How can I make a ONE model for edit delete update?

This is mysql databases on my project.

category|c_id
product|p_id|c_id
properties|pr_id|p_id

To clarify: the category table contained in the categories of products in the product table contains only those products in a table containing all the properties for The Nature products. The Nature of the products are very different for each product!

Sorry for my terrible English!

Code:

public function edit($table_name, $src_id, $id, $data)
{
    $this->db->where($src_id, $id);
    $this->db->update($table_name, $data);
}

Something like that.

Or have a look at Jamie's base model

Thank you for your help, but it comes to the table properties in which each row contains a characteristic driven from table product.
For example: a product "shoes" has 10 description, this means 10 lines in the table properties, and another product "hat" has two characteristics that means 2 rows in table properties.
So how how can I make a ONE model for edit delete update
