Importance of Database Design

In the development of a voting system, a good database design is crucial for ensuring the integrity and accuracy of the election process. A properly designed database can help prevent data inconsistencies, reduce data redundancy, and ensure data security. Additionally, a well-designed database can help streamline the voting process by ensuring quick and easy access to voter information, voting results, and other critical data points. This can help election officials to quickly and accurately report the results of the election and identify any discrepancies or issues that may arise.

A good database design can also enhance the transparency and accountability of the voting system. By ensuring that all data is accurately and securely recorded, it can help to build trust in the election process and ensure that voters have confidence in the results. Additionally, a well-designed database can help to prevent fraud or other attempts to manipulate the voting process by providing an auditable trail of all actions taken within the system. This can help to ensure that the voting process is fair, transparent, and free from outside influence.

Database Tables

A Voting System Database Design involves several database tables that store information about the various aspects of the voting process, such as the registered voters, candidates, positions, parties, and votes. The design of these tables plays a crucial role in the efficient functioning of the voting system, and it is essential to ensure that they are properly structured and optimized to handle large amounts of data and support complex queries.

The “tbluser” table is a database table that is commonly used in software development projects to store information about users of a system or application. It typically includes the following fields:

• id: a unique identifier for each user in the table
• username: the username that the user uses to log into the system
• password: the user’s password, which is usually encrypted for security purposes
• fullname: the user’s full name
• accesslevel: a field that specifies the level of access that the user has in the system, such as “administrator” or “user”.

By storing this information in a database table, the system can easily authenticate users and determine their level of access to different parts of the system. It also makes it easier to manage user accounts, such as adding new users, deleting old ones, or changing user permissions.

Create SQL Statement – the statement below is used to create the tbluser, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

CREATE TABLE tbluser (
id INT NOT NULL AUTO_INCREMENT,
username VARCHAR(50) NOT NULL,
password VARCHAR(255) NOT NULL,
fullname VARCHAR(100) NOT NULL,
accesslevel VARCHAR(50) NOT NULL,
PRIMARY KEY (id)
);

The “tblparty” table is a database table that stores information about political parties or groups. The fields in the table are:

• id: This is a unique identifier for each party in the table.
• partyname: This field stores the name of the political party or group.
• partydescription: This field contains a brief description of the party or group, such as its history, ideology, and platform.

Create SQL Statement – the statement below is used to create the tblparty, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

CREATE TABLE tblparty (
id INT NOT NULL AUTO_INCREMENT,
partyname VARCHAR(255) NOT NULL,
partydescription TEXT NOT NULL,
PRIMARY KEY (id)
);

The “tblcourse” table is a database table that stores information about courses in an educational institution or online learning platform.

• id – a unique identifier for each course
• courseinitial – the abbreviated name or code for the course
• coursename – the full name of the course

The “tblcourse” table may also include additional columns such as course description, credit hours, prerequisites, and other related information depending on the requirements of the system or application it is being used for. Overall, the “tblcourse” table provides a structured and organized way of managing and storing information about courses in a database.

Create SQL Statement – the statement below is used to create the tblcourse, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

CREATE TABLE tblcourse (
id INT NOT NULL PRIMARY KEY,
courseinitial VARCHAR(10) NOT NULL,
coursename VARCHAR(255) NOT NULL
);

The “tblstudent” table is a database table that stores information about students in a school or university. The meaning of each column is as follows:

• id – A unique identifier for each student in the table.
• studentidno – A unique identification number assigned to each student by the school or university.
• lastname – The last name or surname of the student.
• firstname – The first name of the student.
• middlename – The middle name of the student.
• courseid – The course that the student is enrolled in.
• votingcode – A unique code assigned to each student for voting purposes in the voting system.
• image – A column that stores the image or photo of the student.
• votestatus – A column that indicates whether the student has already voted or not in the voting system.

Create SQL Statement – the statement below is used to create the tblstudent, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

CREATE TABLE tblstudent (
id INT NOT NULL AUTO_INCREMENT,
studentidno VARCHAR(50) NOT NULL,
lastname VARCHAR(50) NOT NULL,
firstname VARCHAR(50) NOT NULL,
middlename VARCHAR(50),
courseid INT NOT NULL,
votingcode VARCHAR(50) NOT NULL,
image BLOB,
votestatus INT NOT NULL,
PRIMARY KEY (id)
);

The “tblcandidateposition” table is a database table that stores information about candidate positions in an election or voting system. The fields in this table are:

• id: a unique identifier for each candidate position
• positionname: the full name of the candidate position
• shortname: a shorter version of the name of the candidate position, typically used for display purposes
• sortorder: a number used to sort the candidate positions in a particular order
• votesallowed: the number of candidates that can be elected to the position
• allowperparty: a number value indicating how many are allowed from the same political party to run for this position.

This table is typically used in conjunction with other tables in the database, such as a table of candidates and a table of votes, to facilitate the voting process and ensure that the results of the election are accurate and valid.

Create SQL Statement – the statement below is used to create the tblcandidateposition, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

• id: This is a unique identifier for each candidate and is used as the primary key of the table.
• studentid: This field stores the ID number of the student who is running as a candidate.
• positionid: This field stores the position that the candidate is running for. It is a foreign key that references the “tblcandidateposition” table.
• partyid: This field stores the ID of the party that the candidate belongs to. It is a foreign key that references the “tblparty” table.

Create SQL Statement – the statement below is used to create the tblcandidate, copy the sql statement and paste it in the sql manager/tab of your phpmyadmin.

CREATE TABLE tblcandidate (
id INT NOT NULL AUTO_INCREMENT,
studentid INT NOT NULL,
positionid INT NOT NULL,
partyid INT NOT NULL,
PRIMARY KEY (id)
);

The “tblvote” table is a database table that stores information about votes cast by students in an election. It typically contains the following fields:

• id: A unique identifier for each vote in the system.
• studentid: The ID of the student who cast the vote.
• candidateid: The ID of the candidate who received the vote.
• date_recorded: The date on which the vote was recorded.
• time_recorded: The time at which the vote was recorded.

This table is important in the development of an election system, as it stores the records of each vote cast by a student, allowing the system to determine the winner of each position or election overall. It is crucial that the table is designed in a way that ensures the integrity and security of the voting system, such as ensuring that each student can only vote once and that votes cannot be altered after they have been cast. A well-designed “tblvote” table can help to ensure the accuracy and fairness of an election.
