E-Tendering - Computer Science & Engg. - Miniproject

Computer Science & Engineering - Miniproject
Electronic Tendering (E-Tendering)
ASP.Net - SQL Server - C#
Abstract:
 
Electronic Tendering is carrying out the traditional tendering process in an electronic form, using the internet. E-Tendering (Electronic Tendering System) is an online service. It provide everyone involved in the Business industry, especially Suppliers and companies, with an efficient, secure, simple and cost-effective tools to facilitate the best use of Tender Information and to enhance our business outcomes - anywhere, anytime.
It is created with following missions in mind.
  • To provide rapid calling of Tender and to reach a huge number of Suppliers, and receive large number of bids from suppliers from anywhere at any time.  All the Tender information is at a single button click.
  • It also organizes all of the Tender history and bid information that they typically provide to the website at the time of service.
  • It also allows the Suppliers to know whether the Tender submitted selected or not in a few seconds.

The proposed System is an online service system. Here the companies who have a work or need some good, create a Tender online. The company is a registered User of the portal. He can manage the tender using the username and password. The company can create more than one tender at a time. Anybody who visit the site can see the tender, if supplier satisfy with the tender create a bid to the tender. Applying to the tender is a simple process. Supplier login into the site and create a bid in online. The bid reach the company in a second. The company can evaluate different bids and release the contract to the appropriate supplier Using E-Tendering the users can:
  • Raise Indents as per the requirement ·
  • Approve indents online
  • Sell Tenders
  • Receive Bids
  • Award Contract / PO
  • Evaluate Tenders
  • Create and publish NIT
  • Includes a variety of off techniques such as RFPs, quotes, auctions and reverse auctions.

Using E-Tendering, the suppliers can
  • Receive notification of the relevant tenders
  • Purchase tenders document
  • Submit Bids Online
  • Track the status of their bids

The tenders are published by the companies who are in demand of the goods. Using the E-Tendering System, the users of the participating companies will:
  • Raise indents as per the requirements
  • Approve Indents online
  • Create Tender
  • Approve Tender and
  • Publish Tender online

The users who registered as suppliers of this system will:
  • Receive tender notification
  • Submit Tenders

The system will auto evaluate the bids of the suppliers and guide the user to select its apt supplier.

The system can be developed using ASP.NET and MSSQL Server or any other web application developer.

Content Management System - Miniproject - Computer Science & Engineering


Computer Science & Engineering - Miniproject  
CONTENT MANAGEMENT SYSTEM
php - mysql
Abstract:
Content management systems nowadays are used to manage complex publications far more often than some years ago. The basic principles are the separation of structure, content and presentation, an exactly defined workflow management and the management of content in the form of small units, so called assets. This leads to improved quality, better reusability and reduced costs.
The Web Content Management System (Web CMS) is content management system software, implemented as a Web application, for creating and managing HTML content. It is used to manage and control a large, dynamic collection of Web material (HTML documents and their associated images). The Web CMS facilitates content creation, content control, editing, and many essential Web maintenance functions.
A content management system (CMS) is a system providing a collection of procedures used to manage work flow in a collaborative environment. These procedures can be manual or computer-based. The procedures are designed to do the following:
  •  Allow a large number of people to contribute and to share stored data
  •  Control access to data, based on user roles (defining which information users or user groups can view, edit, publish, etc.)
  •  Aid in easy storage and retrieval of data
  •  Control of data validity and compliance
  •  Reduce repetitive duplicate input
  • Improve the ease of report writing
  • Improve communication between users

Network Monitoring and Controlling System - Miniproject - Computer Science & Engineering - Java


Computer Science & Engineering - Miniproject 
Networking Monitoring and Controlling System
Java - NetBeans 



ABSTRACT

Network Monitoring and Controlling Software are exclusively designed for monitoring and controlling systems/users present in a Local Area Network of an organization. NMCS is a client server based system and utilizes the possibilities of Remote Method Invocation (RMI). NMCS is designed in such a way that the administrator can monitor  and control  the systems present in the network. There are two levels of privileges viz. administrator and user.. In the proposed system each user is provided with a unique Id and password. The system maintains a database of this information’s. The user can change their password, if required.
The PC Controlling module displays the remote PC's desktop on the screen of your local PC just like a surveillance camera. The remote connection could be established on LAN. In this module the administrator can view all the PC’s in his Office with details of the user logged in. The administrator and users/staffs can chat or send private messages to a particular staff. Similarly an user can send messages to another user with the administrators permission Remote Power Management allows you to ON, shutdown and restart remote computers. Administrator can send a common message like meeting or asking to logoff the system for some particular reason, something like that to all Online Users or Administrator can select particular users and send the common message to them.

Student Management System Using SMS - Miniproject - Computer Science & Engineering - Java - NetBeans

Computer Science & Engineering - Miniproject
Student Management System Using SMS
Java - MySQL - NetBeans



ABSTRACT
The Student Management System using SMS is designed to automate the  Student Management System using text messages. It can handle details of a student such as marks, attendance, etc. The system is based on the text messages sent from a GSM mobile phone. The proposed system is to computerize the various processes of the student management system by sending sms to the server from any remote location. The system has two types of accessing modes, the administrator and the user. The administrator manages the student management system. The user access the data in the system using sms. The main objective is to automate the easy storing & retrieval of data through text messages by an authenticated person. Data regarding the users such as personal details, academic details, complaints, etc. are collected and maintained in the student management system for secured process. The project uses JAVA as front-end and mysql as back end in Windows XP platform. NetBeans IDE is used for the development of the system.

The main features includes:

  • Registration of new students
  • Information of marks, attendance, etc.
  • Complaint Registration/status
  • Notification to parents.
  • Result publishing, hall tickets.
  • Notification from students,teachers, principal, or other staff...
  • Fee details
  • Other due status notification
  • …
