Adding new product fields from the SQL database

[Paddymcc]

We sell refurbished laptops through our store so we are looking to modify the template slightly so we have fields which are pretty much common for all our products.

 

We want it to show:

 

Strap line

Processor

RAM

Hard drive

 

To give a quick summary of the machine before a customer would click into the product to ready further.

 

Ive gone into the database to add these fields to the Product_description table however which PHP files do i need to modify to get the fields displayed in Admin and subsequentially displayed on the site?
