Adapters are software codes that communicate with source and target applications. Each adapter is designed to integrate with a specific target system (for example, Essbase or Financial Management) or source system (for example, Oracle E-Business Suite, or SQL). Workbench enables you to import and maintain the adapters used by FDM.

Target adapters are composed of an XML metadata component and a DLL or EXE. Other adapters are composed of an XML component only. The DLL or EXE components contain the system-specific instructions for interacting with the target system. The XML component contains all data that relates to the FDM application.
