Definition and purpose of Apex Triggers:
Here’s a point-wise explanation of the definition and purpose of Apex Triggers:
Definition:
Apex Triggers are blocks of code that are executed automatically in response to specific events in Salesforce, such as insert, update, and delete operations on records.
Purpose:
The main purpose of Apex Triggers is to automate custom business logic in Salesforce, such as enforcing data integrity rules, updating fields, sending notifications, and more.
Custom Business Logic:
Triggers allow developers to automate custom business logic, such as enforcing data validation rules, updating fields, and sending notifications, without requiring manual intervention.
Record-level Automation:
Triggers operate at the record level, allowing developers to automate actions that should occur when a specific record is inserted, updated, or deleted.
Event-driven:
Triggers are event-driven, meaning that they are triggered by specific events, such as the creation or modification of a record, and automatically execute the logic defined in the trigger code.
Increases Productivity:
By automating common tasks, Apex Triggers can help increase productivity and reduce the likelihood of manual errors.
Enforces Data Integrity:
Triggers can be used to enforce data integrity rules, such as ensuring that certain fields are populated before a record is saved, or that certain conditions are met before a record can be deleted.
