- In java create an application to manage your data base information the database is already created in mysql tables, the tables are fill, So the user can use your database application user friendly Retrieve all data: Given a table name, retrieve all data from the table and present it to the user. Average: Given a table name and a column name, return the average of the column. Here the assumption is that the column type will be numeric (e.g., cost column). Insert: Given a table name, your program should show the column names of that table and ask the users to input new data to the table. In case of errors, your program should directly show the MySQL errors to the users. Assumption 1: Users will enter data according to the database constraints. Assumption 2: Users will input one record at a time. Delete: Given a table name, your program should show the column names of that table and ask the users to input data that they want to delete. Assumption 1: Users will enter data according to the…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.

Unassigned lesson times (student ID is NULL) should not appear in the schedule.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
