AIM

The aim of this course as we perceived was to get ourselves acquainted

with all the general understandings of how a database actually functions.

Through a series of steps starting from the very basic to a relatively higher

and complex models, we tried to gradually develop our understanding of

the course by doing a case study which was assigned to us. The case study

which we were supposed to work upon was to analyze the role of database

management in the system of UID (Aadhar Card) in our country.

ABSTRACT

Through surveys, questionnaires, interviews and various other modes of

interpretations, we laid out a proper plan involving all possible aspects of

database management in the concern of the aadhar card system.

Accordingly, we integrated these things to our course structure and

analyzed them on various technical concepts, all of which helped us in

creating our database on the system of UID which would be discussed

further in great detail.

Specification

for Aadhar Card

1.1 Problem Description

1.1.1 INTRODUCTION AND OVERVIEW

1. UID or Unique Identification is an initiative initiated by the UIDAI to empower the residents of our nation by providing them a platform to authenticate at any time at any place. 2. UID basically is a 12 digit unique number for every individual in our nation including the newborns and children. On the basis of demographic and biometric data, the UIDAI initiative aims at delivering aadhar card numbers to over 60 crore residents of the country by 2014. 3. To add to the perspective of integrity and nation building, the UIDAI also collaborates with top notch partners across the country to set-up infrastructure which provides convenience to residents. The residents then can authenticate their digital identity. 4. The procedures and measures taken by the UIDAI are robust enough to eliminate the fake IDs and duplicity. Henceforth, UIDs can be verified and authenticated in a very cost effective way. Associated References :

1.1.2 MAIN OBJECTIVE OF CASE STUDY : a) PRIMARY OBJECTIVES: The main objective of our case study is to create a database of the people who are the beneficiaries of the Aaadhar Card System. This database would include the biometric data, the demographic data of the people which would be unique for each and every Indian and would help us authenticate our identifications in a better manner. b) ALTERNATE OBJECTIVES : Alternative uses of aadhaar card can be as follows : 1. For opening Bank Accounts, getting pipeline connections, mobile phone connections. 2. While applying for passports, aaadhar cards can prove to be of great significance. 3. Obviously, it will also lead to employment generation. Departments which would be set up for delivering aadhaar cards and carrying out the process of generating UIDs would provide a lot of employment. 4. Security of Nation : The issues of illegal migrants can be heeded and curbed by the concept of UIDs. This is a problem which has troubled the central government a lot. 5. Flexibility on know your resident (KYR) and electronic paperless KYC enabled. Aadhaar card is by far, the simplest identity proof.

1.1.3 CASE STUDY STORY ( SUMMARY OF RESEARCH ) :

1. India is a huge country with over 1.2 billion of population. As the data in the link 1 suggests, as of 2013, less than 50 million Indians held passports, around 100 million people had PAN cards and just 20 crore people had driving licenses. 2. A large section of our society still has no ID proof. So to resolve this problem of lack of ID proofs throughout the nation, the objective of UID came into picture. 3.The objective of our case study is to study these issues and prepare a database so as to learn more about the prevailing problems. 4.Whenever we migrate to any city, to get a new phone connection, gas pipeline connection, etc. we need an ID proof and since a large section hold no ID, this Aadhar card system is sanctioned by the govt. for all Indians irrespective of caste, creed, societal stature, etc. 5.The poor didn't had the resources like IDs which barred them from availing services like ration cards, bank accounts, etc. So accrediting the poor section is an important specification of development of aadhaar card.

1.1.4 MODULES A sample of an aadhar card

Different kinds of data modules are required for generating a UID : 1. DEMOGRAPHIC DATA : a) Compulsory data : Which includes name, age/DOB, gender. It also includes the address of residents. b) Conditional Data : Which includes guardian/parent details. c) Optional Data: Which includes phone no. and email address. 2. BIOMETRIC DATA : a) Resident's photograph. b) Resident's finger prints. c) Resident's iris. 3. PROCESS : A) Representation from agencies, academic and industry. B) Standardization on modalities and data formats.

