create ER-diagram for the following system

Snatch n Grab is a small groceries store, which has been getting a lot of attention recently, and the

owner has decided to expand his business.

The owner has requested you to create an Inventory Management System for his store. This system

will allow his employees to manage the store's inventory, and should contain the following features:

• Allow entry of new items

• Categorize items into groups, such as dairy/produce/fruits/vegetables etc.

• Allow entry of suppliers

• Allow entry of shipments

• Automatic request for restocking inventory

The way the store operates, is that after a deal is made between the store and a supplier, the supplier is

assigned certain items from the inventory. The supplier is then responsible for maintaining the stock

of said items in the store. Previously, the employees had to manually request the suppliers to restock

their items, but the owner wishes your application will be able to automate this process.

Multiple suppliers send multiple shipments, which contain multiple items for the store. All this need

to be organized and maintained.

Once the items reach the store, they are placed in appropriate counters, where customers may pick

them up and buy them. When a customer makes a purchase, the store records which item was sold and

when, and if the item inventory reaches a certain threshold (can be different per item), a request for

restock is generated.

If a new item is provided to the store, it needs to be cataloged along with its category, and sub category,

and then assigned to a supplier, and then finally confirm inventory size for the shop.
