DATABASE MANAGEMENT CASE STUDY
TOPIC:“COLLEGEPLACEMENTMANAGEMENT SYSTEM”
Department of Computer Science
C. V. RAMAN GLOBAL UNIVERSITY,
BHUBANESWAR

INTRODUCTION
• Manual Training and Placement which is done at various colleges is by human intervention due to which there is a
maximum chance of errors. The major problem is searching and updating of the student data. Placement officers
have to manage the student’s profile and their documents. Placement Officer has to collect the information of
various companies who comes for recruitment. They have to arrange profiles of students according to various
streams and notify them each time according to company requirements. Placement officers submit the information
of students and if any changes or updates are required in the profile of any student, it has to be done manually. This
process is so difficult and tedious when the number of users increases. This is tedious and time consuming. Chances
of missing data are also possible. It is also difficult for collecting, managing, and updating student data as the
number of students increases. ’Placement Management System’ like many other placement management web sites,
provides information on placement providers and the placements and also keeps up to date information of all
students. It is a platform where students can view and assess their opportunities. The system will be having
different types of accounts for different types of users such as Admin, Student, HODs, and tutor. A profile for each
student is created with the necessary credentials for the portal. The system uses Oracle 10g for database
management and will sort the data of the student based on eligibility criteria demanded by the respective
companies and a list of eligible candidates will be prepared and they can choose if they are interested to attend that
particular drive or test. Based on this a final data-set is created and the interested candidates will be registered
automatically by the system. This way it reduces the work of college staff or faculty from the problems caused by
human error and wastage of time doing all processes manually.

Abstract of the Project College Placement
Management System:
From a student’s perspective, placements can bring a wide range of benefits and
opportunities. Training and management of placement is a crucial part of an educational
institution in which most of the work is done manually. Manual system in the colleges
requires a lot of manpower and time. With this project we aim to develop a web portal to
solve this issue. The project is aimed at developing an application for the placement
department of the college. The system is an application which will be accessed and
effectively used throughout the organization with proper login enabled. It can also be used
as an application for the Placement Officers in the college to manage the student
information about placement thus reducing the manual work and consumes less paperwork.
The system also provides the facility of viewing the personal and academic information of
the student. The system gets the requested list of candidates for the companies who would
like to recruit the people according to their eligibility criteria. Laravel framework is used to
facilitate the process of making the program.

Objective of Project on College Placement
Management System:
4
• The main objective of the placement management system is to reduce
manual work and time. It is difficult and time-consuming to collect all
the details from each student. To avoid this problem, we have planned to
develop a web-based placement management system.
• Easy to find out the list of eligible students attending the drives
• It manages the details of student records, placement training, different
placements happening in and out of the college.
• Saves the time of placement officer and faculties.
• Reduces the manual works.
This system makes student information more secure.

Requirement Analysis are as follows:

Problem Statement:
6
A placement cell contains the details of all the students studying in that organization. A
student is identified by different attributes like Student_regdno, Student_name,
Student_branch,Student_cgpa, Student_phone, Student_Email . A student can be placed in
many companies as per the requirements set by the company. Similarly a company have
many attributes like C_Id,C_Name,Cgpa,C_location. A student gets placed in the company
with the help of the placement cell which have details of both the student and the company.
We can get the details of every student placed in the company.
Existing System: -
 In colleges the records were stored in excel sheets hence sorting the data was always a
problem. The excel sheets are also less advanced. Hence sorting and searching problem
arises. Updates records is another tedious task.
 Another problem student faces are that they are not made aware of the training and
placement activity held in their intuitions hence there might have been a loss of
opportunities. The best solution here is to computerize the current environment.

Proposed System: -
 With the growth of technology, it is easy for the students as well as the companies
to get the information of newer placement programs.
 And this System also helps the placement cell to keep track of the data of the
students and the recruiting companies.
This System uses SQL (Oracle 10g) for Database management and will sort the
data of student based on eligibility criteria demanded by the respective
companies.

Normalization:
Normalization is the process of reorganizing data in a database so that it meets
two basic requirements: There is no redundancy of data, all data is stored in
only one place. Data dependencies are logical,all related data items are stored
together.
Tables in database are designed to use third normal form (3NF), AS we know
that to use third normal form our table must satisfy the requirement of first
normal form ((1NF) and second normal form (2NF).Most of the tables in
database have been designed to keep optimization in mind. We use
normalization to remove update, delete & insert anomalies.

1nf :
By implementing First Normal formal we have to check that there should be no
multiple values against any field of a table and we have to create a separate
table for each set of related data with unique primary key.
 A table is referred to as being in its First Normal Form if atomicity of the table
is 1.
 Here, atomicity states that a single cell cannot hold multiple values. It must
hold only a single-valued attribute.
 The First normal form disallows the multi-valued attribute, composite
attribute, and their combinations.

2nf:
For 2nd Normal form the non key attributes should be fully dependent on
composite primary key, partial dependency is not allowed. First we
created two tables from above tables to associate with repeating group of
data and relate them with foreign key.
The first condition for the table to be in Second Normal Form is that the
table has to be in First Normal Form. The table should not possess partial
dependency. The partial dependency here means the proper subset of
the candidate key should give a non-prime attribute.

2 NF

Student Name C_ID
Ram Singh 104
Sanjeev Kumar 102
Ram Singh 105
Ritika Mishra 106
Student name P_ID
Ram Singh 6
Sanjeev Kumar 3
Ritika Mishra 18
As per the second normal form definition,
our enrollment table above isn’t in the
second normal form. To achieve the same
(1NF to 2NF), we can rather break it into 2
tables:
Here the second column is unique and it indicates the C_ID for the student.
Clearly, the C_ID is unique. Now, we can attach each of these C_ID with
P_ID.

2 NF
29
C_ID P_ID
104 6
102 3
105 6
106 18
These 2 tables together provide us with the exact same information as
our original table.
