Intrexx success story: Public administration

Federal City of Bonn

“Thanks to Intrexx, we were able to help our colleagues in the health department in a short time. With CovDi, new cases can be entered quickly and easily, and the employees always have an up-to-date overview and status of the processing.” 

David Adler, Head of E-Government, City of Bonn

Managing COVID-19 cases – Quickly and without paper

Use case: Process automation, Data integration
Industries: Public administration
Products: Connector for OData, Document Management for Intrexx, Individual applications

The COVID-19 pandemic poses enormous challenges to administrations. A large amount of data must be collected, processed and forwarded as quickly as possible. With Intrexx, the city of Bonn has built a clever digital solution that makes the health department staff’s work easier: the “Covid Digital” application, or "CovDi" for short. The solution was developed in record time and has proven to be an ace up their sleeve in the fight against COVID-19. The clever Bonn solution has also made other district authorities prick up their ears.

COVID-19 is a heavy burden for health departments: every new case must be recorded. The authorities must record and contact not only those who have been reported as infected but also their contacts. Added to this is the communication and coordination effort involved in imposing a quarantine.

Dealing with all this with paper and files was not a long-term option for the city of Bonn in 2020. But an “out-of-the-box solution”, a ready-made computer program, just was not available; the requirements were simply too complex and specific. Therefore, the city of Bonn simply created its own digital solution: With the low-code platform Intrexx, it took just four weeks after an initial discussion until a prototype was ready. After another two weeks, the go-ahead for the new “CovDi” application was given.

Quick overview – Without paper or traveling

The transition to “CovDi” was smooth and uncomplicated. The interface is self-explanatory for the most part: the health department staff enters the relevant data in a simple online form. This data is transferred to “CovDi” and is then available to all authorized persons for further processing. In this way, smear results, changes in the course of the infection or newly specified contact persons can be added and linked together in the system. Thanks to “CovDi”, citizen notifications can be prepared automatically with a simple mouse-click and then sent.

All this speeds up the work of the health departments considerably. After all, the “CovDi” app completely eliminates the need to access paper files. The database makes it possible to quickly check whether someone has already been added to the system or not. Furthermore, all the data and information already recorded is available and clearly laid out with just a few clicks. This means that citizens can be provided with fast and targeted information on the phone. The “Quarantine Team” also always has a real-time overview of the status of the people who must go into quarantine. The team must now no longer manually review case files every day.

Existing SharePoint data was imported with ease

Before they had “CovDi”, the cases in Bonn were first recorded on paper and then provisionally via SharePoint. The data from these transitional solutions – a total of almost 10,000 data records – was subsequently added to “CovDi” without much effort in order to ensure clean and complete data storage. In the further course of the pandemic, around 4,500 new cases were added via “CovDi” every month. However, thanks to the clean structure and clear layout, the health department staff can filter out the relevant information for their particular case at any time, even from this enormous mass of data.

Thanks to low-code, “CovDi” can continue to be improved

The best part of the low-code platform Intrexx, which was used to develop “CovDi”, is that new features can always be added over time. As a result, “CovDi” can be continuously fine-tuned while it continues to operate as normal.

The latest trick is a multi-import function for suspicious cases in schools and other public institutions. This means that the health department doesn’t need to add every single contact by hand but after a system-supported check, the data supplied by the institution is imported at the touch of a button and can therefore be processed and tracked quickly.

The new solution has also been used to digitalize the scheduling of the public health department: employees can now plan their working hours six weeks in advance in a socially responsible manner.

The clever solution from Bonn has received great interest from other city administrations. The digital data management system takes a huge load off the health department staff and makes their work easier, which is so important in these difficult times. To help other city administrations to go digital as well, the city of Bonn has made its own development freely available here at GitHub:


  • Rapid development even with individual requirements
  • Clean database structure
  • Ability to integrate existing data
  • Automated processes to notify citizens
  • Additional features can be added as needed
