1. Consider the Insurance database given below. The primary keys are underlined and the data types are specified:PERSON(driver-id:string,name:string,address:string) CAR(Regno:string,model:string,year:int)ACCIDINT(report-number:int,date:date,location:string)OWNS(driver-id:string,regno:string)PARTICIPATED(driver-id:string,regno:string,report-number:int,damage-amount:int)

1) create the above tables by properly specifying the primary keys and the foreign keys 2) Enter atleast five tuples for each relation 3) Demonstrate how you a) update the damage amount for the car with a specific regno in accident with report number 12 to 25000 b) add a new accident to the database 4) Find the total number of people who owned cars that were involved in accidents in 2002. 5) Find the number of accidents in which cars belonging to a specific model were Involved. 6) Generation of suitable reports 7) Create suitable front end for querying and display the results

1) create the above tables by properly specifying the primary keys and the foreign keys

2) enter atleast five tuples for each relation3) produce a listing:CUSTNAME,# of orders,AVG_ORDER_AMT,where the

middle column is the total no of orders by the customer and the last column is the average order amount for that customer

4) list the order # for orders that were shipped from all warehouses that the company has in a specified city

5) demonstrate how you delete item #10 from ITEM table and make the field null in the ORDER_ITEM table.

6) Generation of suitable reports.7) Create suitable front end for querying and displaying the results.
