OneLake for One Truth: Microsoft Fabric’s Potential for Enterprise Data Warehousing

by | Jul 8, 2023 | Articles

Data is often scattered across different platforms and managed by multiple vendors. This leads to disjointed, cumbersome, and costly data architecture. However, with the introduction of Microsoft Fabric’s OneLake, the world of data warehousing and data management is going to have a significant shift.

At Centida, we see Fabric as a game-changer that will bring a new era of enterprise data warehousing (EDW). The new platform will address a range of comprehensive organizational analytics needs with unparalleled efficiency.

Challenges of data warehousing

Traditional data warehousing solutions are increasingly insufficient in the face of growing data volumes, heightened complexity, and rising costs. Challenges, such as data duplication, vendor lock-in, and governance issues have become stumbling blocks in the world where data is the lifeblood of business.

Enterprises generate vast quantities of data through devices, applications, and various other tools. Harnessing this data is critical to driving transformation and gaining a competitive edge. However, existing tools are often specialized and disconnected services, posing considerable challenges to data integration and management.

Microsoft Fabric introduces a new approach, known as the OneLake concept, that will streamline and unify data management. We at Centida have come to describe this transformation with the phrase “OneLake for One Truth”. This neatly describes the revolutionary shift towards a unified data ecosystem in the EDW industry.

Tapestry of data management with Microsoft Fabric

Launched on May 23, 2023, Microsoft Fabric is an end-to-end, cloud-based SaaS solution for data and analytics. With the solid foundation of an open lakehouse, known as OneLake, Fabric seamlessly integrates various Microsoft tools to create a streamlined workflow for data integration, engineering, real-time analytics, and data science. It unlocks data’s potential and lays the groundwork for the emerging era of AI.

In the context of the EDW landscape, Fabric distinguishes itself with the following unique features and advantages:

    • Unified Analytics Infrastructure. Fabric operates as a unified platform that diminishes the complexities inherent in dealing with a multitude of vendors, thus streamlining the analytics process.
    • Centralized and Open Data Lake. Fabric’s core is OneLake, a built-in multi-cloud data lake. This simplifies data management and, in tandem with Fabric’s dedication to open data formats, effectively bypasses the dilemma of vendor lock-in.
    • Integration of AI Capabilities. With the infusion of Azure OpenAI Service, Fabric brings AI within reach for both developers and business users, making it an AI-forward solution.
    • Enhancing User Engagement. By incorporating Microsoft 365 applications into its framework, Fabric allows business users to discover and apply data insights directly within their work environment, thereby improving productivity and user experience.
    • Cost-Efficient Solution. Fabric capitalizes on a unified computing resource pool across all workloads, which leads to significant cost savings and operational efficiencies.

OneLake for One Truth

At the core of Microsoft Fabric, OneLake acts as the unified storage account for all data used within Fabric. OneLake simplifies data management and encourages distributed ownership of organizational data. Its open access nature, a shortcuts feature to reduce data duplication, adherence to the “One Copy” principle, and a robust security model all work towards providing a seamless data management experience.

As Geoffrey Freeman from T-Mobile says, “Querying across the lakehouse and warehouse from a single engine—that’s a game changer.”

Given this, OneLake’s structure presents a single storage account to the end user while acting like a logical suite of Azure storage accounts. This simplified management of data, coupled with its easy accessibility through various tools like Fabric UI, Azure Storage Explorer, and OneLake File Explorer, marks a significant departure from traditional data storage solutions, such as ADLS Gen2.

With OneLake, data duplication becomes a thing of the past, and data governance is simplified.

The Lakehouse Paradigm

The lakehouse in Microsoft Fabric is a versatile data architecture platform that combines the best of data lakes and data warehouses. It allows organizations to manage and analyze structured and unstructured data, all in a single location. It integrates with a variety of tools and frameworks, enabling organizations to handle large data volumes efficiently and seamlessly. Importantly, only the tables in Delta format are available in the SQL Endpoint, reflecting the lakehouse’s emphasis on robust data handling capabilities.

The introduction of Microsoft Fabric represents a fundamental shift in how enterprises will manage and analyze their data. This new platform empowers organizations to harness the power of their data more effectively and cost-efficiently, unlocking the potential for greater business insights and innovation. As Fabric continues to evolve and mature, its influence on the data landscape is likely to grow, redefining the rules of the game for EDW.


The introduction of Microsoft Fabric and its OneLake concept marks a fundamental shift in EDW. By addressing issues, such as data duplication, vendor lock-in, and fragmented data ownership, Fabric empowers organizations to truly harness the power of their data. The convergence of data into a single, robust lakehouse not only reduces costs but also fosters an open, AI-powered data ecosystem.

The “OneLake for One Truth” paradigm promises a future where data management is more efficient, cost-effective, and seamlessly integrated into the fabric of the organization.
