Salesforce Interview Questions and Answers
1) What is App in Salesforce?
Ans: An app is a group of tabs that work as a unit to provide functionality. Users can switch between apps using the Force app drop-down menu at the top-right corner of every page.
You can customize existing apps to match the way you work, or build new apps by grouping standard and custom tabs.
Navigation to create app in Sales force: Setup ->Build ->Create->App-> Click on new and create your application according to your requirements.
2) What is object in Salesforce? Ans: Custom objects are database tables that allow you to store data specific to your organization in Salesforce You can use custom objects to extend Salesforce functionality or to build new application functionality. Once you have created a custom object, you can create a custom tab, custom related lists, reports, and dashboards for users to interact with the custom object data. You can also access custom object data through the Force API. Navigation to create object in sales force: Setup->Build->Create->Object-> Click on new object and create object according to your requirement.
3) How many relationships included in SFDC & What are they? Ans: We are having two types of relationships, they are Lookup Relationship Master-Detail Relationship
4) What is a “Lookup Relationship”? Ans: This type of relationship links two objects together, Upto 25 allowed for object Parent is not a required field. No impact on a security and access.No impact on deletion. Can be multiple layers deep. Lookup field is not required.
5) What is “Master-Detail Relationship”? Ans: Master Detail relationship is the Parent child relationship. In which Master represents Parent and detail represents Child. If Parent is deleted then Child also gets deleted. Rollup summary fields can only be created on Master records which will calculate the SUM, AVG, MIN of the Child records. Upto 2 allowed for object. Parent field on child is required. Access to parent determines access to children. Deleting parent automatically deletes child. A child of one master detail relationship cannot be the parent of another. Lookup field on page layout is required.
6) How can I create Many to Many relationship? Ans: Lookup and Master detail relationships are one to many relationships. We can create many to Many relationship by using junction object. Junction object is a custom object with two master detail relationships.
7) A custom object contains some records, now my requirement is to create field in this object with master detail relationship. Can we create master detail relationship in this case? Ans: No, directly we cannot create master details relationship if custom object contains existing records. Following are the steps to create to create master-detail relationship when records are available in custom object.First create field with lookup relationship. And then associate look field with parent record for every record. Next change the data type of the field from look up to Master detail.
8) List examples of custom field types? Ans: Text, Pick list, Pick list (multi select), Date, Email, Date/Time, Date, Currency, Checkbox, Number, Percent, Phone, URL, Text Area, Geolocation, lookup relationship, master detail relationship etc…..
9) What is TAB in Salesforce? Ans: Tab is a user interface component to user creates to display custom object data. There are three type of tabs.
10) Does user can create insert their own custom logo, while creating their own custom applications? Ans: Yes user can upload their custom logo in documents and then they choose that logo for organization.
11) List things that can be customized on page layouts? Ans: We can customize different things on page layout like, Fields, Buttons, Custom Links and Related Lists. We can also create sections.
12) What is a “Self Relationship”? Ans: Self Relationship is a lookup relationship to the same object. Suppose let’s take an object “Merchandise”. Here we can create relationship in between the Account to Account (same object) object. That is called “Self Relationship”.
13) What are the main things need to consider in the “Master-Detail Relationship”? Ans: Record level access is determined by the parent, Mandatory on child for reference of parent, cascade delete (if you delete the parent, it can cascade delete the child).

15) What is Wrapper class? Ans: A Wrapper class is a class whose instances are collection of other objects. It is used to display different objects on a Visual Force page in same table.
16) What is Difference between SOQL and SOSL? Ans: SOQL(Salesforce Object Query Language):
17) What is difference insert() and database .insert() ?

Administrator creates the permission set having edit and creates operation on custom object and assign to that user.
31) What is manual sharing? Ans: Manual sharing is to share a record to a particular user manually. Go to detail page of record and click on manual sharing button and assign that record to other user with Read or Read/Write access.

Using Eclipse IDE we can create the Visulaforce page and write the code.
48) What are Apex Governor Limits? Ans: Governor Limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.
49) What are the types of sandboxes and what is the difference? Ans: Salesforce gives us the ability to create multiple copies of organization in separate environments for a variety of purposes, such as testing and training,without compromising the data and applications in Salesforce production organization.

If we do not see the data export feature, contact salesforce support to have the Data Export Service activated. The following path will tells us how to schedule the export Click Setup -> Data Management -> Data Export -> Schedule Export Note: 1. we have 48 hours from the time we are notified the backup is available to download the backup file. 2. The email notification for backups goes to the email address in Salesforce of the person logged in who schedules the backup
