2. Try not to use SOQL or DML operations in the loop.
3. Try to bulkify the code and helper methods.
4. Query large data sets.
5. Use Batch Apex if we want to process 50,000 records.
6. Streamline various triggers on the same object.

What happens if an operation in code exceeds a governor limit?

Because Apex runs in a multitenant environment, the Apex runtime engine strictly enforces limits to ensure that runaway Apex code or processes don’t monopolize shared resources. If some Apex code exceeds a limit, the associated governor issues a runtime exception that cannot be handled.

What happens when Governor limits in Salesforce?
