Introduction:
In this tutorial, we will utilize HTML, CSS, and JavaScript to develop the Employees Database Management System, with detailed demonstrations provided in the following examples.
The goal of this tutorial is to apply three web development languages – HTML, CSS, and JavaScript – to create an Employee Database Management System (EDMS). While HTML establishes the basic structure, CSS ensures visual consistency, and JavaScript introduces interactivity to the website. Specifically, JavaScript will be utilized to construct a database management system for employees.
The primary goal of this workforce management system is to enhance productivity, streamline payroll administration, and provide businesses with a user-friendly solution for managing personnel.
In the current digital era, it is essential for businesses of various scales to keep abreast of technological advancements while managing employee information. Implementing an Employee Database Management System (EDMS) can enhance operational effectiveness and facilitate better decision-making by streamlining tasks like storing, categorizing, and accessing employee data. This results in user-friendly online tools that efficiently manage employee records with speed and precision.
Creating an Employee Database Management System utilizing HTML, CSS, and JavaScript involves the following steps:
Developing an Employee Database Management System (EDMS) with HTML, CSS, and JavaScript can present a fulfilling challenge. Below is a detailed guide on how you can tackle this project:
User Interface Design (HTML & CSS):
- Start by designing the user interface using HTML to structure the content and CSS to style it.
- Create different sections for displaying employee information, such as a table for listing employees and forms for adding, editing, and deleting employee records.
- Use CSS to make the interface visually appealing and user-friendly. Consider layout, color scheme, typography, and responsive design for various screen sizes.
Data Storage in JavaScript:
For this front-end task, JavaScript will be utilized to imitate data storage. One approach is to save employee details as objects in an array, while another option is to employ local Storage for retaining data on the user's browser.
Develop functions to manage CRUD (Create, Read, Update, and Delete) tasks on the employee information.
Functionality (JavaScript):
- Implement functionality to add new employees by capturing data from input fields and adding them to the data storage.
- Develop features for editing existing employee records, allowing users to modify employee details.
- Enable users to delete employee records, removing them from the data storage.
- Implement search and filter functionality to allow users to find specific employees based on criteria such as name, department, or position.
Presenting Data (JavaScript):
Develop the JavaScript functions responsible for dynamically creating HTML elements representing employee data to be shown on the user interface.
Utilize DOM manipulation techniques to modify the interface in response to user actions, such as adding, editing, or removing employee records.
Data validation in JavaScript involves incorporating validation checks on input fields as users input or add new employee records to ensure the presence of essential information like name, email, and phone number. This process includes providing feedback to users regarding any validation errors that need to be addressed.
JavaScript Interaction:
To enable user interaction, set up event listeners on buttons, forms, and inputs within the interface. Monitor user actions such as clicks, form inputs, and keyup events to enhance the flow of code within the application.
Testing and Troubleshooting:
- Thoroughly examine the application to confirm that all functionalities are operating correctly and fulfilling their intended purposes without any bugs or issues.
- Utilize browser developer tools extensively to identify and resolve any issues that may surface while preparing for testing.
Creating an accessible and user-friendly website involves adhering to web accessibility standards to accommodate users with disabilities. It is essential to prioritize seamless user experiences by focusing on intuitive interfaces and addressing any navigation challenges.
Documentation and Deployment:
- Offer a precise tutorial on the Employee Database Management Systems usage to ensure individuals will know the system.
- Set up the app on a web hosting service or via platforms such as GitHub Pages. It will enable others to step into it and try it out.
- Through the implementation of the next procedures, you will be able to develop a practical Employee Database Management System for users on a web browser. Employee's data will be managed in an efficient manner, which will be possible after completing these steps.
1. User Interface (UI) Design
1.1 The Structure of HTML
Our Employee Data Management System is structured using HTML (HyperText Markup Language). Below, we will describe the necessary elements for gathering and displaying employee information.
