Architecture design

Hi,

I have to submit a java architecture solution for the following business problem.

Incoming file is in the form of xml it may contains maximum of 200K to 400K records.
Each record may interact with 10 external interface system to valiate the information with external system.
Result of interface response will be stored in to database.
After the completion of all recrods system should generate the report for the each record status.
This application does not involve any GUI.

What is the best way to implement this business logic with better performance.

Thanks for your time on this!
