I have got to write a standalone Java Program and the specifications are as follows:

The program takes inputs from Various files and Writes into different data sources . The intial inputs and the data sources are

The Inputs are

b)Comma Separated Text File

The Data Sources are

1.Oracle Data Source
2.An Active Directory

At a given point of time Only One input and One Output is valid and might change for each execution of the program.

There is a possibility of more input formats and Output data Sources. The other requirement is we can not change the already existing / tested code when we need to support new input formats and new output data sources. OfCourse we can write additional code.

The program is totaly based on OOPS concepts.

Please let me know how to go about it.

Your help is highly appreciated.

Thanking you in advance.
