2 Problem Formulation / Analysis

This chapter provides an analysis of the theoretical background relevant to my internship

work in Java development at Shiash Info Solutions. The internship primarily focused on
backend development, emphasizing Java’s role in creating scalable, secure, and efficient
applications. Understanding key theories in software development, Java programming, and
database management was essential to contribute effectively to the projects assigned.

1. Java Programming Fundamentals

 Java is a widely-used, object-oriented programming language known for its

portability, security, and performance. Core concepts in Java, such as object-oriented
programming (OOP) principles, encapsulation, inheritance, polymorphism, and
abstraction, formed the basis of my development tasks. By applying OOP principles, I
was able to structure the code into reusable, modular components, which are essential
for creating scalable applications.
 Additionally, understanding exception handling and multi-threading in Java was
crucial. Exception handling ensured the program ran smoothly, even when unexpected
errors occurred, while multi-threading allowed efficient management of concurrent
tasks, improving the overall responsiveness of applications. These concepts are
fundamental in creating robust applications in Java.

2. Software Development Lifecycle (SDLC)

 Shiash Info Solutions follows the Agile development methodology, which is an

iterative approach to project management and software development. Agile is
characterized by regular feedback, incremental progress, and a focus on delivering
small, functional components of the application. This methodology allowed me to
understand how requirements evolve over time and how adaptability is crucial for
meeting client needs effectively.
 Familiarity with the Software Development Lifecycle (SDLC) stages—planning,
designing, coding, testing, deployment, and maintenance—was essential for
understanding how my contributions fit into the broader project timeline. Each phase
of SDLC emphasizes a specific aspect of development, ensuring the final product is
well-structured and meets quality standards.

3. Database Management with MySQL

 Database management is critical for backend developers, and MySQL is a popular

relational database management system (RDBMS) that is widely used for handling
data in web applications. I gained experience with SQL (Structured Query
Language) for querying and manipulating data in the MySQL database, learning to
perform operations such as data retrieval, insertion, updating, and deletion.
 Additionally, understanding concepts like data normalization and indexing was
essential for optimizing database performance. Normalization helps minimize data
redundancy, making the database more efficient, while indexing speeds up data
retrieval, enhancing application responsiveness. These database management skills

18
 allowed me to create a solid backend that supports data-driven functionalities
efficiently.

4. Version Control Systems and Collaborative Development

 Version control systems (VCS), especially Git, are critical in collaborative

development environments like Shiash Info Solutions. Git allows multiple developers
to work on the same codebase without conflicts, tracking changes, and providing a
reliable mechanism for rolling back to previous versions if necessary. During the
internship, I learned to use Git for managing code changes, creating branches for
feature development, and collaborating with team members through pull requests.
 By integrating version control into the development process, I was able to work on
individual components independently, merge code seamlessly, and maintain code
integrity across multiple versions of the project. This collaborative approach
improved productivity and made teamwork more efficient.

5. Software Security Principles

 Ensuring application security is a top priority in professional development. I learned

about fundamental security principles, such as data encryption, secure
authentication, and authorization practices, to protect user data and application
resources. Understanding security helped me design code that adheres to best
practices, reducing potential vulnerabilities.
 Additionally, implementing input validation and data sanitization was crucial in
preventing security risks such as SQL injection and cross-site scripting (XSS). These
practices contribute to building secure, reliable applications that can be trusted by
users and clients.

6. Deployment and Server Management

 In a real-world setting, code doesn’t just need to work—it needs to be deployed on

servers for users to access. I gained experience with Apache Tomcat, a Java
application server, which is commonly used for deploying Java-based applications in
professional environments. This experience included configuring server settings,
managing application deployment, and troubleshooting server-related issues.
 Understanding deployment was essential for translating development efforts into a
user-accessible format, bridging the gap between local development and production
environments. This exposure provided insight into the importance of testing and
validation in both pre-deployment and post-deployment stages, ensuring applications
function as expected.

5 Merits of the Project

The proposed system uses cloud-of-clouds replication of encrypted and encoded data
to avoid having any cloud service provider as a single point of failure, operating correctly
even if a fraction of the providers unavailable. This system uses cloud of clouds which
means, the metadata of the data will be stored and maintained on the separate cloud storage
for efficient sharing. It provides a data centric design where it does not depend on a single
cloud provider, data centric design. For that purpose, it uses leasing protocol to avoid the
write conflicts between the data. It is a distributed file system that provides an interface to
access an ecosystem of multiple cloud services and allows data transfer between clients.

Advantage of Proposed System:

 Due to the Cloud of clouds architecture the metadata is maintained to manage the
cloud stored data.
 Handles the big data in a secure and reliable way.
 Efficient Encryption scheme on every file chunk ensures the enhanced security
level.
 Sharing the specific encrypted data among the dataset without disturbing to the
other sets is maintained.
