Study Notes

Developer Fundamentals

Use Opportunity.sobjectType.getDescribe().getRecordTypeInfos() to get a list of record types, and iterate through them until isDefaultRecordTypeMapping() is true.
@AuraEnabled annotation allows to create Apex classes that can be called from Lightning web components
public class CheckPaymentProcessor implements PaymentProcessor { public void pay (Decimal amount); } - This code implements the PaymentProcessor interface and creates a method named pay.
@TestVisible annotation makes a method accessible to the test class.
To create a currency input field that is viewable and editable only for users with the correct field level permissions use: <lightning-input-field field-name="salary_c"></lightning-input-field>.

Apex Fundamentals

Ensure that the Account object has a master-detail relationship to the Branch object.
Triggers fire multiple times during a transaction.
Duplicate rules are executed once all DML operations commit to the database.

Process Automation

Use Test.getStandardPriceBookId() to get the standard price book ID.
Use an aggregate function in a trigger on the Opportunity object to calculate a roll-up summary from a custom object that is not in a master-detail relationship.

User Interface

Use a Standard Controller with a Custom List Controller extension in order to allow users to edit multiple records at once.

Testing

Use the BISTest (SeeAllData=true) method allows access to the standard price book.

Salesforce Development Life Cycle

Full Sandbox is ideal to create the same configuration as the production org for a team of developers working on their individual orgs.
Ensure the PrimaryId_c custom field on the Candidate_c custom object is marked as an External Id.
Trigger execution can affect by before insert, after insert, before update, after update trigger events.
DML operations are going to be rolled back after debuging a flow is ended.

Lightning Web Components

fire() method is used to fire an event in Aura application events.
When using the Batchable interface the Apex governor limits are reset for each iteration of the execute() method.
To troubleshoot performance issues when a custom page loads, use System.debug().
Universal Containers can use Custom objects and fields, Roll-up summaries, and Relationships to build out the database layer for a Salesforce application.
Callouts to external systems are not executed when debugging a flow.
The developer should create a Screen-based flow to implement the functionality for a service agent to process damaged or stolen credit cards.
To create an account, the developer uses Account myAccount = new Account(Name = 'MyAccount'); to create an account object, then insert myAccount; inserts it into the database.
The loop using the do..while statement executes 9 times.
The loop creates 9 new accounts and inserts them into the database with names like 'New Account 1', 'New Account 2', etc.
There are 16 total accounts in the org, since the developer started with 5 and created 10 more.
The final account created is named New Account 10. The loop code increment the x variable up to 10 after each iteration. Therefore, the loop will execute 9 times (10 - 1 = 9), creating 9 new accounts.
