i m using data integartion tools(ETL tools i.e. pervasive data integrator)

i want to implement real time integration.i have done it using window schedular but it is daily transformation of record.

so when change done on source table(i.e. add/delete/update action ),it should automatically reflect on target table at that time

how it will be done??? help me if anybody hav used that tool or hav some idea...
