Mastery involves defining custom events, handling large-scale event processing, and implementing durable subscriptions. Proper integration design reduces latency, prevents data inconsistency, and promotes asynchronous processing to enhance overall system responsiveness.

External system error handling is pivotal. Developers should design retry mechanisms, error queues, and logging frameworks to handle failed API calls gracefully. Ensuring idempotency in integration processes prevents data duplication or corruption, which is critical for maintaining enterprise-grade reliability.

Data Modeling and Complex Relationships

Salesforce data architecture is deceptively intricate. Beyond standard objects, Platform Developer II candidates must comprehend custom objects, junction objects, and polymorphic relationships. Understanding master-detail versus lookup relationships, hierarchical structures, and roll-up summary calculations enables developers to model data efficiently for complex business requirements.

Advanced SOQL queries and relationship traversals form another layer of expertise. Developers must optimize queries to retrieve related records, avoid nested loops, and leverage aggregate functions effectively. Indexing, selective filters, and query plan analysis are essential to prevent performance degradation in large datasets.

Moreover, data integrity and validation require meticulous attention. Triggers, validation rules, and formula fields must work harmoniously to enforce business rules without creating conflicts or circular dependencies. Auditing, historical tracking, and sharing settings add additional dimensions to consider, ensuring secure, compliant, and scalable data management.
