Task 1in Regards To Part 1 Of This Assessment Please Read The Fol

For Part 1 of this assessment, the task involves developing a program that connects to a MySQL database named "grading_db" on "localhost" using the username "grader" and password "abc". The program must initialize the database tables at startup, with an option to skip re-creating them if they already exist to preserve existing data. The application should include functionalities for inserting student records, searching for student data, and displaying the student's marks along with the total final score, calculated as specified in the assignment outline. The user interface may be a command-line menu or GUI with a button to trigger table creation.

The first part of the assignment centers on creating a database-connected application that manages student grading information. The primary technical requirement is to establish a connection between the program and a MySQL database named "grading_db" hosted locally. Proper connection setup involves providing the correct hostname, username, and password, which are "localhost," "grader," and "abc," respectively. Establishing this connection is foundational, as subsequent functionalities depend on database interactions.

The program must include an initial database setup step, where tables are created if they do not already exist. This step can be implemented either as a button in a graphical user interface, a menu option in a console application, or an automatic process that runs upon program startup. To promote data integrity, the program should incorporate a check mechanism that determines whether the tables already exist in "grading_db" before attempting to create them. This approach prevents accidental deletion or overwriting of existing student data, which is crucial in a real-world educational setting.

Following the setup, the application should provide mechanisms for data entry, allowing users to insert new student records into the database. The data entry interface can be a simple form or command-line prompts. Furthermore, the application must facilitate searching for student records based on specified criteria, such as student ID, name, or class. When search results are displayed, they should include each student's marks and compute the total final score based on the formula outlined in the course subject outline. This calculation may involve summing individual assignment or exam scores with instructional weightings or other parameters specified in the assignment instructions.

Design considerations also include user interface ease-of-use and responsiveness. Whether implementing a GUI or command-line menu, the interface should be intuitive, providing clear options for each functionality. The search results should be presented in a readable format, detailing individual marks and the total final score for each student. The application must handle database exceptions gracefully to ensure robustness.

In summary, the core tasks involve database connectivity, table creation with existence checks, data insertion, and searching with calculated final scores. Proper implementation of these features will satisfy the assignment's requirements and demonstrate understanding of database operations, user interface design, and application logic.
