1.INTRODUCTION

1.1 About Project:

The security of the data is provided through authenticated users, one can viewand update the data upto their access permissions only. The information regarding to tasks is

provided through syntaxes and sample programs about that lab. Faculty is able to post and update marks of students. All the users of automation of labtasks can give and view the feedback and faculty is able to provide notices related to tasks,like date of task submission, dates of lab examinations. The students are provided

permissions to view the notices only. Once the student logged into the lab automatically

his/her attendance marks will be posted. Administrator maintains database and solves if any technical problems occurred byusing technologies like servlets, sps using tomcat server and can retrieve the data fromdatabase using oracle !"g.

2. PROJECT ANALYSIS

2.1 Purpose of the project# Automation of lab tasks minimi$es the difficulties in maintaining the studentsdatabase .%eport genartion by faculty is performed easily by faculty.A very brief guidance is

provided through syntaxes and sample programms to the students. &ecurity is provided to therecords by only allowing authenticated users to access the system.

'.' Exst!" s#ste$:!( Faculty maintains the students) data manually in task evolution sheet.'( The time duration of report generation is high, because of the operations on

student data are performed manually by the faculty.*( +ore guidance should be provided by faculty to the students about the specific

task, if they have not that much of knowledge about that task, so that they can)t

utili$e the practice session completely( The security to the task evolution sheet is low, so that unauthori$ed will be able to

view and update the marks.

The time duration of report generation is high, because of the operations on

student data are performed manually by the faculty. +ore guidance should be provided byfaculty to the students about the specific task, if they have not that much of knowledge aboutthat task, so that they can)t utili$e the practice session completely

The security to the task evolution sheet is low, so that unauthori$ed will be ableto view and update the marks.
