The following relations kind a part of a on-line database (the relations area unit self-explanatory): CUSTOMER/CLIENT/SHOPPERS/BUYERS(Cust#, CAddress, Ctown, Balance,Cname) ORDER(Order.#, Date, Cust#.) ORDERLINE(Order#, Part#., Amount-Ordered) PART(Part#., Desc, Stock, Item-Class, Unit -Price) Design a physical ER for the above scenario. With respect to this relative schema, write SQL statements for the subsequent queries: List the name of the client United Nations agency has placed Order 123 (i.e. Order: = 123). List the names of shoppers United Nations agency in Cardiff and have ordered half 456 (i.e. Part. 456).

TASK 1 1. The InstantRide Management team founded a new team for car maintenance. The new team is responsible for the small maintenance operations for the cars in the InstantRide system. The main idea is to take actions faster and minimize the time spent for the maintenance. Therefore, the Car Maintenance team wants to store MAINTENANCE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, cook up a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team. Task: Make a new table to store car maintenance types. Task 2: The Car Maintenance team also wants to store the actual maintenance operations in the database. The team wants to start with a table to store CAR_ID (CHAR(5)), MAINTENANCE_TYPE_ID (CHAR(5)) and MAINTENANCE_DUE (DATE) date for the operation. Make a new table named MAINTENANCES. The PRIMARY_KEY should be the combination of the…
