Yоu аre аnаlyzing a serverless web applicatiоn hоsted entirely in the AWS Cloud. The app allows users to upload short text messages and associated image files, which are then processed and stored for later retrieval. The application architecture includes the following components: User Web Browser: The client interface where users write messages and upload images. Amazon API Gateway: The front-end entry point exposes RESTful APIs to the browser. AWS Lambda Functions: One Lambda function validates user inputs (e.g., message content and file type). Another Lambda function processes the uploaded image (e.g., resizing, metadata extraction). Amazon S3: Stores the uploaded and processed image files. Amazon DynamoDB: Stores text messages and metadata associated with each uploaded image (e.g., upload time, user ID, image reference). Amazon Cognito: Manages user authentication (sign-up, login, token generation). The system is designed with scalability, security, and efficiency in mind. Based on the above scenario: Identify and define the principles of Data Flow Diagram (DFD) components: External Entities (Who/what interacts with the system?) Processes (System activities that transform data) Data Stores (Where the data is stored) Data Flows (How data moves between components) For each component you identify, briefly explain your reasoning (i.e., why it fits that DFD category in this context). Directions for answering the question: Organize your answer clearly by DFD component type (External Entities, Processes, Data Stores, Data Flows). Your reasoning should directly reference the cloud services and roles described in the scenario. Be concise but complete — imagine you are preparing a first draft of the system's Level 1 DFD. Use only the information provided and the concepts learning in the classroom. You do not create and submit a DFD; create a table similar to the following one with the information that is part of your DFD. Component (flow, data store, external entity, process, boundary) Boundary (defines each boundary, which contains the component) Description Rubric Criterion Excellent (Full Points) Partial (Some Points) Poor (Few/No Points) Points 1. Correct Identification of External Entities (4 points) Accurately identifies both external entities (User Web Browser and Amazon Cognito) with correct classification. (4 pts) Identifies only one external entity correctly or makes minor classification errors. (2-3 pts) Fails to correctly identify external entities or misclassifies internal components as external. (0-1 pts) ____ / 4 2. Correct Identification of Processes (4 points) Correctly identifies the processes (API Gateway, Lambda Validation, Lambda Image Processing) and classifies them as activities that transform data. (4 pts) Identifies some but misses or misclassifies a process (e.g., calling storage a process). (2-3 pts) Misclassifies components or does not describe processes properly. (0-1 pts) ____ / 4 3. Correct Identification of Data Stores (4 points) Correctly identifies Amazon S3 and DynamoDB as data stores and explains their roles. (4 pts) Identifies only one data store correctly, or explanation lacks depth. (2-3 pts) Fails to identify correct data stores or incorrectly classifies processes as stores. (0-1 pts) ____ / 4 4. Correct Identification of Major Data Flows (4 points) Clearly identifies major data flows between components (e.g., User → API Gateway → Lambda → S3/DynamoDB) and explains directionality. (4 pts) Mentions data flows but omits key ones or describes flows unclearly. (2-3 pts) Major misunderstandings about how data moves, or very incomplete/missing flows. (0-1 pts) ____ / 4 5. Clarity and Quality of Reasoning (4 points) Each DFD component is accompanied by a clear, logical, and concise explanation showing good understanding of roles and boundaries. (4 pts) Provides reasoning, but some explanations are shallow, vague, or slightly inaccurate. (2-3 pts) Reasoning is missing, incorrect, or shows little understanding of the system roles. (0-1 pts) ____ / 4
The аbоve figure shоws the structure оf а ______________________, аnd the red line indicates the backpropagation flow. This model has an input, hidden, and output layer. The hidden layer contains a memory cell with three gates: input gate, forget gate, and output gate. By adding gate structures in a memory cell, this model can consider long-term dependencies from long-sequence data. Overall, this model is a relatively suitable model for time series data compared to other neural network models.
