Hello Shradha

You can use SOAP API  when you need to create, retrieve, update, or delete records. You can also use SOAP API to perform searches and much more. Use SOAP API in any language that supports web services. For example, you can use SOAP API to integrate Salesforce with your org's ERP and finance systems.

Hello Sanjana

Aura is an open-source UI framework built by Salesforce for developing dynamic web apps for mobile and desktop devices.To build lightning components in salesforce lightning we use the Lightning component framework. The lightning component framework is not different from the Aura framework rather it is a subset of the Aura framework. The Lightning Component framework is built on the open-source Aura framework. However, the open-source Aura framework has some features that aren’t available to Lightning Component framework.

Thank you.

The authorization process verifies whether you have permission to access the data you want from the server. When you send a request, you often have to include parameters to ensure the request has permission to access and return the data you want. Postman provides authorization types that make it easy for you to handle authentication protocols in Postman native apps.

OAuth 2.0 is an authorization type that enables you to approve an application that contacts another application for you without exposing your password.

Salesforce Apex Property is similar to a variable, they can validate data before a change is made; they can prompt an action when data is changed, such as altering the value of other member variables; or they can expose data that is retrieved from some other source, such as another class.

Thank you.

Hello Prachi

Coarse-grained -A few objects hold a lot of related data that's why services have broader scope in functionality. larger components than fine-grained, large sub components. Simply wraps one or more fine-grained services together into a more coarse­-grained operation.
Fine-grained - More objects each holding less data that's why services have more narrow scope in functionality. smaller components of which the larger ones are composed, lower ­level service

It is better to have more coarse-grained service operations, which are composed by fine-grained operations

Thank you.

Hi sanjana

You can have n number of triggers on single objects, but best practice is to have all trigger event operations into the singe trigger with the if conditions.
