INTRODUCTION

Abstract

The Principles of Database Management course project involved developing a mental healthcare services system with several features These features included account creation, searching for disease symptoms and solutions, finding reservations with psychological specialists, and conducting mental health tests The project also emphasized creating a perfect database that adhered to the B.C normal form The database design process logically defined data entities, relationships, attributes, and constraints Achieving the B.C normal form ensured data integrity, eliminated anomalies, and optimized data retrieval and storage ("1NF, 2NF, 3NF, and BCNF in Database Normalization | Studytonight," n.d.) The logical design was meticulously crafted to ensure system efficiency, reliability, and scalability The database contained data uploaded by reputable organizations from around the world This ensured that the information stored in the database was credible and dependable The system's user interface was designed to be user-friendly, enabling easy access to various features The search function allowed users to find information about disease symptoms and solutions quickly The reservation system provided a straightforward way to schedule appointments with psychological specialists

The mental health test feature also allowed users to assess their mental health status Overall, the project provided a valuable opportunity to apply database management principles to a real-world problem in the field of mental health It underscored the significance of efficient and reliable data management in this domain The thoughtful approach to system features and design demonstrated a commitment to developing a robust mental healthcare system The project showcased the practical application of database management principles in addressing challenges in mental health.

System Overview

The global pandemic has profoundly impacted mental health, resulting in increased recognition of the importance of psychological therapy ("Depression," n.d.) In recent years, there has been a significant shift in attitudes towards therapy, with more individuals acknowledging its benefits and seeking professional help for their mental health concerns

However, accessing traditional therapy can still be challenging for many people due to factors such as long waitlists, high costs, and the enduring stigma associated with mental health ("Suicide mortality rate (per 100,000 population) | Data," n.d.)

To address these barriers and meet the growing demand for mental health services, online therapy platforms have emerged as a popular and accessible option These platforms offer a wide range of mental health services, including individual and group therapy sessions, online resources, and support from licensed therapists One of the critical advantages of online therapy is its flexibility, allowing individuals to schedule sessions at their convenience and receive therapy from the comfort of their homes Moreover, these platforms often offer more affordable pricing than traditional in-person therapy, making therapy accessible to a broader audience

Among the well-known online therapy platforms are BetterHelp, Talkspace, and Amwell BetterHelp provides various therapy options, including live sessions, messaging, and chat support Talkspace specializes in unlimited messaging therapy with licensed therapists On the other hand, Amwell offers mental health services as part of its broader telehealth platform, including access to medical doctors and specialists

The COVID-19 pandemic has further highlighted the significance of online therapy platforms With social distancing measures in place, many individuals have turned to these platforms to continue receiving mental health support Online therapy offers the added benefits of anonymity and privacy, which can be particularly appealing to those who may feel hesitant about seeking therapy in person due to stigma or other concerns

It is important to note that while online therapy platforms offer numerous advantages, they are not a substitute for traditional therapy, especially for individuals with severe mental health conditions These platforms, however, provide a valuable resource for individuals seeking mental health support, offering a convenient and accessible alternative to in-person therapy While they are not a replacement for all types of therapy, online platforms have become a valuable tool in supporting individuals' mental well-being and addressing the increased demand for psychological support in today's challenging times.

Goal

- Design the database to suit the requirements of Normalization BC Normal Form

- Connect the front-end interface (application) to the back-end database using a Java connection driver

- Develop the functions such as login, account creation, and booking; take a test using complex queries

- Evaluate the data and give more precise predictions in the future for the users

- Take security measures in the database to ensure robust privacy for the users' data and prevent any hacking into the system (known as SQL Injection).

The techniques & tools used

- SQL Server manages data in a relational database management system (RDBMS) using the SQL Server Management Studio and free hosting from www.freeasphosting,net, which stores our database remotely

- Java language using JetBrains IntelliJ IDEA GUI design the interface for users from the database and application logic flow

- Figma to design briefly about the interface

- Version Control System from GitHub to easily collaborate on the project

PROJECT ANALYSIS

Requirements Analysis

The proposed project aims to develop a comprehensive mental healthcare system with features including secure account login, password reset, and user roles for patients and specialists Users can access and extract data based on their role and request additions to the system's database Patients can take tests to identify psychological disorders and receive recommended solutions The system will provide information on common mental illnesses, symptoms, and potential solutions.

Approach Analysis

- Advanced SQL Server language structure ("SQL Tutorial," n.d.).

