My favorite feature is the XML-based DFDL mapping, which is a tool that allows you to graphically map legacy data formats to modern data formats.
IBM Integration Bus offers easy deployment without code rewriting, adapting to specific needs. It efficiently integrates backend applications with minimal CPU usage and flexible API support, enhancing performance. Seamless communication is facilitated across platforms like SAP and Oracle, featuring robust transformation and routing. Though based on Eclipse, the toolkit could be more responsive. High licensing costs, complex migration, and limited orchestration support are drawbacks, along with scalability and stability challenges during testing.
