REM This program is used to export data in Oracle to external files named with current date.
REM A simple export schema is employed. Monday the data will be completely exported.
REM Tuesday through Thursday data will be exported in an incremental manner.
REM Friday, data exported include all the incremental data since the last completed export.
REM Saturday and Sunday incremental export will be employed once more.

REM This program can be used together with Windows plan and task utility. In that way,
REM the program can be enhanced with running by schedule.
