You can separate business logic in Apex by implementing enterprise patterns like the Domain layer for record rules and the Service layer for orchestration, ensuring growing codebases remain maintainable and testable.

The best way to centralize SOQL queries in Salesforce Apex is by using a Selector layer, which removes ad-hoc queries from business logic and promotes reuse across your application.

You manage atomic DML transactions across multiple objects in Apex by applying the Unit of Work pattern, which owns transaction boundaries and commits cross-object operations like Account and Opportunity updates together.

You need enterprise patterns for Apex trigger logic when your Salesforce project grows beyond a handful of developers or classes, encounters complex trigger logic, or requires multi-object orchestration like upgrades and service workflows.

Yes, you can use FFLIB with lightweight implementations; the architecture supports both FFLIB and lightweight Unit of Work integration to ensure transaction safety and testability without requiring a strict framework dependency.

Migrating complex trigger logic into Domain classes encapsulates record-level business rules, making trigger behavior easier to test, reuse, and maintain while reducing duplicated logic across your Apex codebase.
