Introductions are fun, and this time around, we will be scratching the surface a little more to understand how to model your Salesforce Data.

What are Objects in Salesforce
- Salesforce Objects are like DB tables
- We use them to store persistent data
- It has additional properties and features.
Standard vs. custom objects
| Standard Objects | Custom objects |
| API names of standard objects do not end with __c | API names of standard objects do not ends with __c |
| API names of custom objects end with __c | Example of the custom object name is Employee__C or Department__c |
| Limited Customization | Fully Customizable |
| Examples of standard objects are Account, Contact & User | Standard Objects are out of the box: The objects provided by Salesforce are called standard objects. |
Lookup VS Master detail
| Lookup | Master Detail |
| This is a parent-child relationship. | The detail object is deleted when the Parent is deleted. This links two objects together. |
| Both linked records have independent sharing and security settings. | The detail record inherits the sharing and security settings of its master record. |
| Roll-up summary fields are not available on lookups. | Parents can have Roll-Up Summary fields. |
| Reference to linked records is optional. | The detail record must have a Master record reference. |
| Up to 40 lookups on a custom object (child can have up to 40 parents) | You can have 2 master details on an object. |
| No Cascade delete | Cascade delete |