HTML Code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Employee Database Management System</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>Employee Database Management System</h1>
<h2>Add Employee</h2> <!-- New heading for the form action -->
<form id="employeeForm">
<label for="employeeName">Name:</label>
<input type="text" id="employeeName" placeholder="Name" required>
<label for="employeeDepartment">Department:</label>
<input type="text" id="employeeDepartment" placeholder="Department" required>
<label for="employeeAddress">Address:</label>
<input type="text" id="employeeAddress" placeholder="Address">
<label for="employeeSalary">Salary:</label>
<input type="number" id="employeeSalary" placeholder="Salary">
<label for="employeeEmail">Email:</label>
<input type="email" id="employeeEmail" placeholder="Email">
<label for="employeeContact">Contact Number:</label>
<input type="text" id="employeeContact" placeholder="Contact Number">
<button type="submit">Submit</button>
</form>
<!-- Employee List -->
<div id="employeeList"></div>
</div>
<script src="https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image"></script>
</body>
</html>
Explanation:
The code snippet above illustrates the fundamental layout of an HTML document for a basic Employee Database Management System. Let's delve into its explanation:
The creation of a webpage containing HTML code for an employee management system involves the inclusion of various components:
- A form designed to capture new employee data, including fields for name, department, address, salary, email address, and phone number. Completing this form and clicking the submission button is essential for adding new employees.
- A designated area where the list of employees is displayed, providing an overview of the current workforce.
- Integration of additional functionality through script.js and styles.css JavaScript files to enhance the website's features and visual presentation.
In essence, this code snippet establishes a basic user interface for managing employee records efficiently.
1.2 Using CSS for Style
Cascading Style Sheets, known as CSS, enhance the visual presentation and layout of the Electronic Document Management System (EDMS) user interface. To enhance the usability and aesthetic appeal, we will define specific styles.
CSS Code:
/* Reset default margin and padding */
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
/* Body styles */
body {
font-family: 'Segoe UI', Tahoma, Geneva, Verdana, sans-serif;
background-color: #f0f0f0;
}
/* Container styles */
.container {
max-width: 800px;
margin: 20px auto;
padding: 20px;
background-color: #fff;
border-radius: 20px;
box-shadow: 0 0 20px rgba(0, 0, 0, 0.1);
}
/* Heading styles */
h1 {
text-align: center;
color: #333;
margin-bottom: 20px;
}
h2 {
margin-top: 20px;
margin-bottom: 10px;
color: #333;
}
/* Form styles */
form {
margin-bottom: 20px;
}
label {
display: block;
margin-bottom: 10px;
color: #666;
font-weight: bold;
}
input[type="text"],
input[type="number"],
input[type="email"] {
width: calc(100% - 20px);
padding: 15px;
margin-bottom: 20px;
border: none;
border-radius: 10px;
background-color: #f5f5f5;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}
button {
width: 100%;
padding: 15px;
margin-top: 10px;
background-color: #4CAF50;
color: #fff;
border: none;
border-radius: 10px;
cursor: pointer;
transition: background-color 0.3s ease;
}
button:hover {
background-color: #45a049;
}
/* Employee list styles */
#employeeList {
margin-top: 20px;
}
.employee {
margin-bottom: 20px;
padding: 20px;
background-color: #f5f5f5;
border-radius: 10px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
}
.employee h3 {
margin-top: 0;
color: #333;
font-size: 18px;
}
.employee p {
color: #666;
font-size: 16px;
margin-bottom: 5px;
}
.deleteBtn,
.renameBtn {
padding: 10px;
margin-top: 10px;
background-color: #f44336;
color: #fff;
border: none;
border-radius: 10px;
cursor: pointer;
transition: background-color 0.3s ease;
}
.deleteBtn:hover,
.renameBtn:hover {
background-color: #d32f2f;
}
Explanation:
This code excerpt represents a CSS style sheet with formatting instructions for elements contained in an HTML file. Let's delve into it: Below is a CSS line implementing a border-box model to ensure precise scaling and resetting of both margins and paddings for all components. It specifies a specific font and background color for the body. The components within the container are appropriately structured within this card, defining properties such as width, margin, padding, border radius, and box-shadow. The font is adjusted with adequate spacing and positioned at the central part of the content. Common elements like box shadows, padding, and background colors are consistently styled for uniformity. Meanwhile, buttons share similar characteristics including background color, padding, and a transition effect upon hovering. Similarly, list items are styled with consistent properties like margins, padding, background color, border radius, and box shadow. The buttons for renaming and removal exhibit identical hover effects.
