Simple PHP/MySql questions

I am currently learning php and Mysql and I have a few questions that I hoped the experts on here could answer.

I’m creating a job vacanies section of a clients site. They have 6 divsions in the company and want to show the jobs available for each divsion separately.

  1. Is it best practice to create six tables in one database. Then have 6 pages , one for each table, pulling out and displaying the data?

  2. I want my client to be able to delete jobs from the database. Should I show him how to delete them using PHP_MyAdmin or is there a simpler way to do it?

  3. Does anyone know a PHP script to allow people to browse from there comptuer and attach the files in the form?

Thank you
