Apex is a proprietary programming language used in Salesforce for custom development, business logic, and integration with external systems. It is a powerful tool that enables developers to extend and customize Salesforce functionality beyond its native capabilities.
When should you use Apex?
A. Adding visual elements to the UI: This is not a valid use case for Apex. Visual elements can be added to the UI using declarative tools like Visualforce, Lightning Components, or the Lightning App Builder.
B. Attaching business logic to a data event (insert, update, delete): This is a valid use case for Apex. Apex triggers can be used to execute custom logic before or after records are inserted, updated, or deleted in Salesforce.
C. Augment behavior that applies when accessing data through the UI: This is a valid use case for Apex. Apex can be used to add custom validations, calculations, or business rules that apply when users interact with data through the UI.
D. Have logic that executes regardless of where the event originates (UI/S-Control/Web services API): This is a valid use case for Apex. Apex can be used to handle events from various sources, including UI interactions, S-Controls, or Web services API calls.
E. Want to process multiple records at the same time: This is a valid use case for Apex. Apex can be used to perform bulk data processing on large sets of records, such as mass updates, mass deletes, or complex calculations.
F. Use classes when coding Apex that will be used by other developers: This is a best practice when coding in Apex. Apex classes can be used to encapsulate business logic and data operations into reusable modules that can be called from other Apex code or external systems.
In summary, Apex is useful when custom business logic is required, especially when it is not achievable using declarative tools. Apex can also be used for data processing and handling events from various sources, as well as for encapsulating reusable code into classes.
