“In most of data migration projects I developed customized scripting processes.  I’ve developed BCP scripts along with Windows’ batch scripting to migrate data from flat files into Sybase database.  I used Oracle’s SQL Loader a lot to load ASCII data into Oracle server.  I also had a chance to user Siebel’s Enterprise Integration Manager (EIM) to convert data from external source into Siebel core database structure.”

ESB software tools are extremely complex, striving to openly connect a wide diversity of Web services, back-end corporate processes and data-driven applications. All ESBs are heavily based on open Web and XML standards, and they use open methodologies to provide a connective layer to multiple endpoints. All ESB software tools support for core SOA (service-oriented architecture) standards.

Among ESBs on the market, there is no fundamental difference. Everything an ESB does functionality-wise is similar because it is created based on open standards. However, ESB vendors are trying to differentiate themselves on the margins through better developer-oriented tools or easier integration with common back-end enterprise systems, or aggressive support of early drafts of proposed Web service and integration standards. The following ESBs are power players:
