Do you have a clearly described requirement? You will find many "inventory/stock control" type databases or templates online. But most will be too generic or too detailed to meet your specific needs. Based on your description, my guess is that you are not familiar with database principles nor design. I'm going to point you to a tutorial that will show you a technique for describing your requirement and translating that into tables and relationships suited to your situation. This
tutorial has a well described requirement, and a series of documented steps to identify tables and attributes; to build relationships and create a data model representing a database to meet the business needs. Once you have gone through the tutorial, you can apply the same approach to your business.
