Question Read a file line by line

I am relatively new to UNIX.
I am having a flat file with around 20,000 lines in it.
Basically, it is a dump of a database table with tab character as a delimeter.
I want to read the file row by row and process every row.

Any suggestions about achieving it efficiently??
Thanks
Smilie