1.1.5 PROCEDURE FOR APPLYING ONLINE/OFFLINE :

All the activities regarding the accomplishment of AADHAAR are done by the planning commission of the Unique Identification Authority of India. The word AADHAAR could be described as the foundation or support, There are few guidelines for applying for Aadhar card. 1. Enrolment for aadhar cards is circulated in the local media and persons have to register there. They will be called for iris of two eyes and biometric impressions of all the fingers are taken and the aadhar card will be issued with in 30 days of time. 2. There is not necessary for the whole family to attend at one time and at one place. Individuals can enrol at any place and time. 3. You can apply through online for Aadhar card. The Government has started issue of Aadhaar Smart Cards for the people online. Download application forms available in English. To proceed with online registration, you need to enter your Ration Card No and get the details before entering family members particulars. 4. If you have downloaded the Aadhaar application for offline submission, you may require to attach these documents or certificates along with printed application form.

1.2 REQUIREMENTS COLLECTION

1.2.1 Our case study basically identifies different types of users and accordingly categorizes

them into categories and relationships which helps us in analyzing about the people who

have enrolled the aadhar card. In this case study, basically we perform the role of a company

or an agency who acts as a middlemen responsible for generating aadhar card for the

citizens of the country.

1.1 User Characteristics ( USER CATEGORIES )

A) Citizen : Uses the fingerprint bio-metric for recognition. He needs to provide with

personal details and his fingerprint images.

B) Operator: The operator is one who enters the demographic details of the citizen

into the computer.

C) Employee : As would be shown in the ER Diagram further, an employee can also

be a category of a user. People can work as an employee and manage work.

1.2 Assumptions :

Both Aadhaar and NPR are based on the unscientific and questionable assumption that there

are parts of human body likes fingerprint, iris, voice etc that does not age, wither and decay

with the passage of time.

Those who support Aadhaar and NPR seem to display unscientific temper by implication. If

in case scanned image of fingerprint distorted, user can again scan their fingerprint.

1.3 FUNCTIONALITIES

1.3.1 Registration/ Enrollments : We need to design a system which would give us a

separate information about the users who have registered for the aadhar card and have got

their registrations successful where as those who have registered for the aadhar and are still

witnessing unsuccessful registrations would be identifies separately. The person can go to

any authorized aadhar enrollment centre in India with his/her ID proof. This makes it easier

to identify the users into separate categories thus making it a functionality.

1.3.2 UPDATION process : Keeping in mind that the system of aadhar card is too hefty

and can be inaccurate at times, sometimes wrong details are entered into the aadhar card

database for a given person, the person is given the opportunity by the UIDAI to UPDATE

his/her database either OFFLINE/ONLINE.

A) Family tree : If there's a new entrant into a family, or if a person in a family

November


11 | P a g e

dies and family tree gets altered, the system updates itself automatically. If a woman gets

married, her surname changes, she becomes a part of another family, then she

might have kids. All of this data gets updated into the aadhar card database

1.3.3. Aadhar Card Status : Separate portal for checking out the status of aadhar card has

been put up by the UIDAI. By this means, the person can track his/her processing of the

aadhar card. Accordingly, the person gets notified if the processing is successful, the

aadhar card gets generated, if not, either the generation is under processing or rejected

due to lack of documents or variety of other reasons.

1.4 MODULE CONSTRAINTS

1.4.1 Enrollment Issues: a) Many people who enrolled for aadhar card during the first

phase of enrollment faced the issue of unavailability of aadhar cards. The aadhar card details

were either lost or unusable due to an 'encryption error' . In such cases the enrollment

module on the UIDAI portal ( http://aadharcarduid.com/aadhaar-card-not-received ) enable

the user to re-enroll for the aadhar card under few conditions :

1 ) If the status on their aadhar card says 'Rejected'.

