The reason I'm using a CSV file is that's what I'm given by my vendor. I'd love to not have to deal with a CSV file and just use a database but as this is only for reading, not writing to, it seemed like overkill to get the new file, read the file in, parse it, write it to a database, then have to deal with DBI overhead just to read some phone numbers out of the file and display them on a webpage.
