Suppose each of the following operations is applied directly to the above database. Discuss all integrity constraints iolated by each operation if any. ✓ UPDATE Projects SET PID DM120' WHERE pID = 'DM220'; ✓ DELETE FROM Participate WHERE PID- DM220' AND WIDW103¹; ✓ INSERT INTO Projects VALUES ('DM220', 'Detecting DoS', 'Fourth Thousands'); ✓ INSERT INTO Workers VALUES ('W103', 'Ann Greens', '213 University Blvd.', '112-44-9878', '(336)888-3146'); A Reject, it violates the entity integrity constraint. B. Reject, it violates the referential integrity constraint C. Reject, it violates the domain constraint. D. Reject, it violates both the key constraint and referential integrity constraint. E. Reject, it violates the key constraint. F. Accept, it will update tuples in the Projects and Participate relations with p/D-DM22 G. Accept, there are no constraint violations.

The university contains many academic departments in a college, such as the Department of Computer Engineering, Software Engineering, and English Language Teaching etc. And a variety of courses are offered by each department. And possibly an instructor can teach more than one course. For example, a physics professor can teach math's also. You need to create a database schema for this application. Notice that the database users are varied corresponding to their privileges and interest. Assuming that you have DBA, end users etc. create database schema using any RDBMS (mysql, and postgresql are preferred). Insert few record as related to your courses and department. Notice that you need to show ER-Diagram, in the latest step. Note: you should include the .sql file and ERdiagram.jpeg and in your uploaded file / folder to the LMS, also the .sql file shall contains the inserted data to the relations
My current assignment is to work on a Access database for our college for clubs. Business rules are: Some students may join no clubs. Students can only join one club. There must be one student to be a club. I am having difficulties in establishing the above rules in Access. I think my relationships are incorrect. Please see attached.
Assume there is only one seat available in a class for which two students are registering. What prevents both students from being allocated to the final available seat in a database system?
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.
Assume that a student table in a university database had index on StudentID (the primary key) and indexes on Major, Age, MaritalStatus, and HomeZipCode (all secondary keys). Further, assume that the university wanted a list of students majoring in MIS or computer science, over age 25, and married OR students majoring in computer engineering, single, and from the 45462 zip code. How could indexes be used so that only records that satisfy this qualification are accessed?
