"To implement business rules using Apex triggers, I would create a trigger that executes before or after a specific event, such as a record being created, updated, or deleted. Within the trigger, I would write the code to enforce the business rules. For example, I might validate that certain fields are populated correctly, update related records based on the values in the trigger record, or send a notification to a user if a specific condition is met. It's crucial to write the trigger in a bulk-safe manner, using collections to process multiple records at once and avoiding SOQL queries and DML operations inside loops. Additionally, I would implement proper exception handling to gracefully handle any errors that occur during the trigger's execution."
