With the help of the InstantRide mobile application, the users request a ride with their location. Drivers and cars are assigned to the request; and then the driver picks up the user to ride their requested location. Information for the users, drivers and cars are stored in the database as well as the travel transactions. In the USERS table, information for the users are stored with their first name, last name and email: In the DRIVERS table, all the drivers in the InstantRide are stored with their name, driving license number and check and rating information: In the CARS table, all the cars in the InstantRide system are kept with the license plate, model and year: Finally, the transactions of the rides are stored in the TRAVELS table. For each travel, start and end time with location are stored. In addition, the involved driver, car and…
Assignment Create a database in Access. In the database include the following tables: • Student info which has the following fields o First Name o Last Name o StudentID (primary key) • Courses table which includes the following fields: o CourselD (primary key) o Course Name o CRN • Schedule which contains the following fields: o StudentID o CourselD Create the proper relationships between the tables. Fill the tables with at least 5 students and 2 different classes. You can generate the data randomly by using the Mockaroo site Or you can review Extra Material for more links on how to generate random data Create a report to print out the course and the names of the students taking that course (so group by course). Make sure the report is well formatted, looks professional, include a professional header and a footer.
Task 5: The Developers team also wants you to ensure that emails are converted to lowercase after an update operation. Currently, new insertions are guaranteed to have lowercase emails, but there is no such guarantee for legacy emails. Therefore, the team wants to ensure that emails are being retained in a lowercase irrespective of any changes in the database. Create a new TRIGGER called email_update for the USERS table that runs before an UPDATE operation. Task: Create a TRIGGER to run on the USERS table before any UPDATE operation. (SQL Database Test): Create a TRIGGER before any UPDATE operations on the USERS table

The database should contain the following six tables: Artists (artist_id: char(30), artist_name: char(30), artist_pop: int(5))Tracks (track_id: char(30), track_name: char(30), duration: int(10), tempo:real) Record (artist_id: char(30), track_id: char(30))Users (user_id: char(30), user_name: char(30), age: int(5), nationality: char(30), num_track_listened: int(10))Listen (user_id: char(30), track_id: char(30))Follow (user_id: char(30), artist_id: char(30), follow_date: datetime) Write a single SQL query for each request below. Find the ids of those users who have listened to at least one track but have not followed any artists. Find the ids and names of those users who have listened to some tracks recorded by the artist named 'Adele'. Find the ids and names of those users who have not listened to any track recorded by the artist named 'Adele'. Use ''NOT EXISTS'' to answer this query.

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…
SCENARIO:A database contains information about ticket reservations for movie performances. To make a reservation you must be registered as a user of the system. In order to register you choose a unique username and enter your name, address, and telephone number (the address is optional). When you use the system later, you just have to enter your username. In the system, a number of theaters show movies. Each theater has a name and a number of (unnumbered) seats. A movie is described by its name only. (In a real system you would, of course, store more information, such as actor biographies, poster images, video clips, etc.) A movie may be shown several times, but then during different days. This means that each movie is shown at most once on any day. You can only reserve one ticket at a time to a performance (if you want several tickets for the same performance you must make several separate reservations) and cannot reserve more tickets than are available at a performance. When you make…
