PHP project using AJAX, Bootstrap and MySQL- Internal Document Management

Internal document management is the basic need of any organization. There can be countless notices, information reports and memos that must be shared with employees of an organization. Internal Document Management System is a PHP project using AJAX, Bootstrap and MySQL. It is developed to give a brief insight into the activities related to this function. This Web Application is a simple implementation offering interface for employees as user and Administrators.

User Dashboard

The user, in order to upload a report or document, must first be assigned a user id and password by the administrator. Once a user logs on into the system, the user dashboard displays the option to update a new report or view the already uploaded reports.

When an admin logs on with her credentials, she is presented with dashboard to perform all the tasks related to an administrator.  The administrator can add or modify a department, a committee or a user. For modification of an existing data Bootstrap Modal forms are used that displays the selected record in a modal form and data in table is updated by reentering values in this form.
