English Gardens require a design for a database to keep records of their plant centres, the plants stocked at each plant centre and their customers. A plant may be an inside plant or an outside plant. An outside plant is either a shrub, perennial or annual. A plant may be at several plant centres and the quantity in stock is recorded. Details of the customers are recorded including their orders. An order contains all the plants ordered, the customer details, and the plant centre in which the order was taken.
