 What are Governor Limits?2

 What are Governor Limits ?2
• Salesforce works on the concept of multi-tenant architecture
where the resources are shared across multiple clients.
• To make sure no one client monopolize the shared resources,
Apex run-time engine strictly enforces governor limits.
• If your Apex code ever exceeds that limit, the expected governor
issues a run-time exception that cannot be handled.
• Hence as a Salesforce developer, you have to be very careful
while developing your application.
MULTI-TENANTARCHITECTURE
Common
Application
for all Clients

 What is a sandbox org?

 Can you edit an apex trigger/ apex class in production environment?
 Can you edit a Visualforce page in production environment?4

 Can you edit an apex trigger/apex class in production environment?
 Can you edit a Visualforce page in production environment?4
• No, it is not possible to edit apex classes and triggers directly on production environment.
• It can be done only on Developer Edition & Sandbox. To deploy it in production, a user with Author Apex permission must
deploy the triggers and classes using deployment tools.
• However, Visualforce pages can be created and edited in both sandbox and in production.
• Only if the page has to do something unique (different values), it would have to be developed via Sandbox.

 What is the use of writing sharing rules?
 Can you use sharing rules to restrict data access?8

 What is the use of writing sharing rules?
 Can you use sharing rules to restrict data access?8
➢ By default, all users in your organization will have organization-wide-default sharing settings of either Public Read Only
or Private.
To give access to more records, which users do not own, we write sharing rules.
Example: Sharing rules are used to extend sharing access to users in public groups or roles.
Hence, sharing rules are not as strict as organization-wide default settings. They allow greater access for those users.
➢ No, we cannot use sharing rules to restrict data access. It is only used for allowing greater access to records.

 What is a bucket field in reports?10
• Bucketing lets you quickly categorize report records without creating a formula or a custom field within Salesforce.
• They can be used to group, filter, or arrange report data.
• When you create a bucket field, you need to define multiple categories (buckets) that are used to group report values.
• Earlier, we had to create custom fields to group or segment certain data.

 What are dynamic dashboards?
 Can dynamic dashboards be scheduled?11

 What are dynamic dashboards?
 Can dynamic dashboards be scheduled?11
➢ Dynamic dashboards are used to display information tailored to a specific user, while a normal dashboard shows data only
from a single user's perspective.
You can use dynamic dashboards when you want to show each user user-specific data, such as their personal quotas and
sales, or number of case closures, or leads converted, etc.
You can also use a normal dashboard when you want to show regional or organization-wide data to a set of users, such as a
region's sales, or a support team's performance on case closures.
➢ No we cannot schedule a dynamic dashboard.

relationship?15

 Explain the term “data skew” in Salesforce.16

 Explain the term “data skew” in Salesforce.16
➢ When more than 10,000 records of an object are owned by one single user, we call that condition ownership data skew.
➢ When such users perform updates, performance issues will be encountered because of “data skew”.
➢ This happens when a single user/ members of a single role own most of the records for a particular object.

 Explain skinny table.

 How can you expose an Apex class as a REST WebService in
Salesforce?31

Salesforce?31
➢ Use global classes and a webservice callback method.
➢ Invoking a custom Apex REST Web service method always uses system context. Consequently, the current user's credentials
are not used, and any user who has access to these methods can use their full power, regardless of permissions, field-level
security, or sharing rules.
Developers who expose methods using the Apex REST annotations should therefore take care that they are not inadvertently
exposing any sensitive data.

Salesforce?31
global class AccountPlan {
webservice String area;
webservice String region;
//Define an object in apex that is exposed in apex web service
global class Plan {
webservice String name;
webservice Integer planNumber;
webservice Date planningPeriod;
webservice Id planId;
}
webservice static Plan createAccountPlan(Plan vPlan) {
//A plan maps to the Account object in salesforce.com.
//So need to map the Plan class object to Account standard object
Account acct = new Account();
acct.Name = vPlan.name;
acct.AccountNumber = String.valueOf(vPlan.planNumber);
insert acct;
vPlan.planId=acct.Id;
return vPlan;
} }

 What is the use of “@future” annotation?41

 What is the use of “@future” annotation?41
➢ Future annotations are used to identify and execute methods asynchronously.
If the method is annotated with “@future”, it will be executed when Salesforce has available resources.
➢ Ex:- Use it while making asynchronous web service callout to an external service.
Without the annotation, the Web service callout is made from the same thread that is executing the Apex code, and no
additional processing can occur until the callout is complete (synchronous processing).
