Solution Strategy

4. Solution Strategy

A summary and explanation of the fundamental decisions and solution strategies that shape system architecture.

The Dastan solution is broken down in to multiple systems, each with a unique responsibility and grouped functionality. Each system, though different in purpose, is built using similar technologies and patterns.

4.1. Technology Decisions

This section outlines the key technological choices made during the design and development of the Dastan platforms. It covers decisions related to programming languages, frameworks, databases, and other technology-specific aspects that significantly influence the system’s architecture.

Table 4.1 Technology Decisions
Item	Explanation
Monolithic Architecture	The Dastan platforms adopts a monolithic architecture to simplify development and deployment. This design choice is made to optimize development resources and ensure a quick time to market.
Web Framework	The system’s web application is built using React, a JavaScript library for building user interfaces. React is chosen for its component-based architecture, which enables the creation of reusable UI elements.
Database Technology	Microsoft SQL Server is chosen as the primary database technology for its robust features, scalability, and compatibility with the system’s requirements.

4.2. Top Level Decomposition

The Top-Level Decomposition section describes the architectural structure and organization of the Dastan platforms at a high level. It includes decisions related to the overall system design, architectural patterns, and design patterns chosen to create a coherent and effective system architecture.

Table 4.2 Top-Level Decomposition
Item	Explanation
Use of Event-Driven Architecture	The system leverages an event-driven architecture to enable real-time communication between interfaces. This design choice ensures efficient handling of asynchronous processes, fostering responsiveness and flexibility.
Adoption of Hexagonal Architecture	Hexagonal architecture is employed to encapsulate business logic within a core domain, allowing easy adaptation to different interfaces and external systems. This enhances the system’s adaptability and maintainability.

4.3. Key Quality Goal Strategies

In this section, the focus is on strategies adopted to achieve key quality goals for the Dastan platforms. Quality goals may include scalability, security, performance, and other attributes crucial for the success of the system. The section outlines specific decisions and approaches to ensure these quality goals are met.

Item	Explanation
Scalability Strategy	Horizontal scalability is prioritized to accommodate the anticipated growth in users and advertising content.
Security Measures	Security is paramount, with the implementation of industry-standard encryption for data in transit and at rest. Access controls and secure APIs are enforced to protect user data and maintain system integrity.

4.4. Organizational Decisions

The Organizational Decisions section covers decisions related to the project’s organizational aspects. This includes the development process adopted, collaboration strategies, and any delegation of tasks or responsibilities to third parties. Organizational decisions play a crucial role in shaping the workflow and efficiency of the development and maintenance processes.

Table 4.4 Organizational Decisions
Item	Explanation
Agile Development Process	The development process follows Agile principles to ensure flexibility, collaboration, and incremental improvements. Regular sprints and feedback loops facilitate quick adaptation to changing requirements.
Continuous Integration and Deployment	Continuous integration and deployment are adopted to ensure a smooth and efficient development process. This allows for the rapid deployment of new features and bug fixes.
Git Version Control	Git is used for version control to enable efficient collaboration and version management.
GitHub Repository	GitHub is used as the primary repository for the project. GitHub is chosen for its robust features including issue tracking, pull requests, and code review.
Third-Party Collaboration	Certain non-core functionalities, such as analytics and reporting, are delegated to third-party services to leverage specialized expertise and optimize development resources.
