To create a 1 to 1 relationship in Salesforce, use a lookup field on the child object pointing to the parent object.

• Create a lookup field on the child object that references the parent object.

• Ensure that the lookup field has a unique constraint to enforce the 1 to 1 relationship.

• Use validation rules or triggers to prevent multiple child records from being linked to the same parent record.

Fetching data from table in Apex

I would develop a calculator in Python using basic arithmetic operations and GUI libraries.

• Use Python's built-in arithmetic operators (+, -, *, /) to perform calculations.

• Use a GUI library like Tkinter or PyQt to create a user-friendly interface.

• Implement error handling to prevent invalid inputs and division by zero.

• Consider adding additional features like memory functions or scientific notation.

• Test the calculator thoroughly to ensure accurate results.

Security measures in Salesforce include user authentication, data encryption, IP restrictions, and field-level security.

• User authentication methods like password policies, two-factor authentication, and single sign-on are crucial for securing access to Salesforce.

• Data encryption ensures that sensitive information is protected both at rest and in transit.

• IP restrictions can be set to control access to Salesforce from specific locations or networks.

• Field-level security allows a...read more

Queueable is used for asynchronous processing while future apex is used for executing code in a separate thread.

• Queueable is used for complex, long-running processes that can be split into multiple jobs.

• Future apex is used for short, quick processes that need to be executed in a separate thread.

• Queueable jobs can be chained together to run in a specific order.

• Future apex methods are limited in terms of governor limits compared to Queueable jobs.

• Use version control system like Git to manage code changes

• Automate build process using tools like Jenkins

• Run automated tests to ensure code quality

• Deploy to different environments using tools like Docker and Kubernetes

• Monitor and log application performance using tools like Splunk

• Use continuous feedback to improve the process

I would develop a calculator in Python.

• I would use the built-in math library for mathematical operations.

• I would use the Tkinter library for creating a GUI.

• I would define functions for each operation (addition, subtraction, multiplication, division, etc.).

• I would handle errors and exceptions to ensure the calculator functions properly.

• I would test the calculator thoroughly to ensure accuracy.

Interfaces in Salesforce provide a way to define a contract for classes to implement specific methods and behaviors.

• Interfaces define a set of methods that a class must implement

• Interfaces can be used to achieve polymorphism in Apex

• Interfaces can be used to enforce a common behavior across multiple classes

• Interfaces can be used to create loosely coupled code

• Examples of interfaces in Salesforce include Database.Batchable, Messaging.SendEmailResult, and HttpCalloutMock

Apex context variables hold different values based on the scenario in Salesforce development.

• Trigger.new and Trigger.old contain new and old versions of records in trigger context

• System.isBatch() returns true in batch context

• System.isFuture() returns true in future method context

• System.isScheduled() returns true in scheduled job context

CPU error in Apex

• Check for infinite loops or recursive calls

• Reduce the number of SOQL queries and DML statements

• Optimize code to reduce CPU usage

• Consider using asynchronous processing

• Use governor limits to avoid exceeding CPU time limit

There are unlimited reports in Salesforce (SF) as users can create custom reports based on their needs.

• Users can create custom reports using Salesforce Report Builder.

• Reports can be based on various objects and criteria.

• Reports can be scheduled to run at specific times and emailed to users.

• Reports can be used to analyze data and make informed business decisions.

Lookup relationships are associations between two objects in Salesforce, where one object has a reference to another object.

• Lookup relationships are used to create a link between two objects.

• They are defined by creating a lookup field on one object that references the other object.

• Lookup relationships can be one-to-one or one-to-many.

• They enable data sharing and linking between related records.

• For example, a Contact object can have a lookup relationship with an Account object...read more
