2. PROJECT DETAILS:
2.1 ABOUT PROJECT:
The key focus of creating this application is to make a platform which is easily accessible to
public users and helps in managing the interns of this organization.
The purpose is to make a user friendly application which aims to manage the trainees for the
reputed organization Collins Aerospace. The name of the project is “Inter Management”. It
manages separate portals dividing the application into 3 broad categories namely:
1. Administrator
2. Student
3. Mentor
2.2 PROJECT FUNCTIONALITY:
The application offers the following functionality:
1. Firstly the students sign up and get themselves registered by entering all the necessary
details.
2. Student can submit the weekly progress report to the mentor directly from the
application and also submit a leave application to the mentor. Also, the student can
get his certificate after the completion of his training period.
3. Admin can login by entering the username and password. Admin assigns the mentor
to the student and can also add a new mentor to his team. Admin can also remove a
student from the internship. Also, there is a search bar through which the
administrator can search the student with required specifications i.e. search by
institute or search by name.
4. The last section is the Mentor where the mentor can log in and manage its assigned
students for training. Mentor can assign projects to the students individually or in a
group. Mentor receives the WPRs(Weekly Progress Reports) and can approve leave
application submitted by the student.

2.3 EXISTING SYSTEM
The company managed its interns manually by preparing list of students on a very basic
software like Excel. This turned out to be very tedious and bulky task. It was difficult to
manually enter and manage details of all its interns.
The company required a simple, efficient and easy to use application that could provide a
functionality to manage its interns in such a way that allows user to handle the application
without having much knowledge about the application.
Thus to overcome this difficulty, this application was developed so as to eliminate the need
of manually entering all entries. Here it offers a reliable way to manage the sections like
Administrator, Student and Mentor.
2.4 PROPOSED SYSTEM
To overcome the difficulties mentioned under the existing system, proposed system is
established to manage the trainees without having to enter details manually which increased
human effort and was time consuming.
It is easy to operate the proposed system. Also, in the proposed system accuracy level is more
and is user friendly in comparison to the earlier system. This system also helps in eliminating
the shortcomings of the current system to a very large extent.
Aim of new proposed system:
1. Structural approach - The work is done in planned and organized manner.
2. Accuracy- To achieve a high level of accuracy. All operations would be done
systematically and the data or information will be accurate.
3. Reliability- Secure way to store data.
4. Instant access to information – The main focus of this new proposed system is to have
a fast, responsive and reliable access to the data.

3.3 OVERVIEW OF ANDROID
3.3.1 INTRODUCTION
Android is an operating system launched in 2008 by Open Handset alliance (OHA). It is built
specifically for mobile devices including smartphones, tablets, watches, TVs, vehicle
entertainment systems and computers. Android provides a very flexible and consolidated
approach to develop applications which can be used among variety of different devices with
different versions of android operating system. This allows developers to freely develop
applications without thinking about support to various devices and versions.
Open Handset Alliance is supported by Google and few other organisations. Android is based
on touch based inputs and devices can be operated without need of any physical buttons. This
is done to imitate real world actions which allows the OS to be very user friendly. A virtual
keyboard is also provided to take user inputs.

14. Android 8.0” (Oreo)
15. Android 9.0 (Pie)
Android applications are created using languages like Java, Kotlin, C++. The code with all
the resource files is compiled by the Android SDK into an APK(Application Package with
.apk extension). All the contents reside in one APK file of the application and this file is
used by all the Android devices to install the application. There are some security features
for each android application:
1. Android is a multiple -user Linux based operating system which treats every installation
of application as an unique user.
2. As a default opearion, a unique Linux user-id is assigned to each app by the system.
System uses this id for different operations but the id is not known by the app.
Figure 1: Android Version Timeline