- Java, JDBC, Swing Worker official usage documents ("Lesson: JDBC Basics (The Java TM Tutorials > JDBC Database Access)," n.d.), ("SwingWorker (Java Platform S.E

The Scrum framework, a part of the Agile approach, has been adopted for the project Teams can deliver products using Scrum, which emphasizes adaptability and responsiveness to change in iterative and incremental stages It is frequently called an "agile project management framework" and concentrates on controlling circumstances to manage time and expense Traditional project management techniques, on the other hand, focus on set requirements to manage time and costs To support efficient project management, Scrum uses several strategies, including time boxes, group rituals, a prioritized product backlog, and regular feedback loops b) Process

The product backlog, which serves as a to-do list for the project, contains the features The team sets a sprint backlog with features and activities at the sprint planning meeting by choosing the product backlog items they think can be completed during the sprint period When the team decides on the sprint backlog, they begin working on the assigned tasks with a single, undivided concentration on reaching the sprint goal The product backlog can be altered before the start of the subsequent sprint, while the sprint backlog is left alone during the sprint

The team meets for a 15-minute scrum during the sprint to discuss remaining tasks, offer updates on their progress, and resolve any issues they encounter Each team member presents their work to the other members of the team, who provide insightful feedback that helps them plan the subsequent sprint and make required modifications The three Scrum pillars of transparency, inspection, and adaptability, which stress the value of open communication, ongoing review, and the capacity to adjust to changing conditions, serve as the framework for these meetings.

System Analysis

Figure 1 Primary Crow's Foot Format E.R.D Diagram

Figure 2 Schema design created by using SQL Server Moreover, our database has achieved the highest B.C normal form because of the following table:

1 N.F The database does not have any multivalued tuples

2 N.F All the non-key attributes depend on the primary key

3 N.F There are no transitive dependencies between non-key attributes

BC N.F Every non-trivial functional dependency in the database depends on a candidate key

This part discusses the database creation, schemas, and tables following the E.R.D the diagram in SQL Server Database: a Database Creation

3.3 Database Data Insertion a Source of data insertion

In general, the data insert into the database comes from three primary sources: o Self-generated data for testing purposes, as in Account, Patient, Specialist, HealingInformation o Look up the web for accurate data such as Disease, Symptom, Test, Question, AnswerSet, Answer, Result, and Solution ("FREE Mental Health Tests, Quizzes, Self-Assessments, & Screening Tools," 2022) o When the system goes public, the data from real user input is considered and validated before inputting into the database o We also have some update and removal procedures for users to make changes to suit their needs

In this report, the first five rows of each table are demonstrated to preview the data insert only, and the complete data can be found using the backup file attached to this report b Account Schema Account Table:

Our system users can create accounts with two roles: Patient and Specialist In addition, we provide several features, such as password change and display of the user's name in the welcome message

The following query is used to check if user login credentials are correct and exist in the database; this query returns the role also for later use in other queries

SELECT CASE WHEN A.User_ID=P.UserID AND P.UserID IS NOT NULL THEN 'Patient'

WHEN A.User_ID=S.UserID AND S.UserID IS NOT NULL THEN 'Specialist' ELSE NULL END

WHERE A.User_name=@UserName AND A.Password=HASHBYTES('SHA1', CONCAT(@Pwd, (SELECT A.Salt

FROM [Account].[Account] A WHERE A.User_name=@UserName)))

The following query is used to create an account for a user with the patient role, containing basic information such as account name, password, and personal information

The password is secured by adding a salt value after each password input to create a hash, which cannot be retrieved back to string one

SET @Salt=CONCAT(CHAR(FLOOR(RAND()* 10)+48), CHAR(FLOOR(RAND()* 26)+65),

CHAR(FLOOR(RAND()* 26)+97), CHAR(FLOOR(RAND()* 15)+33), CHAR(FLOOR(RAND()* 10)+48))

Application Java structure

For this project, the group has decided to use IntelliJ IDEA as an IDE to develop the application, which members have frequently used, and excellent community support when they get stuck This IDE also provides tools like SQL Console inside, Terminal, and

Debugging Tool for testing and assurance purposes when tackling hard-to-achieve tasks

When we first start the project, IntelliJ IDEA auto-generates the structure for the project, which is in the following figure:

