🚨 Google to implement AI for age verification

Google is introducing an AI-powered age verification system across its services, including YouTube, to better enforce age restrictions. This machine learning model will assess whether users are above or below 18 years old to ensure appropriate content filtering.

The initiative comes in response to increasing regulatory demands for enhanced child safety online and is part of Google's wider strategy to embed AI technologies throughout its platforms. The rollout will initially target key markets, with plans for a global expansion in the future.

Advanced SQL Optimization Tips for Data Analysts

1. Use Proper Indexing
Create indexes on frequently queried columns to speed up data retrieval.

2. Avoid `SELECT *`
Specify only the columns you need to reduce the amount of data processed.

3. Use `WHERE` Instead of `HAVING`
Filter your data as early as possible in the query to optimize performance.

4. Limit Joins
Try to keep joins to a minimum to reduce query complexity and processing time.

5. Apply `LIMIT` or `TOP`
Retrieve only the required rows to save on resources.

6. Optimize Joins
Use INNER JOIN instead of OUTER JOIN whenever possible.

7. Use Temporary Tables
Break large, complex queries into smaller parts using temporary tables.

8. Avoid Functions on Indexed Columns
Using functions on indexed columns often prevents the index from being used.

9. Use CTEs for Readability
Common Table Expressions help simplify nested queries and improve clarity.

10. Analyze Execution Plans
Leverage execution plans to identify bottlenecks and make targeted optimizations.

Happy querying!
