Data Integration:-Combine data from 10 different tables into a single, unified master table.-Ensure data consistency and accuracy during the integration process.SQL Query Optimization:-Utilize views and common table expressions (CTEs) to simplify complex SQL queries and improve performance.-Break down complex queries into smaller, more manageable parts for better readability and maintainability.Colab Script Development:-Create a Python script in Google Colaboratory to automate the process of reading data from multiple spreadsheets.-Implement efficient data extraction and transformation techniques to prepare the data for integration.Data Consolidation:-Merge the data from multiple spreadsheets into a single, unified spreadsheet.-Ensure data consistency and alignment between different sources.Data Validation and Cleaning:-Implement data validation checks to identify and correct errors or inconsistencies in the data.-Clean and preprocess the data to improve its quality and suitability for analysis.

Develop Python Script:-Create a Python script to handle data ingestion tasks, including:-Data extraction from various sources (e.g., csv files)Data transformation and cleaning:-Data loading into a target system like big queryCloud Function Deployment:-Deploy the Python script as a cloud function on a suitable platform (e.g., AWS Lambda, Google Cloud Functions, Azure Functions).-Configure the cloud function's triggers (e.g., time-based, event-driven) to automate the ingestion process.Data Ingestion Automation:-Automate the data ingestion pipeline by scheduling the cloud function to execute at regular intervals or in response to specific events.-Implement error handling and logging mechanisms to monitor the pipeline's health and troubleshoot issues.Version Control with Git:-Initialize a Git repository to track changes to the Python script and configuration files.-Commit code changes regularly with descriptive commit messages.-Use Git branches for feature development and bug fixes to maintain a clean and organized codebase.Configuration Management:-Store configuration settings (e.g., data source credentials, target system details) in external configuration files or environment variables.-Use Git to manage configuration files and track changes.Testing and Debugging:-Implement logging statements to track the execution flow and identify potential issues.-Use debugging tools to step through the code and inspect variables.Deployment and Monitoring:-Deploy the cloud function to the target environment and configure it to run automatically.-Monitor the cloud function's performance, logs, and error rates to ensure optimal operation.-Implement alerts and notifications for critical issues or failures.
