Frequently Asked Questions about Salesforce-apex
What is Salesforce-apex?
Salesforce Apex is a strongly typed, Java-like programming language used to implement custom business logic on the Salesforce Platform. It provides server-side execution within the multi-tenant Salesforce environment, enabling automation, integrations, transactional operations, and advanced customization beyond declarative tools.
What are the primary use cases for Salesforce-apex?
Trigger-based automation for complex business rules. Custom REST/SOAP services for integrations. Batch and async processing for high-volume data jobs. Custom Lightning Web Component (LWC) backend controllers. Transactional orchestration and advanced validation logic
What are the strengths of Salesforce-apex?
Fully native to Salesforce - high performance and strong ecosystem integration. Transaction-safe with rollback and savepoint APIs. Enterprise-ready integration patterns supported out-of-the-box. Strong metadata-driven development experience. Pairs well with declarative automation for hybrid workflows
What are the limitations of Salesforce-apex?
Governor limits require careful design and optimization. Cannot interact directly with external systems without callouts. Multi-tenant architecture restricts unrestricted resource use. Debugging large-scale automation requires strong logging discipline. Deployment requires test success - higher initial development overhead
