## Standard Objects vs. Custom Objects in Salesforce

In Salesforce, both standard objects and custom objects are used to store data, but they differ significantly in their origins and functionalities.

Standard Objects
Pre-built objects: These are objects that come pre-packaged with Salesforce and are designed to store common business data, such as Accounts, Contacts, Leads, Opportunities, and Cases.
Default fields: Standard objects have a set of default fields that are essential for their respective business processes.
Customization: While you can customize standard objects by adding custom fields, modifying page layouts, and creating validation rules, you cannot delete or rename them.

Custom Objects
User-created objects: These are objects that you create to store information specific to your organization's unique needs.
Flexible design: Custom objects allow you to define your own fields, relationships, and validation rules to suit your specific requirements.
Complete control: You have full control over custom objects, including the ability to create, modify, and delete them.

Here's a table summarizing the key differences:

| Feature | Standard Objects | Custom Objects |
|---|---|---|
| Origin | Pre-built by Salesforce | Created by users |
| Fields | Default fields with limited customization | Customizable fields |
| Relationships | Predefined relationships | Customizable relationships |
| Deletion | Cannot be deleted | Can be deleted |
| Flexibility | Limited customization | Highly flexible |

When to use each:

Use standard objects: When the pre-built functionality of a standard object meets your needs.
Use custom objects: When you need to store data that is not covered by standard objects, or when you need to customize data storage to meet specific business requirements.

By understanding the differences between standard objects and custom objects, you can effectively model your data in Salesforce and optimize your business processes.
