Difference between interface and conversion in oracle apps

legacy system:
****************
System other than oracle is legacy system.
Ex:Spread sheet.

Interface:
***********
1)It is a program to transfer the data from one location to another location.
2)Interface is used to transfer the data from legacy system to oracle system.

Interfaces  are 2 types
1)Inbound interface: These interfaces are used to transfer the data from external system to oracle applications.
2)outbound interface:These interfaces are used to transfer the data from oracle applications to external systems.

Conversion:
************
Conversion is to bring the data from other(non-oracle apps) system to oracle application system.
Conversion is receiving the data from legacy system.

**************************************************************
INTERFACE:-
***********
IT IS A PROGRAM TO TRANSFER THE DATA FROM ONE LOCATION TO ANOTHER
LOCATION.
-->Interface is post production which is performed once before process.
-->interface is the integration of only(one way process)two systems.
-->interface is periodical process...
->IT IS SCHEDULED CONCURRENT PROCESS TO EXECUTED MULTIPLE TIMES
->WE WILL NOT BE KNOWING FLAT FILE VOLUME
->WE NEED TO HANDLE ALL EXPECTED EXCEPTIONS
->USED IN ENHANCEMENT,CUSTOMIZATION PROJECTS.


CONVERSION :-
****************
IT IS A PROGRAM
->IT IS ONE TIME DATA TRANSFER
-->it is one-time process.
-->data comes into oracle applications.
->WE WILL BE KNOWING THE VOLUME OF THE FLAT FILE
->NO NEED KNOW ALL EXCEPTIONS
->THIS IS USED IN UPGRADING,MIGRATION PROJECTS.


1)Open Interface: If the interface logic is provided by oracle applications,it is called Open interface.
******************
2)Custom Interface: If the interface logic is need to be developed by the implementation team, it is called Custom Interface.
