Event-driven integration patterns that decouple producers and consumers and make change propagation more flexible.
Event-driven patterns are often better than synchronous request-response for loosely coupled business flows.

Intro
Event-driven patterns are often better than synchronous request-response for loosely coupled business flows.
Use this page to understand Platform Events and CDC at definition level, decision level, and implementation level so the concept becomes useful in design discussions, interviews, certification study, and day-to-day Salesforce delivery.

Deep Dive
In real Salesforce work, Platform Events and CDC usually becomes important when teams move beyond feature recall and need to make decisions about scale, governance, user experience, and operational ownership. Strong implementations connect the concept to business process design, user outcomes, release discipline, and the limits of the surrounding platform.
Platform Events publish business events, while CDC communicates data change events for subscribed consumers.
When you study Platform Events and CDC for interviews or certifications, focus on the tradeoffs. Employers and architects rarely care only about the label. They want to know when the pattern fits, what risks it introduces, how it behaves under change, and how you would explain the decision clearly to non-technical stakeholders.
A good learning habit is to connect Platform Events and CDC to adjacent Salesforce concerns: data model design, security boundaries, automation interactions, testing, deployment impact, and supportability after launch. That broader context is what turns memorized notes into implementation judgement.

Execution Path
Step by Step
Start by defining what Platform Events and CDC is solving in the business process, not only what feature or tool is available.
Map the surrounding data, users, permissions, and dependencies so the scope of Platform Events and CDC is clear before configuration or code begins.
Choose the Salesforce pattern that best fits the requirement, then document why that choice is more appropriate than the main alternatives.
Test Platform Events and CDC with realistic records, user personas, and edge cases so the behavior is validated under conditions that resemble production.
Review maintainability, monitoring, and handoff considerations so Platform Events and CDC stays understandable after launch and future releases.
