Architecture Design Summary: You need to submit two assignments here: 1) The Non-Functional Requirements excel sheet. 2) A summary of Architectural Design document - what Architecture are you using and why: Thin Client-Server, or Thick Client-Server and why? 2-Tiered, 3-Tiered, or N-tiered and why?

Hardware/Software Specification Summary: Submit Hardware/Software Specification. You can submit any type of document, but it must cover your client (if any) and your servers (if any). For example, if you list a 3-Tiered client-server Architecture than what Hardware and Software will your client need, and what Hardware and Software will your two Servers need? Like the text, you must cover the Hardware, Software, OS, and Network requirements.

Paper For Above Instructions

In the field of software architecture, the selection of an appropriate architecture is crucial for meeting both functional and non-functional requirements. This paper discusses the chosen architectural design, outlines the rationale for the selection of client-server models, and provides an overview of the necessary hardware and software specifications.

Architectural Design Summary

The architectural design chosen for this project is the 3-Tiered Client-Server architecture. This architecture comprises three distinct layers: the Presentation Layer, Business Logic Layer, and Data Access Layer. The choice of the 3-Tiered architecture is based on several factors such as scalability, manageability, and the ease of maintenance.

The Presentation Layer handles the user interface and user interactions, ensuring that the system is easy to use. The Business Logic Layer processes the core functionality and logic of the application, while the Data Access Layer interacts with the database and manages data storage and retrieval. This separation of concerns allows for a more organized application design and provides flexibility for updates and modifications without affecting other layers.

The reasons for selecting a 3-Tiered architecture over options such as Thin Client or Thick Client architectures are as follows:

• Scalability: A 3-Tiered architecture can support a growing number of clients by allowing each layer to be scaled independently, thus enhancing the overall system capacity (Roberts, 2020).
• Maintainability: Changes in one layer do not necessitate changes in another, making it easier to maintain and update the system (Sharma, 2019).
• Security: By separating data storage, business logic, and presentation, the system can enforce security measures at each layer (Smith, 2021).

Non-Functional Requirements

The Non-Functional Requirements (NFRs) are essential to ensure that the system functions effectively under various conditions. Some key NFRs for this architecture include:

• Performance: The system should respond to user inputs within 2 seconds.
• Security: User data must be encrypted during transmission and storage.
• Reliability: The system should have an uptime of 99.9%.

To document these requirements, a detailed excel sheet will be prepared, correlating to each tier of the architecture and defining performance metrics for each.

Hardware and Software Specification Summary

This section outlines the hardware and software requirements for both the client and server components of the 3-Tiered architecture. The requirements will vary depending on the specific functionalities of the application, but a general overview is provided below.

Client Hardware and Software Requirements

• Hardware:
  • Processor: Dual-core 2.5 GHz or better
  • RAM: 8 GB minimum
  • Storage: 250 GB SSD or higher
  • Network: Gigabit Ethernet or Wi-Fi 5/6
• Software:
  • Operating System: Windows 10 or newer, or macOS Mojave or newer
  • Web Browser: Chrome, Firefox, or Edge (latest versions)
  • Any necessary client applications as per the project requirements

Server Hardware and Software Requirements

• Hardware:
  • Processor: Quad-core 3.0 GHz or better
  • RAM: 16 GB minimum
  • Storage: 1 TB HDD or 512 GB SSD (for faster access)
  • Network: Dedicated server with at least 1 Gbps bandwidth
• Software:
  • Operating System: Windows Server 2019 or Linux (Ubuntu Server)
  • Database Software: MySQL, PostgreSQL, or Oracle Database
  • Web Server Software: Apache or Nginx

To summarize, hardware and software specifications must meet the operational needs of the 3-Tiered architecture, ensuring that both client and server components can effectively communicate, process data, and present results to users efficiently.

Conclusion

The selection of the 3-Tiered Client-Server architecture is a strategic choice aimed at fostering scalability, maintainability, and security. By clearly defining the non-functional requirements and outlining the hardware and software specifications, we pave the way for successful implementation and operation of the software application.
