I was wondering how a big company make a barcode system? Are there any barcode databases off the web that I could just download as a whole? And once I had one where would I go to update the already existing database?

They start by creating the database, then they write the software to put on the scanners, then they connect the two. Sounds like you need to do additional research. –  Ramhound May 2 '13 at 19:29
    
creating the database do you know where they load this data from? –  Andrew May 2 '13 at 19:44
    
stackoverflow.com/q/1050194/1338846 is about ready-made databases. However, every company must decide how they do it, there's many paths to the goal and methods often depends on predefined requirements. –  Sampo Sarrala May 2 '13 at 19:44
    
could you give a single path for a lay person –  Andrew May 2 '13 at 19:49
    
@Andrew - A lay person won't be able to do what you want. Companies simply load their data from their stock. The simplest way is to scan a single item of a particular stock number and set the price. –  Ramhound May 3 '13 at 10:50

Yes there are, take a look at question asked on StackOverflow: Database of commercial barcodes

It is all about ready-made databases. However, every company must decide how they do it, there's many paths to the goal and methods often depends on predefined requirements.

It seems that http://gepir.gs1.org has comprehensive database but I dont know if it is open for anyone. See another link for more of them.

Creating the database do you know where they load this data from?

They might "load" data from list of received goods :) Usually there's someone doing inquiries and orders, that guy already works on product database and therefore may as well enter new, update existing and remove obsolote data to/from database.

Final words...

There is no just one correct path to achieve so broad goal. Maybe you could provide some more information by edinting your question and explaining better what are you trying to accomplish.