2 ) If the status shows 'not found'.

3) If the status says, cannot be processed due to 'technical reasons'.

b) If the aadhar card status shows rejected due to lack of

availability of documents, the user can still apply for aadhar card even

though there's an enrollment issue. Even if someone in a family does not have individual

valid documents, the resident can still enrol if his/her name exists in family entitlement

document.

In this case the Head of Family in entitlement document needs to be

enrolled first with valid PoI & PoA document.

The head of the household can then introduce other members in the family

while they are enrolling. http://uidai.gov.in/how-to-enroll.html )

1.4.2 DATA UPDATION MODULE : Date of Birth, Residence address, name and gender,

your contact number or any other information which is present in your aadhaar card can be

easily changed if it’s incorrect. Two methods to update data are :

1) Online Method : To update the data online, we need to visit the UIDAI website and use

your mobile number for logging in. You will receive an OTP number on your cellphone

http://aadharcarduid.com/aadhaar-card-not-received

http://uidai.gov.in/how-to-enroll.html

which will help you to proceed further.

1.1 ) Log in.

1.2 ) Upload Documents

1.3 ) Select BPO service provider and submit request.

2) Offline Method :

2.1 ) Download the correction form from the UIDAI website.

2.2) Fill the form with self attested photocopies and give a working mobile number.

2.3) Post the form in an envelope.

Reference : http://aadhaarcarduid.org/how-to-update-change-your-aadhar-details/

1.4.3) CURRENT STATUS : To check the status of aadhar card, we need to visit the portal,

give the enrollment ID and enter the security code.

By this way, we can track the status of our aadhar card.

1.5.2 Questionnaire/Interviews :

Keeping in mind the advantages of the UID system and the complexities it can cause, we prepared a

questionnaire for a general public to take a note about their awareness of the UID and there

suggestions, advises or criticism on the same. We tried to include a variety of questions in the

questionnaire, questions ranging from whether they had an Aadhar Card to whether they were about

schemes like KYC(Know Your Client) which are triggered by UID. Questions we asked are divided

into various subtopics below :

5.1 Are you aware about the system of UID initiated by the government of India?

This was the most basic question which demanded to be asked. It's very much necessary for people

to be aware about the system of UID in order to avail benefits from the same or criticize it.

Awareness about UID is something which is needed even if you don't support the concept of Aadhar

Card. Maybe, you can suggest changes. So we felt the need to ask this question.

5.2 Do you have a UID? If yes, are you aware about the benefits of UID?

In today's India, there's quite a possibility that a person might possess an Aadhar Card and still be

unaware about the benefits. It happens a lot. Possibly because the government and the UIDAI

themselves haven't laid out the benefits an Aadhar Card can hold for a citizen in a transparent

manner on a national platform.

5.3 Do you think that the system of UID is indirectly a security breach in the lives of

concerned citizens?

There are arguments which pop up in public forum like Aadhar Card infringes on our right to

fundamental privacy. Linking of the Aadhaar number with food security under the new Act, LPG

subsidy, the Employees’ Provident Fund and other direct transfer of benefits made enrolment under

the Aadhaar scheme mandatory, falsifying the government’s claim that it was voluntary. So this is

an essential argument over which we thought the views of a general public would be if great help.

November


14 | P a g e

5.4 What do you think are the alternative benefits of UID?

We wanted to check if people were aware of other benefits of UID apart from acting as an unique

ID. Benefits like the UID can help while getting a passport, while getting a gas connection, while

getting a telephone connection, a ration card, etc. So we asked this.

5.5 What are the improvements you suggest in the present system of Aadhar Card?

A general question to consider views from people about what changes if any they could or would

suggest in the current system of Aadhar Card(UID).

5.6 Are you aware about the KYC scheme by the government which is triggered by the UID system?

To distinguish the well aware class from a little bit unaware class, we asked this question. This

question was a bit too deep but we thought it was necessary to check out if few of them people were

literally aware about the KYC approach.

