1. Develop a data manipulation application with a user-friendly JavaFX GUI for student's database (as shown in the ER diagram below). The user should be able to edit existing data and add new data to the database (obeying referential and entity integrity constraints). Allow the user to edit the database in the following ways: a) Add a new student. b) Edit the existing information for a student. c) Delete an existing student. d) Add a new course registration for a student. Student Registration Course id 1 studentid id name courseid major grade name semester room 2. Upgrade the application in Ql to provide an appropriate JavaFX to allow the user to perfom a query that is defined in a TextArea and the results will be shown in a Tableview. Sample predefined queries are: a) Select all students studying "Software Engineering" major. b) Select students who have excellent grades. c) Select all pass students in ascending order based on their names. d) For all students studying "Computer…
Q1/ A library service wants to create a database to store details ofits libraries, books and borrowers. Details include the following: A book has a unique ISBN number, a title and one or more authors. The library service may own several copies of a given book, each of which is located in one of the service's libraries. A given library contains many books, and in order to distinguish different copies of the same book a library assigns a different copy- number to each of its copies of a given book; the price that was paid for each copy is also recorded. Every library has a unique name and is either a main library or a branch library. A main library may have zero or more branch libraries and every branch library is a branch of exactly one main library. A borrower has a name and a unique ID code. A borrower can have many books on loan, but each copy of a book can only be on loan to one borrower. A borrower could borrow the same book on several occasions, butit is assumed that each such…
3.9 LAB - Select lesson schedule with inner join The database has three tables for tracking horse-riding lessons: Horse with columns: ID - primary key RegisteredName Breed Height BirthDate Student with columns: ID - primary key FirstName LastName Street City State Zip Phone EmailAddress LessonSchedule with columns: HorseID - partial primary key, foreign key references Horse(ID) StudentID - foreign key references Student(ID) LessonDateTime - partial primary key Write a SELECT statement to create a lesson schedule with the lesson date/time, horse ID, and the student's first and last names. Order the results in ascending order by lesson date/time, then by horse ID. Unassigned lesson times (student ID is NULL) should not appear in the schedule. Hint: Perform a join on the Student and LessonSchedule tables, matching the student IDs.

5. 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
1. You are asked to design a database for Banks. A bank will have one unique Code, Name andAddress. Banks will have multiple branches and each of those branches will be numbered (1,2..), first branch will be Number 1 for example and these will have an address of their own besides thebranch number. The Bank Branches will offer the option of creating accounts to customers, they willalso have the option of creating joint accounts. Customers will be able to open different accounts ineach of the bank branches. Account information will include the unique Account Number, TotalBalance and Account Type. The Bank Branches will also give Loans to Customers. Loans will haveunique Loan Number, Loan Amount and Loan Type. A customer can take multiple loans from acertain bank branch and banks can issue a number of different types of loans just like accounts. Thecustomer’s National_ID, Name, Phone and Address will be taken and stored. Using theseRequirements please construct an Entity-Relationship…

Please use C College StudentBibi is a lecturer who manages a student database at a university. Before Bibi existed, thestudent database was not well organized, and was not collected per student, so students’data could be chopped up and scattered irregularly between one another.Because Bibi is a lecturer who has studied “struct”, Bibi wants to store all the data givenin the struct. Making it easier to find and reuse.You are encouraged to use the struct method to solve this problem to make it easier tostore data.Data from students can contain:• Name (Nama)• NIM• Age (Umur)• Postal Code (Kode Pos)• Place of Birth (Tempat Lahir)• Date of Birth (Tanggal Lahir)• High School (Almamater SMA)• Number of Siblings (Jumlah Saudara Kandung)• Height (Tinggi Badan)• Bank Account Number (NOMOR REKENING)Format InputThe input in the first row contains an integer N , how much student data you have tosave.
