In 2024, we are signing another contract with the Ministry of Climate for the support, maintenance, and development of the Wykaz system.
The “Wykaz” IT System for Environmental Protection
As stated on the Ministry’s website, the “Wykaz” IT system (publicly accessible data register) is a comprehensive database and web application. It includes documents collected in departments and divisions, such as administrative decisions related to environmental matters and protection. These documents include, but are not limited to:
- Emission permits,
- Decisions related to waste generation and management,
- Permits for activities concerning protected species,
- Permits for running botanical gardens, zoos, or wildlife rehabilitation centers,
- Permits for activities concerning non-native species,
- Resolutions regarding appeals for projects within Natura 2000 areas,
- Environmental declarations (EMAS),
- Decisions denying access to environmental information,
- Environmental impact forecasts, reports, reviews, and specific expert analyses.
Our Maintenance and Development Work
Our daily work primarily focuses on ensuring the stability of this dedicated system, its reliability, and implementing improvements to enhance the user experience on the platform.
In 2018, we upgraded key components of the application, including the RedHat system, Oracle database, and Java. The main challenge in developing this application lies in the complexity of the entire system, as well as the size of the database, which contains approximately 30 million records.
The Legacy Technology Stack (Java 6 and Oracle)
Work on this system requires expertise in a specific legacy technology stack:
- Programming in Java 6
- JBoss
- Oracle DB
- JSF
- Ant
- RedHat
We are proud to continue our 7-year partnership with the Ministry of Climate, ensuring this critical IT system remains stable and reliable.
