Project Summary

Dreamix upgraded CERN's role-based access control system, modernizing the architecture using React and Java. They replaced the legacy APEX UI, implemented a Spring + REST backend, and began migrating backend logic from PL/SQL to Java. The team implemented frequently requested user features and has run the new system alongside the legacy one to ensure a smooth transition; the project is progressing according to plan.

Key Challenges

  • Modernize the "Roles" role-based access control application used across CERN's administration and IT applications
  • Transition from Oracle APEX and PL/SQL to a modern React and Java architecture

Project Deliverables

  • Replaced the APEX user interface with a React-based UI
  • Implemented a Spring + REST backend
  • Migrated PL/SQL business logic progressively to Java
  • Delivered new user-requested features to improve functionality

Project Solution

The vendor replaced the Oracle APEX UI with a React front end and implemented a Spring + REST backend while retaining substantial PL/SQL logic initially. They subsequently began migrating remaining business logic from PL/SQL to Java and introduced new user-requested features to modernize the role-based access control system and ensure a seamless transition for users.

Project Outcome

  • Implemented the new system alongside the legacy system ensuring a smooth transition
  • Started a backend migration to Spring to improve performance and scalability
  • Incorporated frequently requested user features
  • Project is proceeding according to the planned timeline
