Introductions are fun and this time around we will be scratching the surface a little more to understand how data can be modeled on Salesforce. In this session, we will learn about the difference between Standard and Custom Object, Different data types in Salesforce, and Lookup vs Master Details relationship.
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 |