7
3. Each application run in isolation with others as each process is assigned with their own
Virtual Machine(VM).
4. Each application run in their “own Linux process. The process begins when any unit of
the application has to be executed and the system ends the process after executing the
task and then retrieves the memory for other processes.
Every application has the ability to access the unit which are required to perform some task.
So the application is restricted to access any other information in the system for which
permission is not granted. There are various methods through which an application can share
data among other apps and can also access to different services of the system:
1. It's conceivable to organize two applications to have a similar Linux client ID, in
which case they can get to one another's records. To monitor framework assets,
applications with a similar client ID can likewise organize to keep running in a same
Linux process and offer the equivalent VM. The applications should likewise be
marked with a similar authentication.
2. An application can demand authorization to get to device information, for example,
the client's contacts, SMS messages, bluetooth, camera, and the mountable storage.
The client needs to unequivocally allow these consents.”
3.3.2 JAVA IN ANDROID APP DEVELOPMENT
Java is an open source programming language made with a simple goal in mind, being able to
run on machines with a variety of different hardware and Operating Systems. Java program
execution process is executed by Java Virtual Machine (JVM). Java code does not directly
compile to machine code but Java compiler converts .java program file to .class file which
contains the byte-code. Now this byte code can be run on any machine with a JVM i.e. Java
Virtual Machine installed in it.
Android uses this property of java to achieve its goal of being a universal operating system
for all kinds of devices.
Java API is provided by Google to get started into android development. Your files can be
compiled into classes using this API. Java is preferred by Android for its development
platform due to various reasons:
1. Java is widely known and used language provided with a huge set of packages and is
supported by open source community.
2. Java provides better security.

8
3. Java is a well-known industry language with most devices compatible with it.
Though the Java API is provided by Google, JVM is not used by Android to execute the class
files. Rather, DVM (Delvik Virtual Machine) is used by Android for the execution process.
The files are then compiled into the DEX(Delvik Executable) format and then bundled
together as APK(Android Package).
The use of DVM makes Android very optimized and power efficient for a large number of
devices and also provides an easy to build platform for programmers.
3.3.3 XML IN ANDROID APPLICATION
Extensible Mark-up Language is a mark-up language like HTML (Hyper Text Mark-up
Language) used to portray information. “XML tags are not predefined in XML. We should
characterize our very own Tags. Xml as itself is well comprehensible both by human and
machine. Additionally, it is versatile and easy to create. In Android” we use xml for
structuring our designs in light of the fact that xml is lightweight language so its usage does
not make out app slower.
3.3.4 USER INTERFACE
The entire idea of creating an User Interface distinguish and use the View Groups and their
objects. Child views are arranged inside a box or container known as View Groups. These
views are treated as different widgets to create a portion of UI. A view group can also be
the child of another view group component as displayed in the diagram given underneath:

9
Figure 2 User Interface components
3.3.5 VARIOUS XML FILES USED:
In android, different XML files are used for different purposes. Some of them are:
1. LAYOUT XML FILE: Layout XML Files are utilized to characterize the actual User
interface (UI) of our application. This file holds each and every element and the tools
that are required for our application.These include the TextViews, Buttons and other
User interface components.
This file is held inside of the res folder and inside it another folder "layout" is present
where we can find each and every format document for their particular exercises or
fragments.
Figure 3 Layout XML File

10
2. MANIFEST XML FILE: This xml file is utilized to characterize every one of the
segments (or components) of the application. This file includes all the names of our
application packages, services, receivers, our Activities and all the required permissions
(consents). Like, suppose we have to utilize internet in our application then we have to
characterize Internet permission in this document.
This file is located in app  manifests folder
Figure 4 Manifest XML File
3. VALUES FILE:
a. Strings File (strings.xml) : This file is used to store various strings which are hard-coded
throughout the app into a single string. All the strings of this file can be used in out layout
file. This promotes reusability of code and helps in make our app easily translatable.
b. Styles File (styles.xml): This file is used to create different themes and styles for the
application’s user interface. We create and store different custom themes inside this file.
c. Drawable xml Files: These files are used to store images, icons, logos and other drawable
items which are to be used inside our application. We can also create custom icons which
can be used by different activities or different xml files.
d. Color File (colors.xml): This file is used to define colour RGB codes. These colors can be
used throughout the app and make sure that our application has a consistent theme.

