Employee Database Management System using HTML CSS and JavaScript

Introduction:

In this article, we are going to employ HTML, CSS, and JavaScript to create the Employees Database Management System, and its implementation is going to be shown in the examples.

The target of this article is to use three web programming languages: HTML, CSS and JavaScript to design Employee Database Management System (EDMS). JavaScript gives dynamicity to the site, CSS maintains visual stability, and HTML provides underlying structure. Here, JavaScript will be used to develop a management system for employee's database.

The purpose of this employments supervising system is improvement of output performance, simplification of administrative wages and affording companies with an approachable way to do personnel management.

Indeed, along with handling employee data, businesses of all sizes now must stay updated in the digital age. The application of an Employee Database Management System (EDMS) can improve operational efficiency and decision-making through the optimization of procedures such as storing, organizing, and retrieval of employee related data. By that, we will have online applications that are easy to use and they handle records of employees really fast and seamlessly.

How to create Employee Database Management System using HTML CSS and JavaScript:

Creating an Employee Database Management System (EDMS) using HTML, CSS, and JavaScript can be a rewarding project. Here's a breakdown of how you could approach it:

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 (JavaScript):

  • since this is a front-end project we will use JavaScript to simulate data storage. You can store employee records as objects within an array or use local Storage to persist data locally in the user's browser.
  • Define functions to handle CRUD (Create, Read, Update, and Delete) operations on the employee data.

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.

Displaying Data (JavaScript):

  • Write the JavaScript functions that we will see to it that HTML elements are dynamically generated equivalent to the employee records to be displayed in the user interface.
  • Apply DOM manipulation approaches to change the interface after a user input, e.g., making additions, re-editing or deleting employees' records.

Validation (JavaScript):

  • To validate the data users enter, it is best to implement validation checks on input fields while they're editing or adding new employee records. State whether the field ensuring the existence of name, email, phone number, and the other section exists.
  • It provides feedback in case of any validation error, outlining the details that ought to be corrected.

Interaction (JavaScript):

  • Make the interface enabled for interaction through event listeners on buttons, forms, and inputs.
  • Catch up with the user actions like clicks, form inputs, and keyup events, etc to strengthen the code flow in the app.

Testing and Debugging:

  • Test the application thoroughly and carefully to provide an assurance that all the features are clearly meeting their purpose and working, and to also ascertain that there are no bugs or errors.
  • Make browser developer tool your best friend when debugging and fixing issues that might arise during test preparation.

Accessibility and Usability:

  • Ensure that you design your website to suit people with disabilities by meeting web accessibility standards.
  • Provide your users with a seamless experience by making the interface natural and zeroing-in on the navigation issues.

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

The framework of our Employee Data Management System is built on top of HTML (HyperText Markup Language). We'll outline the components required to collect and present employee data.

HTML Code:

Explanation:

The main structure of a simplified Employee Database Management System's HTML document is displayed in the above sample of code. Let's explain it:

A web page with HTML code for an employee management system is built with the following: It is equipped with a form which is for adding new employee details. It requests the information such as the name, department, address, salary, email address, and telephone number. In order to onboard new employees, it is required to fill out the form and submit the button. Also, there is a box to show the employees' list. Moreover, the website implements linkages to additional script.js and styles.css javaScript files into its functions and to improve appearance. In a nutshell, such a snippet generates an introductory user interface for governing employee information.

1.2 Using CSS for Style

Cascading Style Sheets, or CSS, improve the EDMS UI's appearance and design. In order to increase readability and usefulness, we'll establish styles.

CSS Code:

Explanation:

This code snippet is a CSS stylesheet containing styling rules for elements within an HTML document. Let's discuss it:
Here follows a line of CSS code involving a border-box model for accurate scaling and resetting both the margins and the paddings for all items. It makes use of a selected font and background color for the body. The elements of the container be properly divided in this card,alonge with the width, margin, padding, border radius, and box-shadow. The font is sorted out with clear whitespace and placed in the centermost area of the documents. Regular shapes, such as box shadows, padding, and background colors, are styled in a consistent way. However, these buttons consist ofa commonn background color, padding, and the transition effect when hovered. The other parts, namely, the margins, padding, background color, border radius, and box shadow of the list elements, are also chosen. Along with the buttons for renaming and removing, their hovering effects are also the same.

2. Using JavaScript to Implement Functionality:

Adding Employee Data, JavaScript allows for dynamic interaction with the EDMS, which enables us to save employee information, collect user input, and change the user interface (UI) as needed.

JS Code:

Output:

This is the user interface for adding employees' details to the EDMS:

This is the UI of the list of employees after adding the details of employees

Explanation:

This snippet of code uses JavaScript logic to manage form submissions and dynamically add employee information to a webpage. Let's analyze:

In its concealed direction, this little piece of JavaScript code is used to configure an event listener to be run when the employee form is submitted. It obtains data about a form, checks if all the required fields are filled in, and also prevents the normal behavior of a form submission. If yes, the input field is cleared before using the addEmployee method, which is associated with the mentioned data. If the user fails to do so, the user is not allowed to move forward without providing the correct data. The addEmployee function takes the employee record and sets up delete and renames buttons to listen to the applicable events, and creates a new employee record with the given details. The rename button expects you to type in a new name and changes that record if you do, but the delete button simply erases the employee's entry from the employee records.

Employee Database Management System using HTML CSS and JavaScript

Conclusion:

We designed an employee Database Management System (DBMS) that works perfectly. The system also fully integrates HTML, CSS, and JavaScript for displaying and storing employee information. But it is just some basic steps. The system could be made even superior by integrated data validations, record editing, free text searches and filters, and access to a database. Initially, you might have a generalized EDMS, which you will focus on fine-tuning to accommodate your organization's special requirements.
