Mendix data hub integration: Streamlining multi-app ecosystems

As enterprises adopt more applications to support their teams, partners, and customers, managing consistent, real-time data flow across these systems becomes increasingly complex.

This rise in application usage is driven by the need for greater agility, faster innovation, and more personalized customer experiences. Low-code platforms like Mendix accelerate development, but they also introduce integration challenges—especially when data is scattered across silos and legacy systems.

The challenge of fragmented data ecosystems

As organizations scale their digital presence, the number of applications in use often grows just as quickly. Without a robust data integration strategy, this leads to:

• Data redundancies and inconsistencies
• Increased manual effort for reconciliation
• Hampered real-time decision-making
• Negative impacts on KPIs related to agility, efficiency, and customer satisfaction

These issues ultimately result in misaligned insights, delayed responses, and a breakdown in trust around enterprise data. In other words, innovation slows down, and customer experiences suffer.

Organizations relying on multiple applications need reliable systems that ensure data consistency, accuracy, and real-time availability across all platforms. This is where Mendix Data Hub comes into play.

Why Mendix?

Its open and extensible architecture supports seamless data connectivity, significantly reducing the technical complexity of integrating disparate systems. Whether you're a small team or a large enterprise, Mendix provides scalability and enterprise-grade performance.

Key benefits include:

• Faster application development with built-in data integration
• Enhanced collaboration between business and IT
• Reduced data redundancy through centralized master data
• Improved operational efficiency by eliminating manual data handling
• Streamlined digital operations aligned with business processes

With Mendix, teams can rapidly build solutions that meet both business needs and IT governance standards, making it ideal for organizations looking to scale their digital initiatives quickly.

Introducing Mendix data hub

Mendix Data Hub enhances the core platform by addressing integration challenges directly. It simplifies how developers discover, understand, and use data across various applications.

Key features:

• Data hub catalog: Acts as a metadata repository, helping users locate and understand data within connected ecosystems.
• Studio pro integration: Developers can search, preview, and drag-and-drop external entities directly into domain models.
• OData services: Enables scalable and interoperable architecture by consuming external data through standardized services.

By creating a unified, consistent, and secure data layer, Mendix Data Hub significantly reduces the effort required to manage and integrate data across systems. This allows teams to focus more on building features and less on solving backend data issues.

Real-world example: telecom transformation

A leading telecom enterprise faced the common challenge of having multiple applications operating in silos. This led to:

• Duplicated data across platforms
• Inconsistent and fragmented reporting
• Complex integrations between legacy and modern systems

They needed a centralized solution to streamline master data management, reduce integration overhead, and improve reporting accuracy and operational agility.

Nagarro’s approach

The telecom provider partnered with Nagarro to implement a robust data integration framework using Mendix Data Hub. By leveraging our agile development approach, the solution delivered:

• Real-time access to shared master data
• A single source of truth across applications
• Elimination of redundant data storage
• Scalable architecture for future application rollouts

Implementation highlights

Data hub architecture

Nagarro designed and deployed a centralized data hub that eliminated silos and reduced integration complexity. Key capabilities included:

• Centralized repository: Ensured master data consistency
• OData-based integration: Allowed dynamic consumption of external entities
• Automated syncing: APIs facilitated real-time data updates between ERP systems and Mendix apps
• Role-based access: Maintained security and flexibility for different business users

This architecture enabled faster processing, fewer errors, and improved audit readiness. Developers could now focus on business logic rather than integration challenges, accelerating delivery cycles.

Business impact

The transformation delivered significant benefits:

• Improved data accuracy: Real-time access to trusted data enhanced analytics and decision-making.
• Reduced development effort: Reusable services simplified integration and allowed faster iterations.
• Faster time-to-market: Applications launched quicker by tapping into existing data sources.
• Lower maintenance costs: Centralized access reduced data duplication and technical debt.
• Enhanced user experience: Instant data availability improved dashboards and workflows.
• Future-ready flexibility: Supported both legacy compatibility and future expansion.

Additionally, the data hub created a more agile and responsive environment for both technical and business users. With centralized data access, cross-functional teams could collaborate more effectively and innovate without being held back by data silos or inconsistent reporting mechanisms.

Overcoming common integration hurdles

While Mendix Data Hub streamlines data access and management, it’s important to be aware of certain limitations:

• OQL incompatibility: Since external entities are fetched at runtime, they can't be used in OQL queries. This limits advanced server-side filtering.
• Read-only external entities: These cannot store data locally, which restricts their use in complex relationships.

To address these, Nagarro employed hybrid models that combine persisted and external entities. This approach enables critical data to be cached for operations that require high performance, while still allowing for real-time access to meet other needs.

Best practices applied

To maximize performance and scalability, Nagarro applied architectural best practices:

• Structured domain models with clear separation of concerns
• Reusable integration components for maintainability
• Interface segregation and smart caching for optimized runtime performance

These optimizations ensured the solution met enterprise standards for security, data integrity, and compliance. As a result, the client could confidently scale their operations and expand their application ecosystem without compromising on performance or data quality.

Conclusion: The future of integrated low-code ecosystems

As digital transformation accelerates, the need for scalable and efficient data integration becomes critical. Mendix Data Hub offers a powerful, low-code way to unify multi-app ecosystems, eliminate data silos, and enable real-time insights across platforms.

With the right implementation strategy and best practices, organizations can unlock new levels of operational efficiency, agility, and customer satisfaction. Centralized data management not only supports better decision-making but also reduces the total cost of ownership for IT systems in the long term.

Nagarro brings deep expertise in low-code development and data architecture to help enterprises modernize their digital ecosystems. Whether you're looking to integrate legacy systems or scale new solutions, we ensure your data remains consistent, secure, and actionable.
