The factory design pattern creates objects.
The exact class of the object is unspecified.

The factory searches the project directory and gathers each product name.
The factory stores each product name inside a table.

If the user creates a product, the user enters the product name.
The factory creates the product from the name with reflection.

If the user creates many different product types, the factory accomodates.
The user does not evaluate each name case-by-case.
