This is what I got from your link to the hosting company on SQL databases.
Usually you would already have a database of the products that you wish to sell, and could download them into the SQL. If your mum uses Microsoft Access you could create a database in that and download it.
This is not an easy process, but if you have any database knowledge even Works Database, the principles are the same - it would be easier to show you, than tell you.
It would seem that you have to create a new database of the products that your mum wants to sell by keying in the information into this database as instructed below.
Hope this helps - Julie
Adding a MySQL database to your hosting package
If you have a Power, Unlimited or Bulk hosting package you can add MySQL databases to your website through the account control panel.
Step 1: Log into your account control panel.
Step 2: Click MySQL in the Product control section of the control panel.
Step 3: You will see a list of all the accounts you can add a database to. Create a new MySQL database by clicking Create.
Step 4: You will receive onscreen confirmation that the new database has been added to your account. This will also contain all the information required to access your database.
You can access your database with any MySQL administration tool you choose, or you can use the copy of phpMyAdmin we set up for you when you created your database. You can access phpMMyAdmin through your control panel by clicking the phpMyAdmin button in the Current mySQL databases section of your control panel.
Tip: More information regarding phpMyAdmin can be found in the products documentation at:
http://www.phpmyadmin.net.
Which version of MySQL am I using?
When you add your database in the account control panel, your database will be access to our latest SQL server, however if you have many different databases that you have created over time, it is possible that they will run on slightly different versions of MySQL. The versions are shown below:
MySQL1 to MySQL5 are running version 4.0.20.
MySQL6, MySQL7, MySQL8 are using version 4.1.15.
MySQL9 is using version 5.0.18.
MySQL10 and MySQL11 are using version 5.0.27
MySQL12, MYSQL13 and MYSQL14 are using version 5.0.22