5.7 Do you think that the concept of UID would benefit those who migrate constantly from

one state to another and face difficulty getting a new pipeline connection, a new telephone

connection, etc.?

This question is actually a fact. By giving the fact that UIDs can benefit people who are into

constant migration to get pipeline connections, phone connections, etc. easily we wanted to see if

there are people who can disagree with a fact.

So we prepared a total of seven questions. We tried to include all about the domain of UID in this

survey form we prepared which helped us in preparing these seven to-the-point questions. We

received sufficient responses to analyse our survey in a more concrete manner. The responses are

discussed in the next section.

November


15 | P a g e

6.Observations:

We received a total of 53 responses to our survey form over a period of 3 days.

6.1 Are you aware about the system of UID initiated by the government of India?

Observation: Over 95% of people who took the survey were aware about the system of Aadhar Card

initiated by the UIDAI. Awareness on such a large scale is always a positive factor because it helps

you to identify and interpret things.

6.2 Do you have a UID? If yes, are you aware about the benefits of UID?

November


16 | P a g e

Observation : Approximately, about 20% of people didn't had aadhar cards. To much surprise, about

40 percent of those possessing aadhar cards weren't aware about the benefits of aadhar cards they

were holding where as 45 percent were aware about the benefits of aadhar and they also had one.

6.3 Do you think that the system of UID is indirectly a security breach in the lives of

concerned citizens?

As we told above, in the questionnaire section, this is much debated topic. Thus, we almost got an

equal number of votes to both the answers. Some people think that it's a security breach where as

some don't, fair enough.

6.4 What do you think are the alternative benefits of UID?

People had different answers like :

We can identify a person using their retina scan or their fingerprints.

A single card serves all purposes.

People won't be questioned for their authenticity.

Benefits in passports, ration, gas pipelines.

A unique number would lead to a better public distribution system.

Keeps a track of all the citizens so it can be advantageous for national security.

November


17 | P a g e

6.5 What are the improvements you suggest in the present system of Aadhar Card?

Some people suggested that Aadhar Card should be used as a voting card too. It'll then

be a huge benefit.

Inclusion of public libraries.

To keep a check of activities of citizens.

Expansion of this scheme to rural areas too.

It should be made a standard proof of identification and for other purposes.

6.6 Are you aware about the KYC scheme by the government which is triggered by the UID

system?

About 60 percent of people were unaware about the KYC approach implemented by our

government. This KYC(Know Your Citizen) approach can be triggered by UID. This question was

just to test the in depth awareness of a certain section of public regardless of whether they owned

aadhar cards or not.

6.7 Do you think that the concept of UID would benefit those who migrate constantly from

one state to another and face difficulty getting a new pipeline connection, a new telephone

connection, etc.?

one of these should be used as the basis for an entity

• Irrelevant: entities which exist in the problem domain but which are not part of

the intended system should also be discarded

• Vague: When considering words carefully it sometimes become clear that they do

not have a precise meaning and cannot be a basis for useful entity in the system

• General: Some words are too general

3. ALL IN ONE

In this section, ER To relational mapping the DDL Statements, constraints(Primary Key, foreign key, etc.), normalizing the entities and the relationships, everything has been done.

This section shows the functional dependencies, anomalies(update, insert and delete)

1. For citizen, a table named citizen with attributes ID, Name and Address passed as

parameters :

create table citizen(id int, citizen_name varchar, address varchar, Primary Key(id));

NORMALIZATION : Update anomaly : no update anomaly

DELETE and INSERT anomaly also won't affect the entity

THIS IS IN 1NF

For our convenience we have broken the table into,

citizen1(id,uid) AND

citizen2(id, citizen_name, address)

For 2NF, we check to remove all partial dependencies. Since there's no partial

dependency, it's already in 2NF. Similarly, it's already in 3NF and BCNF

November


22 | P a g e

2. For the status of aadhar card,

create table status(enrollment_id int, dated Date, Primary

Key(enrollment_id));

Note : Update anomaly : Time implies date.

