The "Data Normalization Service" challenge focuses on developing an API service that standardizes and cleanses data to ensure consistency and efficiency in data processing.
- Understand the importance of data normalization in database management.
- Implement algorithms and techniques for data standardization.
- Ensure data integrity and accuracy through normalization processes.
-
Objective: Develop a service that normalizes incoming data to a predefined structure or format.
-
Environment Setup: Choose your preferred programming language (e.g., JavaScript, Python, Java, C#) and set up the necessary environment.
-
Implementation Details:
- Endpoints:
- Define an endpoint (
/normalize
) that accepts data via HTTP POST requests and returns the normalized data.
- Define an endpoint (
- Data Normalization:
- Implement algorithms to cleanse and standardize data (e.g., removing duplicates, converting data types, enforcing constraints).
- Ensure that the normalized data adheres to a specified schema or format.
- Validation:
- Validate incoming data to ensure it meets required criteria before normalization.
- Handle edge cases and exceptions gracefully.
- Endpoints:
-
Testing: Test your service using a HTTP client (e.g., Postman, curl).
- Send POST requests to the
/normalize
endpoint with different data inputs and verify that the response contains the normalized data.
- Send POST requests to the
- Integration with Databases: Extend the service to integrate with databases for storing and retrieving normalized data.
- Performance Optimization: Optimize algorithms and data processing techniques for better performance.
- Error Handling: Implement robust error handling for invalid data inputs or normalization failures.
- Versioning: Consider versioning the API to manage changes in data normalization logic over time.
- Scalability: Design the service architecture to handle large volumes of data and scale as needed.
By completing this challenge, you will gain practical experience in developing a data normalization service and learn essential practices for maintaining data quality and consistency in backend systems. Explore additional improvements and challenges to further enhance your skills.
Happy coding!
