ECE Group's Transformation: Embracing Microsoft Fabric for Data Management Success

ECE Group, one of Europe’s retail pioneers, has made a decisive leap into the future of data management by embracing Microsoft Fabric. The transformation illustrates how a family-owned company—founded in 1965 by Werner Otto, the visionary behind Germany’s shopping center revolution—can overcome aging infrastructure to deliver faster, more reliable insights across multiple markets and asset classes.

A Data-Driven Retail Giant Faces Modern Challenges​

ECE Group manages about 200 shopping centers in 12 countries and plays a pivotal role in developing not only retail properties but entire urban districts. With 20,000 tenant partners and a constant stream of sales, contracts, and operational data, the scale of their daily information processing is staggering. The company handles around two terabytes of uncompressed data every day, collected from over 40 different source systems.
Despite having an on-premises data warehouse in place for more than 15 years, the rapid influx of data began to expose the limitations of their legacy systems. Routine queries—ranging from determining the number of vacant retail spaces to tracking maintenance schedules—used to take three to four hours. Over time, as data complexity grew, it started consuming more than eight hours, hampering quick decision-making and increasing operational costs.

The Shift from Legacy Infrastructure to the Cloud​

Confronted with the challenges posed by an outdated infrastructure, ECE Group reached a pivotal moment. The pressing question was: Should they invest heavily in new hardware, or should they transition to a more flexible, cloud-based model? The answer came in the form of Microsoft Fabric, a robust, integrated platform specifically designed for modern data warehousing.
Key factors influencing their decision included:

• Performance and Scalability: Microsoft Fabric’s cloud-native architecture ensures rapid data loading and efficient processing—even as datasets grow.
• Cost Efficiency: The pay-as-you-use cost model means that ECE Group now spends only for the resources they consume, eliminating waste and enabling predictable budgeting.
• Integration and Future-Proofing: Having already leveraged various Microsoft services, the promise of seamless integration with tools like Power BI and advanced cloud solutions was irresistible.
• Enhanced Focus on Content: With infrastructure management off their plates, ECE’s IT team can now concentrate on delivering actionable insights and exploring emerging technologies such as artificial intelligence.

Jan Hambach, Team Leader IT Analytics at ECE Group Services GmbH & Co. KG, encapsulated this sentiment by noting that the move to a SaaS-based solution allowed them to “concentrate on content.” With this transition, the company effectively shifted from a time-consuming manual data evaluation process to an agile, cloud-enabled environment.

A Methodical, Step-by-Step Migration​

Instead of opting for a high-risk “big bang” migration, ECE Group and its partners decided on a staggered approach. This method allowed the team to learn from each phase and adjust subsequent migrations for optimal performance.
The migration plan unfolded across five distinct data blocks:

1. Center Management Data – Vital for daily operational decisions.
2. Company Data – Encompassing internal metrics and performance indicators.
3. Sales Data – A critical driver of retail analytics.
4. Process Data – Underpinning the smooth functioning of business processes.
5. Investment Data – Already fully migrated to the cloud, the success of this block bolstered confidence in the overall strategy.

With the investment data already enjoying the benefits of the new system, the plan is to move two additional data blocks by spring 2025 and complete the migration with the final two blocks by summer 2025. This incremental strategy not only minimizes disruptions but also provides immediate benefits to users who can now access their content directly from the cloud.
Heiko Gronwald, Head of Data Platform Solutions at adesso SE, emphasized the importance of a gradual migration: “Our aim was to enable users to benefit from the new solution as quickly as possible.” By breaking down the migration into manageable steps, ECE ensured that lessons learned could be applied to further phases, ultimately reducing risk and increasing efficiency across the board.

Unleashing AI and Enhanced Analytics Capabilities​

The transition to Microsoft Fabric isn’t just a backend overhaul—it paves the way for advanced technologies and strategic insights that are essential for staying competitive. With the integration of artificial intelligence, ECE Group gains the ability to automate complex analytics processes and derive insights from data that were previously hidden in the noise.
Imagine a scenario where AI-powered analytics predict shifts in consumer behavior, flagging potential vacancies or identifying optimal times for promotions. This forward-thinking approach empowers property managers and investors alike, enabling them to make decisions based on real-time data rather than waiting for periodic, manual compilations.
The benefits of this integration include:

• Accelerated Data Processing: AI algorithms, combined with the scalable architecture of Microsoft Fabric, compress processing times dramatically.
• Improved Accuracy: Automated data analysis minimizes human error, ensuring that decisions are based on reliable datasets.
• Deeper Insights: With advanced analytics at their fingertips, stakeholders can uncover trends and patterns that were previously impossible to detect using traditional methods.

In short, the integration of AI not only boosts efficiency but also transforms data into actionable insights. It’s a combination that could soon become the standard in data-driven real estate management—and it’s a change that resonates well within the wider IT community.
