INTRODUCTION TO COMPUTER LAB MANAGEMENT SYSTEM

"Computer lab management system can have several meanings: it can refer to software like

Foolproof or Fortres which "locks down" the computer and only grants users access to limited

software features. In the context of this article, however, "computer lab management software"

refers to progams used by a teacher in the course of a lesson to maintain student attention andenhance instructional delivery. Screen sharing is a typical feature of lab management software,

allowing the teacher's computer screen or another student's screen to be shared with every othercomputer in the lab. Effective use of computer lab management software can make a

tremendous, positive difference when teachers use a computer lab for instruction.

PURPOSE OF COMPUTER LAB MANAGEMENT SYSTEM

To acquaint staff with basic lab procedures and management

To promote the integration of technology into the curriculum

To encourage staff to use computer labs effectively.

Advanced Features

Some management programs offer additional features with wonderful instructional

benefits for classroom teachers and students.

Shut down or restart computers: It can be time consuming at the end of the day to shut

down all the computers in a lab or classroom, or to restart them before the next class.

Some programs offer the ability to shut down or restart an entire lab simultaneously with

a few mouse clicks on the instructor computer. Installed Network Interface Cards (NICs)in each computer must support this feature for it to work.

Transfer a file to all student computers: If a school file server is available and a

"shared folder" has been created allowing student as well as teacher access, files for a

particular lesson can be opened from the network. Some lab management programs allowfor the distribution of files directly to the hard drive of every computer in the lab,

however, and some can even retrieve modified and saved files from the studentcomputers to the instructor computer at the end of class.


4/9

Chat: While some teachers may think this feature is superfluous and unneeded, chatcapability included with lab management software can be invaluable for a variety of

reasons. First, most students love to chat on their computers: typing text messages to

each other like they would in an online chat room. A major difference between an onlinechatroom and a chat environment provided by a lab management software program is

that the participants are controlled: only those students physically in the room canparticipate in the chat. As a reward for staying on task or completing a lesson, students

can be given five minutes of chat time at the end of the period. Students desperately needguidance and instruction on what is appropriate and safe to disclose in an online chat

environment, so in addition to motivating students, chat sessions can also provide them

with invaluable digital safety skills.

NORMALIZATION

It is a technique for designing relational database tables to minimize duplication of information

and thus increasing the logical consistency.It represents the database design in a normal form.It

represents a good datao base design.It is used to eliminate various anomalies and inconsistencies.

Normalization basically depends on the concept of dependencies as functional,partial,transitive

or multi-valued dependency.

1NORMAL FORM

A relation is said to be in 1st normal form if:

all the primary key attributes are defined.

There is no repeating group in the table.

All attributes are depend on primary key.

=>As here is no repeating group present in the table so no need to find first normal form As it is

already in first normal form.

2 NORMAL FORM


8/9

A relation is said to be in 2nd normal form if:-

The relation is in first normal form.

Every non key attributes which do not form primary key should be fully functionally

dependent on the primary key.

Before normalization:-
