Fabric: Your unified and AI-powered data estate

As AI reshapes every industry, one truth remains constant: data is no longer just an asset—it’s your competitive edge. The pace of AI demands easy data access, faster insights, and the ability to iterate without friction. Yet many organizations are held back by fragmented data estates and legacy systems. Microsoft Fabric was designed to meet this moment—to unify your data, simplify your architecture, and accelerate your path to becoming an AI-led organization. That mission is gaining traction at remarkable speed. Since Fabric launched two years ago, it has grown faster than any other data and analytics platform in the industry. More than 28,000 customers—including 80% of the Fortune 500—now rely on Fabric, and its ecosystem continues to expand as partners build solutions to solve the most complex data challenges.

Another leap forward across Microsoft Databases and Microsoft Fabric

As Fabric becomes the central connection point for data, we’re strengthening the database layer at the heart of your data estate—ensuring you have the scale and performance required for AI. Microsoft already offers one of the industry’s most comprehensive database portfolios, and we’re expanding it even further—while deeply integrating these capabilities into Fabric. I’m excited to announce the general availability of SQL Server 2025, Azure DocumentDB, and SQL database and Cosmos DB in Fabric, along with the preview of our newest addition, Azure HorizonDB. With these new offerings, you have a world-class database option to build once and deploy at the edge, as platform as a service (PaaS), or even as software as a service (SaaS). And because our entire portfolio is either Fabric-connected or Fabric native, Fabric serves as a unified hub for your entire data estate. Below I’ll cover how these new databases are purpose-built to support your AI projects.

All your databases connected into Fabric

We’re making it easier than ever to work with your entire Microsoft database portfolio in Fabric, giving you a single, unified place to manage and use all your data. Building on our existing mirroring support for Azure SQL Database and Azure SQL MI, we’re now announcing the general availability of mirroring for Azure Database for PostgreSQL, Azure Cosmos DB, and SQL Server versions 2016–2022 and 2025. With these databases mirrored directly into Fabric, you can eliminate traditional extract, transform, and load (ETL) pipelines and make your data instantly ready for analytics and AI.

Getting your data estate ready for AI with Microsoft Fabric

Choosing the right database is essential, but it’s just the beginning. The major opportunity lies in driving frontier transformation, where data becomes the foundation for an AI-native enterprise. We recommend focusing on three core steps:

• Unifying your data estate to eliminate silos and complexity.
• Creating semantic meaning so your data is ready for AI.
• Empowering agents to act on insights and transform operations.

In this section, I’ll dive into the latest enhancements to Microsoft Fabric that help you achieve every step of your data journey. This includes expanded interoperability in OneLake with SAP, Salesforce, Azure Databricks, and Snowflake, the introduction of Fabric IQ—a new workload that adds semantic understanding—and enhanced agentic capabilities across Fabric to help you build richer, AI-powered data experiences. This is the future of data, and it’s already within reach. With Fabric and our database innovations, Microsoft is helping organizations move seamlessly from insight to action—unlocking the full potential of your data and the AI built on top of it.

Unify your data estate with Microsoft OneLake

Microsoft OneLake unifies all your data—across clouds, on-premises, and beyond Microsoft—into a single data lake with zero-ETL capabilities like shortcuts and mirroring. Alongside the additional mirroring sources for Microsoft Databases, we’re also introducing the preview of shortcuts to SharePoint and OneDrive. This allows you to bring unstructured productivity data into OneLake without copying files or building ETL pipelines, making it easier to train agents and enrich your structured data. See how shortcuts and mirroring unify your data in OneLake: Once connected to OneLake, your data becomes easily discoverable in the apps your teams use every day like Power BI, Teams, Excel, Copilot Studio, and Microsoft Foundry. Today, we are taking that a step further with native integration with Foundry IQ—the next generation of retrieval-augmented generation (RAG). Agents rely on context—Foundry IQ’s knowledge bases deliver high-value context to agents by simplifying access to multiple data sources and making connections across information. You can use the OneLake knowledge source in Foundry IQ to connect agents to multi-cloud sources like AWS S3, on-premises sources, and structured and unstructured data.

