Salesforce interview questions, quiz and handbook in your Learning Dashboard
What you will learn
- Governor limits cap queries, DML and CPU per transaction.
- Triggers must handle up to 200 records at once.
- One trigger per object with a handler class keeps logic testable.
Programming on a shared platform
Salesforce runs many customers on shared infrastructure, so it enforces governor limits per transaction: a maximum number of SOQL queries, DML statements, CPU time and heap. Code that ignores them fails the moment real data arrives.
Good Salesforce development is therefore bulk-first: assume every trigger receives a list of records, never a single one.
