match (p:Product),(c:Category) where p.categoryID=c.categoryID create (p)-[:PART_OF]->(c)                                                                                   match (p:Product),(c:Supplier) where p.supplierID=s.supplierID create (s)-[:SUPPLIES]->(p)

（1）查询每个供应商生产的食品种类

match (s:Supplier)-->(:Product)-->(c:Category) return s.companyName as Company, collect(distinct c.categoryName) as Categories

（2）查找Produce供应商

match (c:Category{categoryName:'Produce'})<--(:Product)<--(s:Supplier) return distinct s.companyName as ProduceSuppliers
