true/false INNER JOIN combines two relations. It takes the second relation, and appends it to the end of the first relation. In Corelated Subqueries, subquery is executed independent of the outer query: subquery is executed only once. SELECT * FROM sys.Relations displays information about all the user-defined relations within a database. Given GENDER and STUDENT relations, SELECT Gender, FName, LName FROM GENDER LEFT OUTER JOIN STUDENT ON STUDENT.GenderCode = GENDER.GenderCode ≡ SELECT Gender,FName, LName FROM STUDENT RIGHT OUTER JOIN GENDER ON STUDENT.GenderCode = GENDER.GenderCode The statements select RIGHT('I wish I had attended the practice hours', 9) and select…
calculate_new_balance Given a starting balance (a number), and a list of transaction tuples, calculate the final balance for an account. Transaction tuples are of the shape ("description", amount, "withdrawal") , or ("description", amount, "deposit"). The last entry in the tuple will be either "withdrawal" or "deposit". Every withdrawal decreases the balance of the account by the specified amount, and every deposit increases the balance. The return value is the new account balance, as a number. (which could be negative) Sample calls should look like: >>> calculate_new_balance(100, [("payday", 20, "deposit"), ("new shoes", 50, "withdrawal"), ("illicit winnings", 200, "deposit")])270>>> calculate_new_balance(100, [])100

Task 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 MAINTENACE_TYPE_ID (char(5)) and a MAINTENANCE_TYPE_DESCRIPTION (varchar(30)) in the database. Using MAINTENANCE_TYPE_ID as the PRIMARY KEY, create a new table, MAINTENANCE_TYPES, and send the table description with the column names and types to the Car Maintenance team.
Population Database Compile and run CreateCityDB.java which will create a Java DB database named CityDB. The CityDB database will have a table named City, with the following columns: CityName & Population. Their Data Types: CHAR(50) Primary Key & DOUBLE. The CityName column stores the name of a city, and the Population column stores the population of that city. After you run the CreateCityDB.java program, the City table will contain 20 rows with various cities and their populations. Next, create an application that connects to the CityDB database and allows the user to select any of the following operations: Sort the list of cities by population, in ascending order. Sort the list of cities by population, in descending order. Sort the list of cities by name. Get the total population of all the cities. Get the average population of all the cities. Get the highest population. Get the lowest population. CreateCityDB.java import java.sql.*; /** This program creates the CityDB…
