Hi,
According to your description, there are three lists has a common field “BARCODE”, you might want to gather data from the three lists and populate into another list.
The available OOTB features would not be able to meet your requirement, I would suggest you achieve it in a way programmatically using SharePoint Object Model, CAML
query and Event Receiver.
With
SharePoint Object Model, we will able to access data in list/library:
SharePoint Object Model -
SPListItem class

Add, Update and Delete List Items Programmatically in SharePoint

More information about
SharePoint Object Model:

With
CAML query, it can help us query the data with some specific conditions:

The tool below would make it easier to compose query statement:

Event Receiver, we can use it to monitor the events such as when item created, when item deleted etc.
Here is a step by step sample on creating a simple Item added event receiver for Custom List in SharePoint 2010:

More information on Event Receiver for your reference:

Yes, to write the code, a Visual Studio installs on the machine which has SharePoint installed would be required, to get a quick start in SharePoint Development, I
would suggest you take a look at the links below:
