Demo "Aplikasi Database Sekolah" menggunakan netbeans dan MySql

Summary

In this video, Erfani Delina presents her final project for the Programming Languages course at STMIK Hang Tuah Pekanbaru. The project is a school database application developed using NetBeans, featuring login functionality, data management for teachers and students, and average grade calculations. Erfani demonstrates how the application interacts with a MySQL database to manage data such as teacher and student details, grades, and personal information. She also explains the backend coding, including database connections and CRUD operations like saving, updating, and deleting records. The project aims to integrate seamless interaction between the frontend and database for efficient data management in a school system.

Takeaways

• 😀 The project is a school database application developed using NetBeans and MySQL.
• 😀 The application involves functionalities such as login, CRUD operations (Create, Read, Update, Delete), and grade tracking for students and teachers.
• 😀 The login system requires a username and password, which are validated against the database to authenticate users.
• 😀 Users are redirected to the main form once logged in successfully, where they can interact with teacher and student data.
• 😀 CRUD operations allow users to add, edit, and delete data for teachers (guru) and students (siswa) in the database.
• 😀 The system also displays student grades and calculates their average scores, showing how data is fetched and displayed from the database.
• 😀 The code involves importing libraries to connect NetBeans with MySQL for database interaction.
• 😀 Various functions in the project are triggered by button clicks, such as saving, updating, deleting, and searching data in the database.
• 😀 The form's design includes input fields for personal and academic details, and the application supports real-time data changes reflected in the UI.
• 😀 The project's database consists of four main tables: 'guru' (teachers), 'login' (user authentication), 'nilai rata-rata' (average grades), and 'siswa' (students).

Q & A

What is the purpose of the project described in the script?

The project is a school database application developed using NetBeans and MySQL. It aims to manage and display data related to teachers, students, and grades, providing functionalities such as login authentication, data search, update, delete, and display.

How does the login functionality work in the application?

The login functionality requires users to input a username and password. These credentials must match those stored in the database. If the input is incorrect, an error message is displayed asking the user to enter the correct username and password. If the credentials are correct, the user is directed to the main form of the application.

What happens in the main form of the application?

In the main form, various data related to teachers and students are displayed, such as teacher ID, name, gender, address, and phone number. Users can interact with the data using buttons for searching, updating, deleting, or saving changes to the information.

How is data updated or deleted in the application?

Data can be updated or deleted by selecting the appropriate entry in the form. For example, a user's address or other details can be changed by editing the relevant field, and then clicking the 'update' or 'save' button. The 'delete' button removes the selected record from the database.

Can you explain how the database tables are structured?

The database contains four main tables: 1) 'Guru' (teachers) – stores teacher-related data, 2) 'Siswa' (students) – stores student information, 3) 'Nilai' (grades) – stores students' grades, and 4) 'Login' – stores user login credentials such as username and password.

What is the purpose of the 'Nilai' (grades) table?

The 'Nilai' table stores data related to student grades, including attendance, assignments, and final scores. This data is used to calculate the average grade for each student, which can be displayed in the application.

How does the application handle displaying student grades?

The application retrieves and displays student grades based on data from the 'Nilai' table. It calculates the average score for each student using their attendance and assignment scores and shows this information in the form.

What role does MySQL play in the application?

MySQL serves as the backend database for the application. It stores all the necessary data (teachers, students, grades, and login credentials) and is accessed by the application through a connection to retrieve, display, and update data as required.

What are the key components of the code that link the NetBeans application to the MySQL database?

The key components include importing the MySQL library into the NetBeans project, establishing a connection between the application and the database, and implementing methods such as 'tampilData' (display data) for retrieving and showing data, along with functions for updating, saving, and deleting records.

What happens if a user tries to enter incorrect login credentials?

If the username or password entered by the user does not match the credentials stored in the database, the application will display an error message instructing the user to enter the correct username and password.
