COURSE DESCRIPTION

This assignment on DBMS is designed for the students of B.Sc.

(Computer Application), IV-Semester to learn the concepts of DBMS.

DBMS is actually system software that enables a user to create and

maintain a database. It facilitates the process of defining,

constructing, manipulating and sharing databases among various

users.

There are several DBMS in the market, among these Oracle,

MySQL are most popular and widely used. Oracle provides a free

version namely Oracle Express edition for the student and

independent developers for performing data base related tasks.

MySQL is an open source DBMS maintained by Oracle. Student can

use Oracle/MySQL for this assignment.

CONTENT

This Lab assignment course is designed to help students to

create database and apply PL/SQL to manipulate the database.

Several live scenarios have been included in the assignment to

design E-R Diagram and subsequently create database. Students are

supposed to write queries for creating, retrieving and manipulating

the database. This course is indented to develop a deep

understanding of various query languages such as DDL, DCL, DML, PL

OBJECTIVES

After completing this Lab assignment, the students should be able to:

Design databases from an ER diagram.

Page 4: Lab Manual B.Sc. (CA) Manual Design Committee: Prof. Mohammad Ubaidullah Bokhari Dr. Arman Rasool Faridi Dr. Faisal Anwar Dr. Aasim Zafar (Convener) Editor: Dr. Aasim Zafar Design

Create a full fledge database for any system.

Write different types of SQL queries.

Write PL/SQL block, Cursors, Triggers, Procedures and

functions.

OUTCOMES

After completing this course, the students would be able to:

Understand the concept of relational database management

system.

Comprehend query languages and their usage.

The students must get the completed weekly

activities/assignments checked and signed by the concerned

teachers in the Lab in the immediate succeeding week. Failing

which the activities/assignments for that week will be treated

as incomplete.

Examination.

The students need to submit the following two deliverables for

each exercise duly signed by the Teacher:

ER Diagram (Only for the questions 1,2,3,6, 7,8,9,10 and 11)

SQL query with output

Each question will be evaluated on a scale of 10 points, 4 for E-

R Diagram (where applicable) and 6/10 for queries.

The students need to ensure that each question is assessed and

signed by the Teacher in the week/time.

Late submission would not be accepted after the due date.

PROBLEMS

1# Consider a CONFERENCE_REVIEW database in which researchers submit

their research papers for consideration. Reviews by reviewers are recorded

for use in the paper selection process. The database system caters primarily

to reviewers who record answers to evaluation questions for each paper they

review and make recommendations regarding whether to accept or reject the

paper. The data requirements are summarized as follows:

a) Authors of papers are uniquely identified by e-mail id. First and last

names are also recorded.

b) Each paper is assigned a unique identifier by the system and is described

by a title, abstract, and the name of the electronic file containing the

paper.

c) A paper may have multiple authors, but one of the authors is designated

as the contact author.

d) Reviewers of papers are uniquely identified by e-mail address. Each

reviewer‟s first name, last name, phone number, affiliation, and topics of

interest are also recorded.

WEEK #1

Page 8: Lab Manual B.Sc. (CA) Manual Design Committee: Prof. Mohammad Ubaidullah Bokhari Dr. Arman Rasool Faridi Dr. Faisal Anwar Dr. Aasim Zafar (Convener) Editor: Dr. Aasim Zafar Design

e) Each paper is assigned between two and four reviewers. A reviewer rates

each paper assigned to him or her on a scale of 1 to 10 in four categories:

technical merit, readability, originality, and relevance to the conference.

Finally, each reviewer provides an overall recommendation regarding each

paper.

f) Each review contains two types of written comments: one to be seen by

the review committee only and the other as feedback to the author(s).

Design ER diagram and construct database for the above. Give logical

reasoning for the database design.
