- Using the getSales() function as a reference, create a function thatt will take one parameter (string code) which is a product code (or part thereof), and when the search button is pressed, all sales that include this product code (or part thereof) will be displayed in the jTable. The date boxes in the GUI will be replaced with a text box. The schema of the database where the queries are being used is also attached. public List<Pos> getSales(String fromDate, String toDate){ List<Pos> salesList = new ArrayList<>(); try { String query = "SELECT sales_date, sales_number, prod_code, prod_name, unit_cost, quantity, sales_total " + "FROM Sales, SalesDetails, Product " + "WHERE Sales.sales_number = SalesDetails.sales_number " + "AND SalesDetails.prod_code = Product.prod_id " + "AND sales_date BETWEEN ? AND ?"; PreparedStatement stmt =…JAVA Script Create a form that has a last name, a first name, an email address, a drop-down listing of 10 cities in Massachusetts. The list is to be sorted (hint: think array), an email address, and a zip code field. Each field is to be process through a validation function. You may use one function for each but if you are creative you should be able to use just one function. The drop-down listing will not require validation because they will be choosing from a list that you are providing. This input from must be styled and show an effect to the user as to which field that are currently providing input.In this project you will implement a student database using JavaFX. A GUI should be used as the program's interface. This program must consist of two classes. (1) The first class should define the GUI and handle the database interactions: a. Combo box should allow the user to select one of the four database actions (Insert, Delete, Find, and Update). b. The database should be implemented as a HashMap, with the ID field as the key and a student record consisting of a name and major as the value. c. The operation should be performed when the user clicks the Process Request button. d. If the user attempts to insert a key that is already in the database an error message should be displayed using a JOptionPane message dialog box. e. If the user attempts to delete, find or update a record that is not in the database, a message should also be displayed. f. After each successful operation is completed a JOptionPane window should be…
- When the Search button is pressed in the screen depicted, the getSales() function from the PosDAO.java class is called, the parameters of this function are the from date and to date.The getSales () function should return a list of Pos objects that matches the criteria specified, Note this function has to perform two INNER JOINs in to combine all three tables in order to get all the needed data to fill the Pos object. The database schema is also depicted. The PosDAO, Product, SalesDetails and Pos classes are shown BELOW Write the getSales() function public class PosDAO { private Connection conn; PreparedStatement stmt = null; public boolean openConnection(){ try { // db parameters String url = "jdbc:mysql://localhost:4306/swen2005"; String user = "root"; String password = ""; // create a connection to the database conn = DriverManager.getConnection(url, user, password); if (conn!= null){ return true;…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…In this project, you will implement a single linked list structure that represents a list of Tawjihi records and do different operations on the records within that linked list. The inputs for the project will be the two Tawjihi files (One file for West Bank and the other for Gaza records). Each line in those files contains the Tawjihi record of a student (seat number, average, and branch). You may use the code you wrote/implemented during the lectrure to create and store Tawjihi record data into your single Linked List(s). You are free to use as many linked lists as needed. YOU MAY NOT USE ARRAYS IN THIS PROJECT. For good user experience, you will need to implement a user interface. In the user interface there should be a way to select between WestBank or Gaza as well as an option to select between branchs "Literary or Science". According to the previouse selction the following functions will operate in the specfic selected data above: 1. An option to insert new Tawjihi record into the…
- The 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. Reminder that the sales table SalesNumber field is set to AUTO-INCREMENT, hence the reason for only entering the total sales and current date in sales table.Create a structure course with some attributes i.e course_ID, course_title, credit_hrs etc.. Then Implement following 5 functions (Known as CRUDS operations which means CREATE, READ, UPDATE, DELETE, SEARCH operations): 1. addAStudent 2. updateAStudent 3. deleteAStudent 4. searchAndDisplayAStudent 5. displayAllstudents After that, create an array of 5 courses in main function.

- Build a list of contacts for New Jersey manufacturers as follows: ContactFirstName, ContactLastName, Phone. HINT: To do this you will need to split the contact name into two columns. You will need to embed string functions within string functions. It may be helpful to use Substring and Charindex. For last name, you can use a literal of 20 characters as the length to ensure you pick up all the characters to the end of the field.)At what point is it appropriate to build an index by hand?Open your text editor and create a new document named model.php model.php will contain functions that will connect to a database potentially return PDO statementobjects to the controller for processing. updateMessagesfunction updateMessages($id)This method will take a single parameter of id which is the saved id from the last or latest message displayed. It will conditionally select from the table “messages”, id, name, message, and time. The condition is that the field id is greater than the parameter for id. The return is the PDOStatement object with the row data from the query.
