Q1. The following figure shows a shipping ticket sent to a customer. Draw an ERD reflecting the data contained in the shipping ticket. Note: (1) The ERD must have Customer (Customer ID as the PK), Manufacturer (Manufacturer Name as the PK). SalesOrder, Product and many other entities. (2) Assume that there is only one customer and one sales manager for each order. (3) No need to create a Recipient entity; recipient information must be attributes of SalesOrder. (4) The database must include unit price change history of products. (Hint: Create a ProductPrice entity to record all prices of products) The ERD must include not only entities and relationships with cardinalities but also all attributes. Underline the primary key. There must be no many-to-many relationships and no multi-valued attributes. Enter all foreign keys in the ERD. Q2. Convert the ERD you created inQ1into a relational database schema. Note: InQ1andQ2, only attributes are included in ERD and schema. Don't put real records in them. Please use the following format to draw ERD in Q1 Please use the following format to create the schema in Q2 This is what i've done, may i have some input for correction. Please give proper explanation and typed answer only.
