How can the performance issues related to inserting or updating data in Nested Sets be mitigated in a PHP application?

Performance issues related to inserting or updating data in Nested Sets can be mitigated by using transactions to group multiple insert or update operations together. This can reduce the number of times the database needs to be updated and improve overall performance.

// Begin a transaction
$pdo->beginTransaction();

// Perform multiple insert or update operations

// Commit the transaction
$pdo->commit();
