CHAPTER 1 OVERVIEW OF THE RESEARCH TOPIC

General introduction to the topic of the Thesis The context of its emergence, the

practical demand for the product, or scientific research

1.1 Reasons for choosing the thesis/The urgency of the thesis

1.2 Research objectives

1.3 Research subjects, application scope

1.4 Research tasks

1.5 Research methods

1.6 Achievements of the Thesis

1.7 Plan for implementing the thesis

1.1 Reasons for choosing the topic, research field

In our digital age, social media and e-commerce have merged to transform the shopping experience People now look to social media not only for interaction but also for discovering diverse products and seamless online shopping options A social platform that integrates shopping experiences can attract and engage a wide audience, meeting their need for both connectivity and convenience

1.2 Research objectives

Understanding users and their needs: It's crucial to develop a strong grasp of the target user group, including their behaviors, preferences, and expectations when engaging with social platforms This insight informs the design and development process,

ensuring the platform meets user needs and fosters a satisfying, interactive experience

The research goes beyond creating a high-quality social media application, aiming to advance the field of information technology and provide valuable solutions for users and businesses alike

1.3 Research subjects, application scope

The primary research subjects of this project are users—individuals who actively engage with the social media platform for content sharing, networking, and community interaction Researching user behavior, needs, and engagement patterns 1s essential to crafting a social platform that supports meaningful connections and user

retention

In terms of application scope, this project focuses on developimg a social media

platform that enables users to share posts, connect with others, and engage in

community discussions The platform will support content management, user profile

customization, and activity feeds, while mntegrating features like messaging for real-

time interaction and possibly online support for enhanced user assistance

User Demand Analysis: Investigate and analyze the needs of users and social

trends to define essential features for the platform

System Design: Develop the system architecture, database design, and user interface based on the gathered requirements

Feature Development: Program and implement core functions, such as profile management, content sharing, news feeds, and messaging

Testing: Conduct comprehensive testing to ensure all features function smoothly and efficiently

Feedback and Iteration: Gather user feedback to assess the platform's

effectiveness, making continuous improvements based on user experience

1.5 Research methods

The research methods for a thesis on social media technology products often involve a blend of theoretical research, analysis, design, and experimentation For this project, the specific methods include:

Analysis and Design: Conduct in-depth analysis of user needs and behaviors to inform database design and data models, focusing on how users interact on the platform Identify core social media functions, such as profile creation, content sharing, and messaging

Development and Testing: Build and implement the system using technologies like Spring Boot, JavaScript, or Node.js, ensuring smooth operation of all platform features Conduct rigorous testing to verify functionality, usability, and performance

Evaluation: Gather feedback from users to assess the platform's effectiveness, driving

continuous improvement and alignment with user expectations

These methods ensure the final product aligns with user needs and adheres to industry standards, supporting future opportunities to explore and integrate new technologies in

social media development

1.6 Achievements of the thesis

Creating a user-friendly social media platform with an attractive interface that delivers essential social networking functions Develop a comprehensive and efficient database model to support smooth interactions and data management on the platform

CHAPTER 2: BASIC THEORITICAL

2.1 Introduction to Java Spring Boot

2.2 Introduction to Spring Security

2.3 Microservices

2.4 Analyze topics with UML

2.4.1 General USE CASE diagram

2.4.2 Squece Diagram

2.4.3 Details USE CASE diagram

2.1 Introduction to Java Spring Boot

The Java Platform is a software framework developed by Oracle to support building and running Java applications It provides a dedicated environment that allows developers to focus on building applications without being overly concerned about managing memory,

system resources, or execution flow

Java offers a vast library of classes and a robust runtime environment (JVM - Java Virtual Machine), supporting languages like Java, Kotlin, and Scala It includes features like

generics, streams, multithreading support, and lambda expressions, which enhance both application performance and development productivity

2.2 Introduction to Spring Security

Spring Security is a powerful Java framework within the Spring ecosystem, designed

to simplify the creation of secure web applications It provides comprehensive

authentication, authorization, and protection against common vulnerabilities, helping

developers secure applications effectively

Spring Security offers flexibility through configurations for various security needs,

including web-based applications, REST APIs, and OAuth? support for social logins

and single sign-on (SSO) For example, HTTP Basic and Form-Based authentication are standard for simple setups, while OAuth2 enables secure integrations with external identity providers This modularity allows developers to tailor security configurations

to specific project requirements, ensuring a secure and maintainable application

12

2.3 Microservices

In a microservices architecture, applications are decomposed into smaller,

independent services, each responsible for a specific business function Unlike the MVC pattern, which organizes code within a single application structure,

microservices separate functionality into distinct services, allowing each to be

developed, deployed, and scaled independently

Key components in microservices include:

Service Components: Each service focuses on a single business capability and

maintains its own data, encapsulating business logic and data management within that service

APIs: Services communicate with each other through lightweight APIs, often using REST or messaging protocols like gRPC, to enable interaction and data sharing across

the system

Service Discovery and Load Balancing: Mechanisms to locate services dynamically and distribute traffic efficiently ensure resilience and scalability

Centralized Management and Monitoring: Tools for logging, metrics, and health

checks enable tracking, monitoring, and managing service interactions across a

distributed environment

Microservices make it easier to develop, deploy, and scale parts of an application independently, fostering agility and resilience, especially in complex, high-traffic applications
