Yeah I need help with my ER diagram.

Create a control inventory system ER diagram of a coffee shop that includes these 13 entities;

product, store, sells(store, product), customer, loyalty/individual,business account/ corporate, transaction, includes(transaction, product), purchase order/reorder, includes(reorder, product), supplier/ vendor, department, and region. Describe which are strong and weak entities, what are associative entities, which are super and sub classes. Specify cardinality constraints( min, max), identify attributes such as critical, unique, composite, multivalued, derived, and optional.
