Department of Electrical & Electronics Engineering
• Nowadays many android application are available which provides many smart things to
the users. Google’s operating system in mobile phones are still relatively new, however
android operating system has been progressing rapidly.
• The student information system would be a new way to record and manage the
transaction processing that would achieve efficiency on processing student information.
It would be great help to the administrative personnel, academic personnel, students in
updating and generating student data.
• The developed android application will be used by teachers, students and administrator
who maintains the system. The student will use the application to enter their personal
and academic details. The administrator can verify the details entered by students.

4. OBJECTIVES:

• The main objective of the student information system project is we want to provide
this to our college so that parents or students can check their assessements scores,
attendance details, university events through this app.
• Student information system is a critical tool to manage the student data through out
the entire student life cycle- from new admission right upto alumini information.
• It works by creating a digital database of every single student within a central cloud
location.
• It ensures that student data is centralized at one location, accessable by teachers,
parents and students and is secured by access restrictions.

5. What is Android?

Department of Electrical & Electronics Engineering
• Google’s Android operating system is a mobile-based open-source platform. Nowadays,
most smartphones, tablets, televisions, and other devices like even your Fitbit run on
android. Android is based on top of the Linux kernel(modified version).
• Since Android is open-source, anyone can download the source code, edit it according to
his requirements, and launch his own custom ROM. As a result, Android is available for
almost all devices, irrespective of the manufacturers.
• It provides you with facilities like SDK(also known as the software development kit) to
write your codes, debug them, and make awesome apps for every generation.

6. Why Android?

• Android itself being widely used across the world makes it essential for developers to
choose android. There are other operating systems such as IOS, Ti zen, etc.
• Most Apple smartphones use IOS as their mobile operating system. Most of the
smartphones available in the market use Android as their operating system, making it
available to more users.
• It is not just why android is so essential, but several Android features make android
quite valuable for the current scenario.

7. Features of Android

1. Most of the users in the world use android smartphones:
As discussed before, around 72% of the total users use android. Moreover, this
percentage may even rise in the coming years. Considering this fact, it becomes essential
for any company to develop applications that are supported on android.
2. Interactive User Interface and efficient user experience:
Android provides exciting widgets and tools to make your creativity and imagination turn
into reality. Android developers keep on adding exciting features and widgets to make the
user interface quite interactive and smooth. You can use these tools to make your design
and then publish that design.

3. Larger Community Support:
Google being the holder of Android, regularly updates forums, provides stable releases
and supports all budding developers. One can use their developer guides, tools, and
discussions to resolve their bugs and developmental issues.
As the community is quite extensive and Android is open source, it is easy to develop
such exciting apps without any difficulty.
4. Easy to share your work and earn money:
Google provides flexibility in distributing the apps developed by anyone. After one
develops an app, he or she can quickly go to the Google Play store to publish his/her app
and then earn money. It doesn’t stick to the Google Play store. One can even share his/her
app through other app stores of other manufactures or even directly share through any
network.

5. Regular Updates and Security Fixes:
Google always tries to give its user the best experience and security. To maintain such
standards, google updates android to its latest stable version with the least to often no
bugs and security issues. Therefore, one can assure safety while working on the stable
versions of android.

10. Android Architecture:

11. Android Architecture:
www.cambridge.edu.in
Department of Electrical & Electronics Engineering
Any Operating System has its architecture to carry on various functionalities.
Similarly, android has its architecture. The android architecture gives us an idea about
its design and the build. The architecture can be subdivided into further categories as
below:
1. Linux Kernel
Linux Kernel carries all the drivers for the low-level devices like Audio Driver, Wi-Fi
Driver, Flash Memory Driver, Bluetooth driver, Camera Driver, Keypad Driver, etc. It
is also the abstract layer of android.
2. Libraries
There are several libraries to provide various functionality for purposes like android
development. These libraries are written in C/C++ and are an essential part of
architecture.

12. Android Architecture(contd)

3. Android Runtime
It provides us with an environment for executing and debugging our android
applications.
4. Application Framework
It has many packages in it which are implemented in Java.
5. Applications
At the top level of the architecture, you have the applications. Applications can be of
system or user or even kept by the OEM manufacturers. Phone, Messaging, Camera,
Gallery, etc., are some of the standard applications present in any android device.

13. Student Management System Modules:
www.cambridge.edu.in
Department of Electrical & Electronics Engineering
• Student Information Management: The data that is gathered from the student information
must be secured in this system. These data were composed of the student’s basic
information and academic status.
• Enrollment Management: This is the process where the system takes care of the
requirements provided by the student enrollees. They will require the birth cert of the
enrollees as well as their academic status that will serve as their basis if the student is new
or continuing.
• Grade and Subject Management: This module designates the instructors per subject to
every student or enrollees.
• Grading System: The grading system module will sum up and calculate the given output
by the students and the result would the academic performance of every student. This will
monitor the student’s performance and behavior throughout the period.

14. System Modules(cont):

• Fee and Payment Management: Management of fees and payments is also covered
in the student management system. The fee and payment information is processed
from the enrollment and then the parents or students will be updated about their
accounts to avoid conflicts.

15. DATABASE DESIGN:
