  Apex Class

An Apex class is a unit of code that can be used to perform tasks such as manipulating data, calling web services, and creating custom objects. Apex classes are written in the Apex programming language, which is a strongly typed, object-oriented language.

Apex classes can be used to create custom objects, fields, and triggers. They can also be used to create custom settings, pages, and components. Apex classes can be called from Visualforce pages, Lightning components, and other Apex classes.

Component

A component is a reusable piece of code that can be used to create Visualforce pages and Lightning components. Components are defined in XML files and can be used to create custom buttons, links, and other elements.

Components can be nested inside other components, and they can be reused multiple times in a single page or component. Components can also be exported and imported, which makes them easy to share with other developers.

Custom Object

A custom object is a type of object that can be created in Salesforce to store data. Custom objects can be used to store data about customers, products, orders, or any other type of information.

Custom objects can be related to each other, and they can be used to create custom fields, relationships, and validation rules. Custom objects can also be used to create custom views, reports, and dashboards.

Data Extension

A data extension is a type of object that can be used to store large amounts of data. Data extensions are similar to custom objects, but they are not associated with a specific Salesforce organization.

Data extensions can be used to store data that is not related to any specific Salesforce object, and they can be used to create custom reports and dashboards. Data extensions can also be used to import and export data from Salesforce.

Field

A field is a column of data that is stored in a custom object. Fields can be used to store text, numbers, dates, or any other type of data.

Fields can be required or optional, and they can be used to create custom validation rules. Fields can also be used to create custom relationships between custom objects.

ListView

A list view is a view of a custom object that can be used to display a list of records. List views can be customized to show the fields that you want to see, and they can be used to filter, sort, and group records.

List views can also be used to create custom reports and dashboards. List views can be shared with other users, and they can be exported to Excel or PDF files.

Page

A page is a type of object that can be used to create a user interface in Salesforce. Pages can be used to create custom forms, pages, and reports.

Pages can be customized to look and feel the way you want, and they can be used to add custom functionality to Salesforce. Pages can also be shared with other users, and they can be exported to HTML or PDF files.

Profile

A profile is a set of permissions that is assigned to a user. Profiles can be used to control what users can see and do in Salesforce.

Profiles can be assigned to individual users, or they can be assigned to groups of users. Profiles can also be used to create custom roles for users.

Record Type

A record type is a type of object that can be used to create different versions of a custom object. Record types can be used to control what fields are displayed on a custom object, and they can be used to create custom validation rules.

Record types can also be used to create custom relationships between custom objects.

Schema Object

A schema object is a type of object that represents a table in the Salesforce database. Schema objects can be used to view the structure of the Salesforce database, and they can be used to create custom objects and fields.

Schema objects can also be used to create custom relationships between custom objects.

Trigger

A trigger is a piece of code that is executed when a record is created, updated, or deleted. Triggers can be used to add, update, or delete records, and they can be used to send emails or perform other actions.

Triggers can be used to enforce data integrity, and they can be used to automate tasks.

Visualforce Page

A Visualforce page is a type of page that can be used to create a user interface in Salesforce. Visualforce pages can be used to create custom forms, pages, and reports.

Visualforce pages can be customized to look and feel the way you want, and they can be used to add custom functionality to Salesforce. Visualforce pages can also be shared with other users, and they can be exported to HTML or PDF files.
