Are there any best practices for managing unique constraints in PHPmyadmin?

When managing unique constraints in PHPMyAdmin, it is important to ensure that duplicate entries are not allowed for specific columns in a table. One best practice is to define unique constraints at the database level to enforce data integrity. This can be done by adding a UNIQUE constraint to the column(s) that should not have duplicate values.

// Example SQL query to add a unique constraint to a column in PHPMyAdmin
ALTER TABLE table_name
ADD CONSTRAINT constraint_name UNIQUE (column_name);
