List different types of objects in Salesforce?

Objects are a crucial part of salesforce as they provide a structure so that you can store the data and is similar to a database table.

There are mainly three types of objects in salesforce-

• Standard Objects- These objects are provided by the Salesforce platform itself and can’t be deleted and truncated. These include contact, campaign, accounts, opportunity, etc.
• Custom Objects- Custom objects are created by the users according to their business processes and needs and can be deleted and truncated.
• External Objects- They are somewhat similar to custom objects and allow users to map the data which is stored outside the salesforce organization.
