Notes

Lightning Components
A Lightning component is a compact, configurable, and reusable element that you can add to a Lightning page in the Lightning App Builder.
Lightning Page Types
App Page
Use an app page to create a home page for a third-party app that you can add directly into the Salesforce mobile app and Lightning Experience navigation menus. Your users then have an app home page where they can quickly access the most important objects and items.
Home Page
Create Home pages with features relevant to specific types of users, and assign the customized pages to different apps or app-and-user-profile combinations. Custom Home pages are supported in Lightning Experience only.
Record Page
With a record page, you can create a customized version of an object’s record page, tailoring it to your users’ needs. Custom record pages are supported in Lightning Experience and in the Salesforce mobile app.
