Create a small Sports database with two tables: Team and Athlete. The Team table should include fields for the type of team (e.g., basketball), coach's name (both last and first), and the season the sport is most active (S for spring, F for Fall, or B for both). The Athlete table should include fields for student number, student first and last names, and type of sport. Use the same identifier for type of sport in both tables to enable the tables to be related and linked. Populate the tables with sporting teams from your school. Write a C# program that displays information about each team, including the names of the athletes. The data base we have provided to us just need to know how to program it in with the other guidelines given.

For each index i of data_list from 1 through the second-to-last index: The element at index i is a drop if the element is less than both the preceding element and the following element. If the element at index i is a drop, then output 'Drop: ', followed by the preceding element, the current element, and the following element, separating each element by a space.arrow_forwardThe Save Transaction button depicted in the screen attached is used to save relevant data to the sales table and the salesdetails tables from the depicted schema. When this button is clicked it calls the saveTransaction() function that is within the PosDAO class, it passes to this function an ArrayList of salesdetails object, this list contains the data entered into the jTable which is the products and qty being sold.Write the saveTransaction function. You are to loop through the items and get the total sales, next you are to insert the current date and the total sales into the sales table.
