![]() Put simply, a bill of materials (BoM) is a listing of the materials and parts used to manufacturer some product. Awesome! What is a Bill of Material (BoM)?

It may not always be possible or desirable to include photos or images, but when applicable, pictures can be tremendously useful. Most people could easily create their own bill of materials spreadsheet from scratch, but hopefully this template will provide a useful example. But then I added a few other features, such as a revision history worksheet, to make the template more general.

The one-to-many relationship is only a principle of database design, which cannot be explicitly defined in the database structure. One, in this example, is one customer to many sales transactions. ![]() This logic is what is defined by the one-to-many relationship. A single sales transaction can only apply to one customer, but one customer can have many sales transactions over the course of time. The SALES table contains the CUST_ID foreign key, which references the column of the same name in the CUSTOMER table to track the customer to whom the sale was made.