Figure 3 The project structures in IDE

We can summarize the folders and files' purpose as follows: o idea: for storing IDE-specific project configurations (JDK level, the pattern, the structure, and many more) o out: the compiled code to run the application o sql: contains the SQL files used for database creation o src: the project's source code mainly contains the class and frm files used by G.U.I Designer o gitgnore, mindfulness.iml, README.md: used for project setup on GitHub Version Control System and provide based configuration per developers

Taking a closer look at each class used, we have the following UML Diagram to show the dependence of each class on others and provide a quicker view of the methods implementations

Figure 4 UML Diagram of the project

We can declare the class purpose as follows, as their corresponding class controls each frame, which we will discuss later in the G.U.I parts: o ConnectSQL.java: manages all the databases connection and return result from the query o Main.java: manages the main() function; we use this class to start the application process public class Main { public static void main(String[] args) { frmIndex.getInstance().setVisible(true);

} o frmBooking.java: manages the BOOKING frame and logic for buttons inside it for reservation booking functions o frmExplorer.java: manages the EXPLORER frame and logic for buttons inside it for admin query functions o frmIndex.java: manages the INDEX frame and logic for buttons inside it for signup/login functions This returns values to use in other methods as well o frmPatientDashboard.java: manages the PATIENT DASHBOARD frame and logic for buttons inside it for patient users o frmPatientSign.java: manages the PATIENT SIGNUP frame and logic for buttons inside it for patient registration o frmRoles.java: manages the ROLES frame and logic for buttons inside it for the role chooser function o frmSignDone.java: manages the SIGNUP DONE frame and logic for buttons inside it to take the user back to the index frame o frmSpecialistDashboard.java: manages the SPECIALIST

DASHBOARD frame and logic for buttons inside it for specialist users o frmSpecialistSign.java: manages the SPECIALIST SIGNUP frame and logic for buttons inside it for specialist registration o frmTest.java: manages the TEST frame and logic for buttons inside it for patients to take tests in the system

First, we go to the www.freeasphosting.net website to create a remote database like the figure below:

Figure 5 Free database hosting website for the project

Then we connect to the database (for use in the IDE) using the information provided and run the CREATE DATABASE, CREATE TABLE, and INSERT INTO queries above to begin initializing our database

Figure 6 Testing connection with the database

After doing all the creation, it is time to implement our ConnectSQL.java class to manage all the queries used in the project First is to import the JDBC Driver using and setting the connection URL of: import java.sql.*; import net.proteanit.sql.DbUtils; static final String connectionUrl =

"jdbc:sqlserver://sql.bsite.net\\MSSQL2016;databaseName=congbang0711_;user=con gbang0711_;password=mindfulness;encrypt=true;trustServerCertificate=true;";

Then, there are some methods to help with closing connections and displaying the result in tabular form: public static void closeConnect(Connection con) { if (con != null) { try { con.close();

System.out.println("Error closing connection");

} private static TableModel resultSetToTableModel(ResultSet rs) { try {

ResultSetMetaData metadata = rs.getMetaData(); int numberOfColumn = metadata.getColumnCount();

Vector headline = new Vector(); for (int i = 0; i < numberOfColumn; ++i) { headline.addElement(metadata.getColumnLabel(i + 1));

Vector content = new Vector(); while (rs.next()) {

Vector row = new Vector(); for (int i = 1; i 0) { isUpdated = true;

Next, we can begin to design the frames for Graphical User Interface directly on IntelliJ IDEA GUI Designer, as follows:

Figure 7 Create a new G.U.I Form in IDE From then, we can drag-and-drop the elements to the JFrame created; some of the frequent usages are:

Figure 8 G.U.I Designer Form for making a reservation o HSpacer, VSpacer: to add spacing between the elements o JPanel: to add a frame for other elements, it must be extended from our frame classes public class frmPatientDashboard extends JFrame o JButton: add a button with ActionListeners to perform logical code when clicking (discuss more in the later part) o JScrollPane: add a frame that can be scrollable, especially for long content o JLabel: to add title and instruction on the interface o JTextField, JPasswordField: to receive user input on the interface; the latter is used for the password field to protect privacy txtField.getText() txtField.setText("");

String.valueOf(pwdField.getPassword()) pwdField.setText(""); o JTextArea: to display the message after the query has been done txtArea.selectAll(); txtArea.replaceSelection(""); txtArea.setText(""); txtArea.setEditable(false); o JComboBox: to make a drop-down list for the user to choose from comboBox.setModel(new DefaultComboBoxModel(questions)); o JTable: to display the query result in tabular form table.setModel(Objects requireNonNull ( resultSetToTableModel (rs))); o JOptionPane: to display the dialog for the user to interact with

