Here is some key point of our session.
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 |
| Standard Objects are out of box: The objects provided by Salesforce is called standard objects | Are user defined : The objects created by us are called custom objects |
| API names of standard objects does not ends with __c | API names of custom objects ends with __c |
| Limited Customization | Fully Customizable |
| Example of standard object are Account, Contact & User | Example of custom object name is Employee__C or Department__c |
Lookup VS Master detail
| Master Detail | Lookup |
| This is parent-child relationship | This links two objects together |
| Detail object is deleted when Parent is deleted | No effect on linked records |
| Parent can have Roll-Up Summary fields | Roll-Up Summary field are not available on lookups |
| Detail record must have Master record reference | Reference to linked record is optional |
| The detail record inherits the sharing and security settings of its master record. | Both linked records have independent sharing and security settings |
