Can I use this for performance tuning?

Absolutely. It includes techniques for benchmarking query duration and using EXPLAIN to verify that queries are utilizing indexes rather than performing sequential scans.

How does it handle transaction testing?

The skill includes patterns for testing ACID properties, specifically ensuring that transactions roll back correctly on errors and that concurrent operations are isolated to prevent race conditions.

Is it applicable to NoSQL databases?

While the primary examples focus on SQL-based relational databases, the core principles of data integrity, performance testing, and migration validation can be adapted for NoSQL environments.

Does this skill help with database migrations?

Yes, it provides specific patterns for testing that migrations are reversible, preserve existing data, and correctly update the schema structure.

Database Management

Ensures data persistence reliability through schema validation, migration testing, and transaction isolation verification.

About

This skill provides comprehensive guidance for testing database systems, focusing on maintaining data integrity and performance. It enables Claude to assist developers in validating database schemas, testing the reversibility of migrations, ensuring transaction safety (ACID properties), and optimizing query performance using execution plans. It is essential for teams looking to prevent catastrophic data loss, silent corruption, and performance bottlenecks in production environments.
