What does means System Design and Implementation?

System design is the process of defining the architecture, interfaces, and data for a system that satisfies specific requirements. It involves creating a coherent and efficient system that meets the needs of a business or organization. When your organization determines its requirements, system design allows you to build a physical design that addresses customer needs. This encompasses everything from hardware and software to data storage and retrieval1.

System design requires a systematic approach, considering various aspects such as scalability, reliability, and performance. It involves decisions about how components interact, how data flows, and how the system handles failures. Some key concepts in system design include:

Horizontal and Vertical Scaling: Strategies for handling increased load by adding more servers (horizontal scaling) or enhancing existing servers (vertical scaling).

Microservices: Architectural style where applications are broken down into smaller, independent services.

Proxy Servers: Intermediaries that handle requests between clients and servers.

CAP Theorem: Trade-offs between consistency, availability, and partition tolerance in distributed systems.

Storage Types: Block storage, file storage, and object storage.

Message Queues: Systems like Kafka for managing asynchronous communication.

Database Choices: Relational databases (e.g., MySQL, PostgreSQL) and non-relational databases (e.g., MongoDB).

Distributed Systems: Understanding failures, scalability, and design patterns.

Web Applications: Scalability, caching, and load balancing.

Containerization: Using technologies like Docker for deployment.

Cloud Services: Leveraging cloud platforms for scalability and reliability.

On the other hand, system implementation refers to the set of procedures performed to complete the design outlined in the approved systems design document. It involves testing, installing, and beginning to use the new or revised information system2. In essence, implementation brings the design to life, transforming it into a functional system that users can interact with.

In summary, system design focuses on creating a blueprint for a system, while implementation involves turning that blueprint into a working reality.

Md Foysal Ahmed Yes, System design and implementation in the context of your project on creating a deep learning model for Human Activity Recognition involve several key steps:

System Design: This phase involves conceptualizing the architecture and components of your deep learning model. You'll need to consider factors such as the choice of neural network architecture, data preprocessing techniques, feature extraction methods, model training strategies, and evaluation metrics. System design also encompasses designing the overall workflow, including data collection, labeling, model training, validation, and deployment.

Implementation: Once the system design is finalized, you'll move on to the implementation phase, where you'll write the code to build and train your deep learning model. This involves coding the neural network architecture using a deep learning framework such as TensorFlow, PyTorch, or Keras. You'll also implement data preprocessing steps, feature extraction algorithms, training algorithms, and evaluation procedures.
