If you have to build your database by hand, the best structure is to have a database entry system that allows you to scan the UPC on a product and then key in the description. That way you make use of the UPC bar code for at least some of the data entry. Color ink and/or colored paper will reduce the contrast between the bars and spaces.
In addition, the UCC has a program where companies can buy a few numbers, but it is not a good deal. Code 93 is not as widely used but would provide an even higher density than either Code 39 or Code 128. For 12 characters of data, keyboard entry takes 6 seconds.