JOptionPane.showMessageDialog( null, "Field(s) are empty!", "Warning", JOptionPane.WARNING_MESSAGE);

JOptionPane.INFORMATION_MESSAGE); int option =

"Please check the information carefully!",

Object[] message = {"Master password: ", masterPwd}; int option =

To initialize the frames, we will use the constructor provided; with the use of the Singleton Design Pattern, we can save time by not reloading all the elements again as: o Default constructor public frmTest() { setContentPane(panel); setTitle("mindfulNESS - Self-diagnosis test"); setSize(1200, 800); setLocationRelativeTo(null); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

} frmTest frmTest = new frmTest(); frmTest.setVisible(true); setVisible(false); o Singleton constructor private static frmIndex instance; private frmIndex() { setContentPane(panel); setTitle("mindfulNESS - Homepage"); setSize(800, 800); setLocationRelativeTo(null); setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

} public static synchronized frmIndex getInstance() { if (instance == null) { instance = new frmIndex();

} frmIndex.getInstance().setVisible(true); setVisible(false); o Frame class that returns a value also has these methods public String[] getID() { return results;

} o The frame that needs to be loaded with content uses these methods:

@Override public void setVisible(boolean visible) { super.setVisible(visible); if (isVisible()) { pwdField.setText("");

All together, they are put inside a class that runs like this with all the variables and methods for working: public class frmPatientDashboard extends JFrame {}

As many buttons need to be implemented, we will only show some common patterns for this button Note that all buttons have the logic to validate user input (blank, not long enough, duplicate, etc ) and follow the SwingWorker design pattern: o Log in, sign up buttons: use user input (account, password) for authentication and perform the subsequent actions o Run the query, Search buttons: to run the query and return the result to the interface runQueryButton.addActionListener( e -> { runQueryButton.setEnabled(false); if (queryField.getText().isEmpty()) {

JOptionPane.showMessageDialog( null, "Please do not leave query blank!", "Warning",

JOptionPane.WARNING_MESSAGE); runQueryButton.setEnabled(true); return;

SwingWorker worker = new SwingWorker() {

ConnectSQL.showQuery(queryField.getText(), resultTable); return null;

@Override protected void done() { runQueryButton.setEnabled(true);

}); o Place a booking, confirm registering, and Post booking information buttons: to put the user input into the database o Patient, Specialist Place healing Mode, Explorer Mode, and Self-test Mode buttons: to set them according to the visible frame and dispose of the current frame healButton.addActionListener( e -> { healButton.setEnabled(false);

SwingWorker worker = new SwingWorker() {

@Override protected Void doInBackground() { frmBooking frmBooking = new frmBooking(); frmBooking.setVisible(true); setVisible(false); return null;

@Override protected void done() { healButton.setEnabled(true);

CONCLUSION

Achieved goals

During the project, our team successfully achieved the goal of developing the mental healthcare system Firstly, we designed the database to adhere to the requirements of B.C Normal Form, ensuring efficient data storage and retrieval while eliminating data anomalies Secondly, we connected the front-end interface of the application to the back-end database using a Java connection driver, establishing a seamless and secure connection between the user interface and the database Thirdly, we developed essential functions such as login, account creation, and booking, implementing complex queries to manage various scenarios effectively

Additionally, we incorporated data evaluation techniques to give users more precise predictions and recommendations for their mental health Finally, we implemented robust security measures in the database to safeguard users' data and prevent unauthorized access, including protection against SQL injection attacks Through completing these goals, our project has delivered a reliable and user-friendly mental healthcare system that meets the requirements of modern database management, security, and user experience.

Future work

The achievement of these goals opens exciting possibilities for the future evolution of this project into a fully-fledged real-world application Our team is committed to enhancing the user experience by implementing more advanced features We will introduce functionalities that allow users to update their information according to their preferences, expand the role of specialists to provide additional support and resources and improve the overall interface of the application Additionally, we aim to optimize the connection process, reducing user waiting times Furthermore, we plan to integrate a scheduling system into the app, enabling users to conveniently manage their therapy appointments and receive guidance throughout their treatment journey We will focus on continuous improvement and delivering a comprehensive and user-centric mental healthcare solution as we move forward.
