This document describes a grade management system that was designed and implemented by students at IIT Mandi. It uses SNMP protocol for data access and is divided into four parts - an API built in Python, Net-SNMP, an SNMP server, and a MySQL database. The system is designed with a client-server architecture and allows faculty, students, and teaching assistants to access and manage course and student grade data.

- 3. 1 PREAMBLE 1 Preamble 1.1 Project Overview Project aims at providing a Grade management system to Faculty, Students and Teaching Assistants. This project takes the advantage of SNMP protocol. The motive behind this project is to understand the Access control provided by V3 of SNMP and how SNMP can be used to manage data. In addition to these this project also helped in understanding Application Programing Interface and how API can be created for building applications. 1.2 Software Overview The software is divided into 4 parts. They are 1. API 2. Net-SNMP 3. SNMP Server 4. Database Out of these Net-SNMP has been used as it is. API is written in Python. Conguration changes were done in SNMP Server and Mysql is used for storing data which is connected to SNMP Server through Perl. 1.3 Purpose This document is intended for Developers who want to use this API either to build an application for grade management, people are looking for a way to use SNMP for managing their data. It explains the software design and software architecture. 1.4 Requirements The software takes leverage of the following softwares: 1. Net-SNMP 2. MySQL 3. Perl 4. Python The software is divided into 3 block which can function on 3 dierent machines. They are: 1. Net-SNMP Client Grade Management System, IIT Mandi 3
- 4. 3 DESIGN 2. SNMP Server 3. MySQL Server 2 User Interface Specications This software is an API built over Net-SNMP. API is written in Python and it provides classes and functions for accessing data over SNMP. Name of the packege is 'grading'. This package can be congured to access 3 Design The software is designed as a client-server architecture. There are 3 blocks which work as client server/clientserver. 3.1 Modular Decomposition Give the break-up of your software into logical modules, accompanied by a gure. Show control ow with broken lines, data ow with solid lines. Grade Management System, IIT Mandi 4
