COVID-19: ETL Pipeline and Visualization

The primary objective is to utilize Amazon Web Services (AWS) to optimize and automate the COVID-19 data analysis process. By analyzing key parameters like confirmed cases, deaths, vaccinations, and more, across different countries, we aim to gain valuable insights and take necessary actions to combat the virus’s spread effectively.
Raw COVID-19 data is extracted from the trusted source of Our World in Data (OWID) which actively provides COVID-19 information on a daily basis. The process is automated and stored in a designated location for further analysis.
The extracted data is sent for transformation into a format that can be used for analysis and visualization. This may involve cleaning the data, removing duplicate records, and correcting any errors. It may also involve transforming the data into a different data format, such as a star schema or a snowflake schema.
The transformed data is loaded into a data catalog or database for better organization and management. Metadata tables are created to provide a comprehensive view of the data’s structure and characteristics. The data is loaded into a high-performance database cluster for efficient querying and analysis.
The loaded data is connected to a visualization or a BI tool where data is visualized in an interactive and meaningful manner to the user.
This task provides an efficient solution for extracting and analyzing the COVID-19 dataset, leading to valuable insights. By automating data extraction, transforming it into structured tables, and loading it into a centralized database, we enable comprehensive analysis of key parameters.
The visualization component facilitates the generation of informative reports. This project helps individuals by providing timely and accurate information on COVID-19 trends, enabling informed decision-making, and supporting proactive measures to protect their health and well-being.
It empowers individuals with a deeper understanding of the pandemic’s impact, facilitating personal risk assessment and the adoption of appropriate preventive measures.
