App Builder Platform-App-Builder Salesforce Study Notes

 NOT(ISBLANK(Job_Accepted__c)) && ISCHANGED(Hire_Date__c) is the validation formula that the app builder should use to meet the requirement of preventing changes to Hire Date after Job Accepted is entered. This formula will return TRUE if Job Accepted is not blank and Hire Date is changed, which will display an error message and prevent saving the record. The other formulas are not correct or valid.

The two considerations that should be made are: The Star records are all required to have an existing value in their Galaxy field. This is a prerequisite for converting a lookup relationship to a master-detail relationship. A lookup relationship is an optional relationship that links two objects together, but does not enforce referential integrity or cascade delete. A master-detail relationship is a required relationship that links two objects together and enforces referential integrity and cascade delete. To convert a lookup relationship to a master-detail relationship, all child records must have a value in their lookup field that references an existing parent record. The Galaxy object has fewer than two existing master-detail relationships. This is another prerequisite for converting a lookup relationship to a master-detail relationship. An object can have up to two master-detail relationships with other objects and can act as both the parent and child in different relationships. To convert a lookup relationship to a master-detail relationship, the parent object must have fewer than two existing master-detail relationships with other objects. The Galaxy object is required to contain existing roll-up summary fields is not a valid consideration, as it is not related to converting a lookup relationship to a master-detail relationship. 

For Universal Containers to understand the return on investment (ROI) for their latest advertising buy while using a private security model, the best recommendation is to use Campaign Hierarchies and Campaign statistics.

Campaign Hierarchies and Campaign Statistics: Campaign hierarchies allow Universal Containers to track the effectiveness and ROI of marketing efforts by grouping related campaigns (e.g., advertising buys) under a parent campaign and rolling up key metrics like responses, converted leads, and won opportunities. Campaign statistics provide detailed insights into individual and aggregate campaign performance, helping calculate ROI.

This method works well within a private security model since it respects existing sharing rules and access controls, ensuring that only authorized users can see the campaign data.

When Cloud Kicks needs to calculate summaries from child objects of a standard object declaratively, a few key considerations about master-detail relationships come into play. Master-detail relationships are critical in Salesforce when working with roll-up summary fields, which allow you to calculate values from child records.

Option B: An object can have up to two master-detail relationships.

Salesforce allows an object to have two master-detail relationships. This is important because if you want to aggregate child record data using roll-up summary fields, you need to have a master-detail relationship in place. Each master-detail relationship links a child object to a parent, and you can create roll-up summary fields on the parent object to summarize the child record data.
