Modernizing Legacy Applications with Oracle APEX and OCI

This case study outlines the modernization of a legacy Microsoft Access-based system used for managing critical business operations. The client sought to replace this outdated system with a scalable and secure solution while leveraging their existing Oracle Database license. The project aimed to develop a new Settlement Application using Oracle APEX, integrating it with other business systems through APIs and Single Sign-On (SSO). Key challenges included migrating from Microsoft Access without disrupting ongoing operations and implementing SSO for unified authentication. The solutions provided involved designing a custom Settlement Application with a low-code approach, migrating data and business logic to Oracle APEX, and ensuring seamless integration with existing applications. Additionally, secure REST APIs were built to facilitate data exchange, and performance optimizations were made to enhance user experience. The project resulted in significant improvements in system performance and reductions in IT operational costs, along with enhanced security and compliance measures.
