Consider the Insurance database given below, where the primary keys are underlined. Assume each relation is filled with 10 tuples with all attributes having suitable domain-specific values and no null entries. Construct the following SQL queries for this relational database. person (driverid, name, address) car (license, model, year) accident (reportno, Adate, location) owns (driverid, license) participated (reportno, license, driverid, damage_amt) i. Find the number of accidents in which the cars belonging to “Karuna" were involved. ii. Update the damage amount for the car with the license number "KA15XL" in the accident with report number 52010 to 53000. Find out the location from which five or more accident cases are reported between iii. the time duration of 2016 to 2020.

PLz help with the following: Translate your ER diagram into a relational schema in the form of SQL DDLs. Choose appropriate data types for each attribute and include primary key and foreign key constraints, Check and Not Null constraints.
Suppose that A and B are two sets of entities connected by a relation R that has multiple one-to-one occurrences (see Figure 1). Think about a scenario in which R's generated connection is coupled with A's. SQL allows null values for attributes that are a part of a foreign key constraint. Give an example of how non-null constraints may be used in SQL to place a restriction on how much A can be involved in R.
