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 strong REST API design and development, with reliable scalability, CPU efficiency, and integration with systems like SAP and Oracle Database. It enhances data processing and is valuable for banks needing service-oriented architecture. Despite its robust error handling and communication efficiency, scaling vertically is problematic, pricing is high for small companies, and inadequate documentation and support slow technical assistance. Improved data mining and XML conversion are needed.
