Salesforce is a fancy database

In this video I am going to explain Salesforce Database (Data Modelling) in depth in an interesting and fun way.
I have divided this video into 4 parts:
- What are objects in Salesforce?
- How many types of objects are there and What is the difference between Standard Object and Custom Object?
- What are in fields in Salesforce?
- How many types of fields are there and what is the difference between Standard Field and Custom Field?
