Load the file into your application - you do not say what it is
Parse the data into a collection - you do not say what format the data is
Create a connection to the database - you do not say what your database is
Use either a stored procedure or text sql query to look for the existence of a matching record
Insert the record if there is no match
repeat for each item in the collection.