11
3.4 AMAZON WEB SERVICES (AWS):
AWS is a remote computing service. It provide cheap pay-as-you-go based cloud
computing platform with cloud storage service, bandwidth and support for Application
Programming Interfaces (APIs).
AWS was launched in 2006 by Amazon Incorporation. It was build by IT resource
management team of Amazon but later grew into a very innovative and cost efficient
solution for general public as well as other companies.
AWS was launched during very early phase of cloud computing. Prior to the launch
Amazon was using its host servers below 50% of their capacity so Amazon rebuild its
infrastructure to integrate server and storage. AWS uses same infra as other web services of
Amazon.
AWS is built with scalable and virtually unlimited storage capacity, computing power and
bandwidth.
Its services include.
Amazon” Simple Storage Service (Amazon S3)
Amazon CloudFront
Amazon Relational Database Service (Amazon RDS)
Amazon SimpleDB
Amazon Lambda
Amazon RDS : Amazon Relational Database Service is a web based relational database
service in the cloud that is easier to set-up, operate and is scalable. It provides an easily
resizable and cost-effective solution for industry-standard database and manages common
administrator” tasks.
Amazon RDS helps in managing difficult and tedious management tasks of a relational
database:
Figure 5 String File (strings.xml)

12
 When you purchase a server, you will get CPU, memory, storage, and IOPS, all
together in a bundle. But in Amazon RDS so as to scale them independently, these
are split apart. If we require less IOPS or more CPU or to increase storage, we can
easily allocate them.
 Software patching, managing all backups, recovery and also automatic failure
detection is managed by Amazon Relational Database.
 In order to provide a well-managed service experience, Shell access to database
instances are not provided by Amazon RDS, and also the access to certain system
procedures and tables that need advanced privileges is restricted. Also the advanced
privileges are not given to certain restricted procedures and information
 We can also have automated backups performed whenever we feel the need to do it,
or we can also have our backup snapshots created manually. These backups can be
used anytime to restore any data back in the DB. The process of restoring data is
reliable and efficient.
 We can have high accessibility with an primary instance and a secondary instance
that you can bomb over to when issues happen. MySQL, MariaDB, or PostgreSQL
Read Replicas can also be used to build read scaling.
 Any of the database product like MySQL, Oracle, PostresSQL etc. can be used.
 With the security features in our database packages, access to the RDS database can
also be controlled by us. We can make it secure by controlling who all are allowed
to access the database with the help of Amazon Web Services IAM(Identity and
Access Management). We can likewise increase the protection of our database by
placing it in a virtual private cloud.
3.5 DATABASE:
Database helps us to store a number of information in the form of tables. Without databases
the storage of data is not possible and modern day application will not work as expected.
Databases generally consist of a one or more number of tables which may or may not be linked
together. We can use SQL commands to access, update, insert and carry out operation on the
tables.

13
MySQL Workbench
MySQL server workbench is used to access, manage, administer, and develop all components
of SQL tables and run queries on them, It integrates a large group of graphical tools having a
large number of rich script editors and they allow access of the Server to developers and
administrators of all skill levels.
Figure 6 MySQL Workbench Home page
In our project we have used namely four tables :
1. StudentDetails
2. MentorDetails
3. AdminDetails
4. ActivityTable
The description of the following tables:
1. StudentDetails: It has 10 columns namely studentId, studentName, dob, mobile,
gender, college, branch, currentsem, batch, mentorId and password. This table
is used to keep student records as registered with the organisation as well as
their assigned mentor name.
Figure 7 Student Details

14
2. MentorDetails: It has 3 columns, mentorName, mentorId, mentorPassword.
This table is to be filled by admin to maintain the details of the mentors.
Figure 8 Mentor Details
3. AdminDetails: This table has 3 attributes namely adminId, adminName,
adminPassword.
Figure 9 Admin Details
4. ActivityTable:

6. RESULTS AND DISCUSSION
The android application on INTERN MANAGEMENT application is a better idea over the
manual system i.e. existing system. This android application contains the three different
modules i.e. the admin, the student and the mentor. Each user has to first login before the user
can see the other functionality. Every part has different functionality according to the
requirement of each module. MySQL Workbench is the tool by which the admin maintains the
information required and supervises the activities that have been allotted to the trainees. The
admin can also add new Mentors and assign them to students.