Delete/ Insert anomaly : Cannot insert time or date unless a new Enrollment

ID is assigned to it.

1NF - yes

2NF - Since time implies date, we break the status into status(time , date)

and status(Enrollment_ID, time)

3NF - For 3NF, we need to check for transitive dependencies(attribute-

attribute dependencies). Here, none exist so we move ahead.

3. Another entity to be represented in the form of a table would be Aadhar Card

DDL Statement :

create table Aadhar_Card(uid int, gender varchar, address varchar,

biometric_data varchar, Primary Key(uid));

NORMALIZED : Update anomaly : Biomertric data implies Address, UID implies

biomertric.

Delete/Insert anomaly : Unless biomertric data is inserted, cannot

get a UID

1NF - yes

2NF - Aadhar_Card(UID int, Gender varchar, Address varchar,

bio-metric_data varchar, Primary Key(UID) TO

Aadhar_card1(uid, Biometric_data)

Aadhar_card2(uid int, gender varchar,address varchar, Primary

Key(UID))

4. For Location,

create table Location(pin_code int, location_name varchar, Primary

Key(pin_code));

Note : Update anomaly : PIN CODE implies NAME.

delete/insert anomaly : Unless PIN CODE is inserted, cannot get the

November


23 | P a g e

location's name.

TABLE DECOMPOSES TO ( AFTER NORMALIZING )

Location1(pin_code, location_name)

We stop at 2NF, further decomposition not possible.

5. For Duration,

create table Duration(begin_date date, end_date date, Primary Key(begin_date));

Note : Update anomaly : begin_date implies end_date. If i update

begin_date, need to update end_date

Insert anomaly : Can't find end_date unless we have begit_date .

Already in 1NF. For 2NF, Duration(begin_date, end_date)

6. For the operator,

create table operator(employee_id int, operator_name varchar)

Note : No anomalies

THE FUNCTIONAL DEPENDENCY DIAGRAM :

November


24 | P a g e

Now, coming over to the relationships the first relationship we encounter is

register_for_aadhar

create table register_for_aadhar(

pin_code int not null,

ID int null,

successful varchar,

Primary Key(pin_code, ID),

foreign key(ID)

references citizen,

foreign key(pin_code)

references location);

Note : There won't be any update anomaly.

Insert anomaly : Unless i insert, location or ID, can't get

successful/unsuccessful

Normalization : 1. Already in 1 NF

2. No partial dependencies so WE STOP at 1 NF. The table is already normalized

November


25 | P a g e

2. enroll

create table enroll(

ID int not null,

Enrollment_ID int not null,

UID int not null,

foreign key(ID)

references citizen,

foreign key(Enrollment_ID)

references status,

foreign key(UID)

references Aadhar_Card);

Note : Update anomaly : Enrollment ID implies UID, UID implies ID

Insert anomaly : We don't have a UID unless we have an enrollment

ID.

Normalization : a) Already in 1 NF

b) For 2NF , since enrollment_id implies UID, we decompose enroll into

enrol1l(enrollment_id, UID) and

enroll2(UID, ID)

Further decomposition not possible.

3. member_of_family

create table member_of_family(

ration_card_id int not null,

UID int not null,

ID int not null,

primary key(ration_card_id, UID, ID),

foreign key(ration_card_id)

references family,

foreign key(UID)

references Aadhar_Card,

foreign key(ID)

references citizen);

Update anomalies : UID implies ID. If a tuple of ID is updated , we

need to update the corresponding data for ration card too .

Insert anomalies : We don't have an ID unless we have a UID

November


26 | P a g e

Normalization : 1) IN 1NF

2) For 2NF, we create

member_of_family(UID, ration_card_ID) and

member_of_family1(UID, ration_card_id)

We stop at 2nf.

