MySQL Workbench provides a graphical interface for monitoring database performance. It includes tools for visualizing server status and performance metrics.

The Performance Dashboard includes reports on:

• Access to a MySQL server for executing sample queries.
• Familiarity with MySQL tools like EXPLAIN for query analysis.

Indexes are crucial for speeding up data retrieval operations. They work like a table of contents in a book, allowing the database to find data quickly without scanning the entire table.

You can set the isolation level for the current session or globally to affect all new connections.
