Four pillars of HTML web components are Import, Template, Custom Element, Shadow DOM.

Auto-Response Rule: It automatically sends a personalized email response to customers based on each case's details. For example, you can send an automatic reply to customers to let them know someone at your company received their inquiry.

Types of event:

• Component Event: It is handled by the component itself or a component that instantiates or contains the component. It helps in passing values between two independent events (without parent-child relationship). It behaves just like a broadcast message.
• Application Event: It is handled by all components that are listening to the event. These events are essentially a traditional publish-subscribe model. This event is required in order to pass values from child components to parents.

@AuraEnabled:

• This annotation enables lightning components to access Apex methods and properties.
• It is overloaded and is used for two separate and distinct purposes.
• It is used on Apex class static methods to make them accessible as remote controller actions in your Lightning components.

Quotas: It is used to set target sales goals for forecast users. And also it can allow organizations to establish greater accountability for meeting sales expectations. Users with the appropriate permission can set their individual quota. Salesforce admins and users with the appropriate permission can edit any quota and managers can change the quotas of users who report directly to them in the role hierarchy.

[Shweta]

Benefits of using the lightning component framework:

• Rich component ecosystem and faster development
• Performance: The client calls the server only when absolutely necessary and the server only sends data that is needed by the user to maximize efficiency. The framework uses JSON to exchange data between the server and the client.
• Event-driven architecture: It uses event-driven architecture for better decoupling between components.
• Compatible with all Devices and Browsers: This framework supports the latest browser technologies which will make your app and pages compatible with all browsers.

Custom Metadata: It is customizable, deployable, packageable, and upgradeable application metadata. First, you create a custom metadata type, which defines the form of the application metadata then you build reusable functionality that determines the behavior based on metadata of that type.

There are four different types of sandbox available in Salesforce:

• Full Sandbox
• Developer Sandbox
• Developer Pro Sandbox
• Partial Data Copy Sandbox

[Shweta]

Sandbox is a copy of the production organization. You can create multiple copies of the organization that can be developed like one copy for development, another for testing and training and this can be done without any compromise of data in the production organization. It allows you to perform custom development and track quality assurance. When Salesforce rolls out new updates, you can test them out before applying them to your production organization. That way, nothing will be permanently changed before you know exactly what it does.

JSON Class: It contains methods for serializing Apex objects into JSON format and deserializing JSON content that was serialized using the serialize method in this class. JSON has a smaller footprint than XML, which means it can be transmitted and parsed faster than XML.

[Shweta]

Business Process: It enables you to display different picklist values for users based on their profiles. This type extends the Metadata metadata type and inherits its fullName field. A Business Process is the stage values assigned to an opportunity record type.

Governor limits for batch Apex:

• Only one batch Apex job’s start method can run at a run time.
• Up to 5 queued or active batch jobs are allowed for the apex.
• The maximum number of batch apex method executions per a 24 hour period is 2,50,000.
• The batch apex start method can have up to 15 query cursors open at a time per user.
• A maximum 0f 50 million records can be returned in the Database.QueryLocator object.
• The Start, Execute and Finish method can implement up to 10 callouts each.

SFTP: SSH File Transfer Protocol. The FTP server uses SFTP as a secure and flexible file transfer protocol. When you use SFTP, Marketing Cloud creates a folder on the FTP server for your organization. This folder is for your organization only, so use a special user ID and password to access the folder.

We can use the SFTP folder to import data into lists and data extensions in Marketing Cloud.

[Shweta]

CornTrigger: It is an object in salesforce which contains schedule information for a scheduled job. It holds the CronExpression, NextFireTime, LastFireTime, StartTime, End Time, status, etc. It is used to query scheduled jobs in your organization.

Example:-

List<CronTrigger> jobs = [Select Id, State, NextFireTime From CronTrigger];
for(CronTrigger job : jobs)
{
System.debug(job);
}

SOAP API: It has been preferred for services within the enterprise and it involves downloading a WSDL file, Converting the WSDL files to regular classes and then invoking methods on those objects.
REST API: It has been preferred for services that are exposed as public APIs. You access rest API in the form of URL.

[Shweta]

A single static resource can be up to 5 MB in size, and an organization can have up to 250 MB of static resources.

Matrix Report: It can be used as the source report for dashboard components. Using this type of report for comparing related totals, especially if you have large amounts of data to summarize and you need to compare values in several different fields, or you want to look at data by date and by-product, person, or geography.

[Shweta]

Summary Report:

• It is similar to tabular reports, but also allow users to group rows of data, view subtotals, and create charts.
• It can be used as the source report for dashboard components.
• It is also used for a report to show subtotals based on the value of a particular field or when you want to create a hierarchical list.

[Shweta]

Tabular Report: It is the simplest and fastest way to look at data. It is used for creating lists of records or a list with a single grand total.

[Shweta]

Data loss caused due to the following reasons:

• Integration issues with 3rd party apps
• Accidental or malicious deletion of Salesforce data
• Data import gone wrong / Improper data mapping
• Improper developer coding
• SOQL mistake

Pardot: Pardot is a marketing automation platform that allows companies to find out their best leads, track marketing campaigns engagement and provide faster follow-ups and It is suited for B2B Marketing (Business-to-business).

<apex:actionfunction> : This component provides a support for invoking controller action methods directly from JavaScript code using an AJAX request. It must be a child of an <apex:form> component because binding between the caller and <apex:actionFunction> is done based on parameter order.

[Shweta]

Apex Callout: It enables you to tightly integrate your apex code with an external service and the callout makes a call to an external web service or sends an HTTP request from Apex code, and then receives the response.
It comes in two flavors :

• Web service callouts to SOAP web services:  It uses XML, and requires a WSDL document for code generation.
• HTTP callouts to services: It uses REST with JSON.

An app that can be built using Salesforce:

• Recruiting App
• Deliveries App
• Inspection App
• Employee Onboarding App
• Budgeting App
• Inventory App
• Project App
• Contract App
• Social Intranet App
• Clienteling App

[Shweta]

Salesforce App: It is a group of tabs that makes it easy for users to access a set of related features in the full Salesforce.com browser app. All the metadata such as Objects, Visualforce Pages, Classes, etc is independent of an app. It just helps to group things together visually.
