Apex Triggers
Apex Triggers are a Salesforce-specific programming feature that allows developers to execute custom Apex code in response to specific events on Salesforce records, such as before or after insert, update, delete, or undelete operations. They are used to enforce business logic, automate processes, and integrate with external systems directly within the Salesforce platform. Triggers run on the server-side and can manipulate data or trigger other actions based on changes to Salesforce objects.
Developers should learn Apex Triggers when building custom applications on the Salesforce platform to automate complex business workflows, ensure data integrity, and extend standard Salesforce functionality. They are essential for scenarios like validating data before saving, updating related records automatically, or syncing data with external APIs in real-time. Use cases include enforcing custom validation rules beyond standard validation, logging changes for audit trails, and implementing complex calculations that depend on record updates.
