Since you didnt give alot of info i will do my best,
From the sample you provided,
MAMMOGRAPHY INC,XXXXX1706,XXXXXXXX4708,
ABC INC.,XXXXX0742,XXXXXX2401,
It appears your dealing with comma separated values. Your best bet is to split on the comma

And the store the values in the appropriate columns in your database, with an insert

or an update

Hope that helps,
