Overview of Using Application Composer

Use Application Composer to extend certain applications by creating fields, objects, and relationships between objects. Here are some of the changes you can make using this tool.

• Modify objects by adding new fields, or create entirely new objects.

• Create foreign key-based relationships between two objects.

• Modify user interface pages by exposing your newly created fields for an object, or create an entirely new work area for your custom objects.

• Expose object relationships on pages in the form of subtabs.

• Write application logic, such as triggers and validation rules, for an object or for use across multiple objects.

• Implement functional and data-level security for custom objects.

• Enable custom objects for reporting by creating custom subject areas.