Expanding OneLake interoperability with leading data platforms

We are also seeing great momentum with dozens of partners outside of Microsoft deeply integrating with OneLake, including ClickHouse, Dremio, Confluent, EON, and many more. And now, we are thrilled to add new, deeper interoperability with SAP, Salesforce, Azure Databricks, and Snowflake. First, we’re deepening interoperability with the systems organizations rely on most, SAP and Salesforce. With the launch of SAP Business Data Cloud Connect for Microsoft Fabric, customers can allow bidirectional, zero-copy data sharing between SAP Business Data Cloud (BDC) and Fabric. At the same time, we are working with Salesforce to integrate their data into Fabric using the same zero-copy approach, unlocking advanced analytics and AI capabilities without the overhead of traditional ETL. We’re also strengthening interoperability with Azure Databricks and Snowflake so you can use a single copy of data across platforms. By the end of 2025, Azure Databricks will release, in preview, the ability to natively read data from OneLake through Unity Catalog, enabling seamless access without duplication or complex data movement. Looking ahead, Databricks will also add support for writing to and storing data directly in OneLake, allowing full two-way interoperability. Read more about this interoperability. Our collaboration with Snowflake on bidirectional data access continues as well. We are introducing a new item in OneLake called a Snowflake Database and a new UI in Snowflake—both designed to allow OneLake to be the native storage solution for your Snowflake data. We’re also bringing Snowflake mirroring to general availability, allowing you to virtualize your external Snowflake-managed Iceberg tables in OneLake with shortcuts created and handled automatically. Together, these innovations let you run any Fabric workload—whether analytics, AI, or visualization—directly on your Snowflake-managed Iceberg tables. Learn more about our Snowflake collaboration by reading our latest joint blog or by watching the following demo: Finally, in close collaboration with dbt Labs, we are also excited to announce built-in support for their industry leading data transformation capability. Now in preview, dbt jobs in Microsoft Fabric let you build, test, and orchestrate dbt workflows in your Fabric workspaces. Learn more in this blog.

Create semantic knowledge to fuel AI with Fabric IQ

As Frontier Firms train agents on their enterprise data, it’s become clear that quality and context matter more than data volume. Agents need business context across relationships, hierarchies, and meaning to turn raw data into actionable insight. That’s why we’re introducing Fabric IQ—a new workload designed to map your datasets to the real-world entities they represent, creating a shared semantic structure on top of your data. The power of IQ lies in how it unifies disparate data types under a single, coherent framework. Built upon Power BI’s industry-leading, rich semantic model technology, IQ brings together analytical data, time-series telemetry, and geospatial information, all organized under a semantic framework of business entities and their relationships, properties, rules, and actions. You can then create operations agents, a new type of agent in Fabric, which can use this model to act as virtual team members, monitoring real-time data sources, identifying patterns, and taking proactive action. Instead of forcing your teams and even agents to think in terms of tables and schemas, IQ allows you to align data with how your organization operates. In short, Fabric IQ is designed to model reality with data, so that every insight, prediction, and action is grounded in how your organization actually operates. You can learn more about IQ in Yitzhak Kesselman’s, Corporate Vice President of Messaging and Real-Time Intelligence, announcement blog.

Empower data-rich agents with Copilot, Fabric data agents, and operations agents

As organizations scale their AI initiatives, the ability to connect intelligent agents with enterprise-grade data is becoming a critical differentiator. Fabric is making this possible with a set of integrated AI experiences: Copilot in Power BI helps you ask questions of your data, Fabric data agents allow deeper analysis, and the new Fabric operations agents let you monitor your data estate and take action in real time. These experiences can be used across Fabric or as foundational knowledge sources in industry-leading AI tools like Microsoft Foundry, Copilot Studio or even Microsoft 365 Copilot to power smarter, more data-rich AI experiences. Beyond introducing operations agents as part of Fabric IQ, we’re also expanding what data agents and Copilot can do. Along with existing integration with Microsoft Foundry and Copilot Studio, Fabric data agents can now be embedded directly in Microsoft 365 Copilot. This lets business users (with the right permissions) access trusted knowledge from OneLake and transforms Microsoft 365 from a productivity suite into an intelligent insights platform. They can also act as hosted Model Context Protocol (MCP) servers, making it easy to integrate with other applications and agents across the AI ecosystem. Finally, data agents can now reason across both structured and unstructured data. Thanks to an integration with Azure AI Search, data teams can add their existing unstructured data search endpoints as a source in data agents. Learn more the Fabric data agent enhancements by reading the Fabric AI blog. We’re also enhancing the standalone experience for Copilot in Power BI with a new search experience. Simply describe what you need, and Copilot will locate the relevant report, semantic model, or data agent and surface the right answers. This standalone experience is also coming to Power BI mobile so you can use it on the go. Take a look at how you can apply all of these AI experiences together seamlessly: In short, we’re redefining what it means to have an AI-powered data estate. With data agents, Copilot in Power BI, and operations agents in Fabric IQ, AI is now woven across Fabric. And with native integration to Microsoft Foundry and Copilot Studio, you can easily add Fabric agents as building blocks to create more intelligent, informed custom agents.