2. Using JavaScript to Implement Functionality:
JavaScript provides the capability to interact dynamically with the Electronic Document Management System (EDMS) for tasks like storing employee details, gathering input from users, and adjusting the user interface (UI) when required.
JS Code:
document.getElementById('employeeForm').addEventListener('submit', function(event) {
event.preventDefault();
let name = document.getElementById('employeeName').value;
let department = document.getElementById('employeeDepartment').value;
let address = document.getElementById('employeeAddress').value;
let salary = document.getElementById('employeeSalary').value;
let email = document.getElementById('employeeEmail').value;
let contact = document.getElementById('employeeContact').value;
if (name && department) {
addEmployee(name, department, address, salary, email, contact); // Call function to add employee
document.getElementById('employeeName').value = ''; // Clear input fields after submission
document.getElementById('employeeDepartment').value = '';
document.getElementById('employeeAddress').value = '';
document.getElementById('employeeSalary').value = '';
document.getElementById('employeeEmail').value = '';
document.getElementById('employeeContact').value = '';
} else {
alert('Please fill in all required fields.');
}
});
function addEmployee(name, department, address, salary, email, contact) {
let employeeList = document.getElementById('employeeList');
let employeeDiv = document.createElement('div');
employeeDiv.classList.add('employee');
employeeDiv.innerHTML = `
<h3>Name: ${name}</h3>
<p>Department: ${department}</p>
<p>Address: ${address}</p>
<p>Salary: ${salary}</p>
<p>Email: ${email}</p>
<p>Contact Number: ${contact}</p>
<button class="deleteBtn">Delete</button> <!-- Delete button for each employee -->
<button class="renameBtn">Rename</button> <!-- Rename button for each employee -->
`;
employeeList.appendChild(employeeDiv);
// Add an event listener for the delete button
employeeDiv.querySelector('.deleteBtn').addEventListener('click', function() {
employeeList.removeChild(employeeDiv); // Remove the employee entry from the list
});
// Add an event listener for rename button
employeeDiv.querySelector('.renameBtn').addEventListener('click', function() {
let newName = prompt('Enter new name:');
if (newName !== null && newName !== '') {
employeeDiv.querySelector('h3').textContent = `Name: ${newName}`;
}
});
}
Output:
This interface is designed for inputting employees' information into the Electronic Document Management System (EDMS):
This represents the user interface displaying the list of employees following the addition of employee details.
Explanation:
The following code snippet demonstrates the use of JavaScript logic to handle form submissions and dynamically insert employee details into a webpage. Let's examine this process:
This snippet of JavaScript code operates discreetly by setting up an event listener to trigger upon the submission of the employee form. It retrieves form data, validates the completion of mandatory fields, and intercepts the default form submission behavior. When the conditions are met, the input field is emptied prior to invoking the addEmployee function, which is linked to the aforementioned data. Failure to comply restricts the user from progressing without supplying the necessary information. The addEmployee function processes the employee data, configures delete and rename buttons to respond to relevant events, and generates a new employee entry based on the provided particulars. The rename button prompts the user to input a new name and updates the respective record accordingly, whereas the delete button simply removes the employee's entry from the employee database.
Conclusion:
A well-functioning Employee Database Management System (DBMS) has been developed successfully. In addition to incorporating HTML, CSS, and JavaScript for presenting and managing employee data, the system has implemented fundamental functionalities. Enhancements can be made to elevate the system further by including features such as integrated data validations, record editing capabilities, free text search and filtering options, and database access. Initially, you may start with a generic EDMS and then customize it to meet the specific needs of your organization.
