---|---|---|
Data transfer between two or more applications or synchronizing the data between two or more applications are done by interfaces.
Interfaces can be done by many ways, and few are listed below.
In a very simple interface system there will be one source and one destination application. All the validations are done during the data extract. Seeded validations are handled by the application. In a complex interface system, there will be more than one source and more than one destination instances. For example, in one of the project there is a requirement to synchronize the HR details between PeopleSoft, Oracle EBS, and SAP. BPEL process is used to transfer the data, translate to the respective application values, and synchronize between systems.
