Challenging Compare and validate question -- plus speed.
I have a tab delimited HUGE file (13 million records) with Detail, Metadata and Summary records.

Sample File looks like this

M BESTWESTERN 4 ACTIVITY_CNT_L12 A 3
M AIRTRAN 4 ACTIVITY_CNT_L12 A 3
D BESTWESTERN FIRSTNAME LASTNAME 209 N SANBORN AVE
D BESTWESTERN FIRSTNAME LASTNAME 6997 COUNTY ROAD D
D AIRTRAN FIRSTNAME LASTNAME 6997 COUNTY ROAD D
S BESTWESTERN 2
S AIRTRAN 2

I have split the file into three different files.

Metadata file
Detail file
Summary file

The challenge is to check if the information in Metadata records exist in the Detail record file. The names are not constant and WILL change with every incoming file.

1) The script needs to dynamically check the column in the Metadata record file that contains, for example 'BESTWESTERN' and 'AIRTRAN' and make sure that it also exists in the detail record file.

This is a huge file and need to know the fastest way to process it.

What is the best way to approach this dynamically changing file?
Please advice...

Thank You,
Madhu
