Data Modelling— Admin Beginner

There are standard objects, custom objects, external objects, platform events, and BigObjects, but mainly we will focus on standard and custom objects.

1. Standard: It is provided by Salesforce like Accounts, Contact, Lead, etc.

2. Custom: It is defined by you according to business requirements.

Objects are containers for your information, Salesforce provides some functionality with it like page layout for the user interface.

Object:

● Think of it like an object of a Class(not the wholesome).

● It consists of different Fields.

● When you want to see objects in Tab, you need to add them in the Tab section.

e.g: Property is an Object which has a Name, Address, Offer and Price as a Field

Fields

● Attribute of an object like a Name, etc.

● Field has Singular and Plural Name.

● Custom Field API_name end with `__c` to denote it as a custom field.

Object Relationship

1. Lookup Relationships

● Relationships between 2 Objects.

● Relationships can be one-to-one or one-to-many.

2. Master-Detail Relationships

● It is like a parent who has control over their child, who can take care(view) the child.

● e.g: A Owner wants to give/delete an offer on his property so, you can see here Property is a Parent and Offers is its children. In this scenario, If the owner deletes the property, the offer will also get deleted.

3. Hierarchical Relationships

● A special type of lookup relationship.

● It is only available for User Object.

● You can use them for things like creating management chains between users.

Objects in lookup relationships usually work as stand-alone objects but in the master-detail relationship, the detail object doesn’t work as a stand-alone, It is completely dependent on the Master.
