Non-functional requirements
In developing a student assignment management website, non-functional requirements play a crucial role in ensuring the system operates smoothly, securely, and can be easily expanded Here are some essential non-functional requirements to consider:
1 EF Core Usage to Prevent SQL Injection:
○ Entity Framework Core (EF Core) is a powerful ORM (Object-Relational Mapper) that facilitates data access and manipulation
30 without writing raw SQL queries To ensure protection against SQL injection attacks, EF Core should be used correctly Specifically, queries should utilize LINQ or parameterized queries to avoid directly incorporating user inputs into SQL statements Using methods like FromSqlRaw with parameters or AddParameter helps ensure input values are validated and secured
○ The system should be designed with a modular architecture, allowing easy addition or modification of components without affecting the entire system Implementing design patterns such as MVC (Model- View-Controller) or MVVM (Model-View-ViewModel) helps separate logic, interface, and data components, making maintenance and expansion more manageable Adhering to SOLID principles in coding increases flexibility and ease of maintenance

Clean architecture
Clean Architecture is a software design philosophy that aims to create systems that are easy to maintain, test, and evolve over time In the context of NET Core, Clean Architecture provides a structured approach to organizing code by separating concerns into distinct layers, each with specific responsibilities This separation enhances the overall manageability and scalability of the application.[6]
5.2.1 Core Principles of Clean Architecture
1 Independence: Each layer in Clean Architecture operates independently from others This means that business rules and logic are isolated from technical details like database operations, making the system more adaptable to changes in technology or business requirements
2 Separation of Concerns: Clean Architecture enforces clear boundaries between different parts of the application For instance, business logic is kept separate from user interface logic, which in turn is separated from data access logic This separation ensures that changes in one part of the system do not cascade and affect other parts unnecessarily
3 Testability: By isolating business rules and logic from external dependencies, Clean Architecture makes it easier to write unit tests for core functionalities This leads to a more reliable and maintainable codebase
1 Entities: These are the core business objects that are independent of any external systems Entities encapsulate the most general and high-level rules of the application
2 Use Cases (or Interactors): This layer contains the application-specific business rules and orchestrates the flow of data to and from the Entities Use Cases define the operations that can be performed within the system
3 Interface Adapters: This layer acts as a bridge between the outer layers
(UI, database, external systems) and the inner layers (Use Cases, Entities) It contains controllers, presenters, and gateways to translate data into a form that the inner layers can use without knowing the specifics of the outer layers
4 Frameworks and Drivers: The outermost layer contains all the implementation details This includes the database, user interface, web framework, and any other external services This layer depends on the inner layers but is not dependent upon by them
5.2.3 Implementing Clean Architecture in NET Core
In a NET Core application, Clean Architecture can be implemented by organizing the solution into multiple projects:
1 Core Project: This contains the Entities, Use Cases, and Interfaces It should have no dependencies on any other projects This project represents the domain layer and holds the core business logic and rules
2 Application Project: This layer contains the implementation of the Use Cases It coordinates the flow of data between the core business logic and the external layers
3 Infrastructure Project: This project contains the implementation details related to data access, external services, and frameworks It implements the interfaces defined in the Core project
4 Presentation Project: This project contains the user interface logic, such as controllers, views, and APIs It communicates with the Application layer to process user inputs and present data
1 Flexibility: Clean Architecture allows the system to evolve by making it easier to replace or upgrade individual components without affecting the entire system
2 Maintainability: By enforcing a separation of concerns, Clean
Architecture makes the codebase easier to understand and maintain
3 Testability: With business logic isolated from external dependencies, writing unit tests becomes straightforward, ensuring higher code quality
In summary, Clean Architecture in NET Core promotes a robust, flexible, and maintainable software structure by clearly defining responsibilities and boundaries within the application This approach not only enhances the scalability and adaptability of the system but also ensures long-term maintainability and ease of testing
Design overview
In NET Core, the three packages Api, Core, and Infrastructure represent distinct projects, each encompassing their own dependencies, settings, and library packages The Api project includes the Controllers package, which contains controllers designed to receive client requests, and the Authentication package, which manages authentication issues
The Core project stands as the foundational project, independent of other projects It houses several key packages:
● Entities: Contains Models and DTOs
● Shared: Includes Enums, Utils, Resources, and other shared components
● Interface: Comprises interfaces and abstracts
● Services: Encompasses classes responsible for business logic processing
The Infrastructure project is tasked with handling interactions with third-party systems such as databases, mail servers, message brokers, caches, and more It is crucial for the infrastructure processing layers and business logic to implement the interfaces defined at the core level This setup exemplifies the Dependency Inversion Principle, wherein the business logic typically calls the repository Normally, placing the repository interface at the base of the core would violate the DIP principle Given that repository or infrastructure operations generally involve communication with other systems, which are prone to frequent changes during development, this architecture positions Core as the foundational layer Consequently, infrastructure operations must depend on Core, ensuring that core business services do not directly call the infrastructure but rather interact through interfaces defined within the core This architectural design, combined with implementing Dependency Injection in .NET Core, enhances the system's robustness, making it more adaptable for upgrades and modifications