4. update

create table update(

ID int not null,

UID int not null,

ration_card_id int not null,

uploaded_ documents varchar,

primary key(ID, UID, ration_card_id),

foreign key(ID)

references citizen,

foreign key(UID)

references Aadhar_Card,

foreign key(ration_card_id)

references family);

INSERT ANOMALIES : UID implies ID. If a tuple of UID is updated, we

need to update the corresponding ID, ration_card_id, uploaded documents too.

UPDATE ANOMALIES : We don't have an ID unless we insert a UID.

For NORMALIZATION, we decompose,

update1(UID, ID) and

update2(UID, ration_card_id,uploaded_documents)

This is the most normalized form so we stop at 2NF

5. works_as

create table works_as(

ID int not null,

employee_ID int not null,

November


27 | P a g e

primary key(ID, employee_ID),

foreign key(ID)

references citizen,

foreign key(employee_ID)

references operator);

Update anomalies : Employee_ID implies ID. If i update a tuple of employee_id,

the corresponding values of ID also need to be updated .

Insert anomalies : We don't have an ID unless we have an Employee_ID

Straight away moving to 2NF for normalization, we create

works_as1(Employee_ID, id)

We stop at 2nf. Further normalization not possible.

6. manage

create table manage(

demographic_details varchar not null,

employee_ID int not null,

UID int not null;

primary key(employee_ID, UID),

foreign key(employee_ID)

references operator,

foreign key(UID)

references Aadhar_Card);

Update anomalies : Employee_ID determines UID. If i update a

value of Employee_ID in a tuple, the corresponding values of demographic_details and UID also

need to be updated.

Insert anomalies : Cannot insert UID without inserting an

Employee_ID and demographic_details.

For 2nf, manage1(employee_id, uid)

manage2(uid, demographic details)

November

4. DDL STATEMENTS QUERIES/SNAPSHOTS

After completing the normalization process till 3NF/BCNF, we moved on

to writing and executing the queries in postgres. We wrote a total of 30

JDBC Connectivity explored for lab case study :

We created a new table named CREDENTIALS. This table had ID,

USERNAME and a PASSWORD as it's attributes. This table was created

specifically for the purpose of creating a GUI which was authentic and

required a login into the aadhar card database.

November


57 | P a g e

WHAT WE DID :

We were guided to create a MAIN Class ( Run class ), a

DBConnection class.

DBConnection.java

November


58 | P a g e

The RUN. java file is shown below :

November


59 | P a g e

After creating these two classes, we executed the queries we

wrote on the console in NETBEANS. Insert : For inserting into the database, this is the format to INSERT.

November


60 | P a g e

GUI DESIGN :

Functionalities included :

1. Authentication : Firstly, the person would login. If the login is authentic,

he/she can go in the database further to UPDATE or DELETE the tuples.

November


61 | P a g e

Here is how it happens..

Step 1 : Login. Say a person named Rooney with a password 189 tries to

login .

November


62 | P a g e

As can be seen, ROONEY has the password 189, So he would successfully

LOG IN to the database. We return the citizen_name and the address of

ROONEY when he logins. Citizen_name is his actual name, provided the

USERNAME is his dummy name or a nick .

ON the net beans CONSOLE : ( after step-1 )

2. Step 2 : Now suppose, the person Rooney(actual name 'bucky') wishes

to update the database say his name and address, then

Before UPDATE :

November


63 | P a g e

DURING UPDATE

Suppose the person bucky enters his new name as Rachit and

some address...

AFTER UPDATE

ON THE CONSOLE

IN THE DATABASE :

Earlier corresponding to 89 id, we had BUCKY, now updated with Rachit and a new address.

November


64 | P a g e

Step 3: For delete (from the table citizen2)

Now if Rachit wants to delete his data,

He presses delete and

Before in database : ID 89 corresponds to Rachit before deleting,

November


65 | P a g e

After deleting :

Thus in this way, we LOGIN, UPDATE and DELETE the data in the UID

database.
