   PART 1

1.What is Multitenant Architecture ?

Ans:- An application model in which all users and apps share a single, common infrastructure and code base

2.What is Metadata-driven development model  ?

Ans:- An app development model that allows apps to be defined as declarative "blueprints," with no code required. Data models, objects, forms, workflows, and more are defined by metadata.

3.What is Force PlatformWeb Services API ?

Ans:- An application programming interface that defines a Web service that provides direct access to all data stored in Force Platform from virtually

any programming language and platform

4.What is Apex ?

Ans:- The world’s first on-demand programming language, which runs in the cloud on Force Platform servers

5.What is Visualforce ?

Ans:- A framework for creating feature-rich user interfaces for apps in the

Cloud

6.What are Force Platform sites ?

Ans:- Public websites and applications that are directly integrated with your

Salesforce organization—without requiring users to log in with a username and password

7.What is AppExchange directory ?

Ans:- A Web directory where hundreds of AppExchange apps are available to Salesforce customers to review, demo, comment upon, and/or

install. Developers can submit their apps for listing on the AppExchange directory if they want to share them with the community.

8.What is the difference between Native components and Composite Components ?

Ans:- One way to split up the work is to look at which requirements can be implemented by using just the point-and-click tools of the platform and which requirements must be implemented by leveraging other Web applications. The former method, which uses native components, is typically fast and simple to use, requiring only point-and-click setup rather than more traditional coding. The latter method, which uses composite components, give us more control and flexibility in what we do but requires more work.

 

The following diagram shows how features implemented with each method are created, split out by their user interface layer, business logic, and data model.

9.Name some Native Components ?

Ans:-

    Custom objects

    Security and sharing rules

    Workflow and approval processes

    Custom reports and dashboards

10.What are Custom Objects ?

Ans:- Custom objects are the native components that model the data we need to store in our application. Similar to a database table, a custom object is composed of several fields that store information such as a job applicant's name, or the maximum salary for a particular position.However, unlike traditional database tables, we don't need to write any SQL in order to create custom objects.We can simply point and click in the platform to create as many objects as we need.

11.What is a database ?

Ans:- A database is an organized collection of information.

12.What is a database table ?

Ans:- A database table stores information about a single type of person, thing, or concept—such as a job position. In the Force Platform, we use the term object here

13.What is a database row or record ?

Ans:- A database row, or record in Force Platform terms, represents a single instance of an  object—such as the SW Engineer position.

14.What is a field ?

Ans:- A field stores a particular piece of information on a record.

15.What are Relationships ?

Ans:- Relationships define the connection between two objects, and objects are related to each other through the use of common fields.

16.When do you Roll-up Summary fields ?

Ans:-

Use roll-up summary fields to display the sum, minimum, or maximum

value of a field in a related list, or the record count of all records listed in a related list.

17.What are the different types of Picklists and what is the difference between the  two ?

Ans:-

Picklists come in two flavors: a standard picklist, in which a user can select only one option, and a multi-select picklist, in which a user can select multiple options at a time. For the purposes of our Position object, we need to define standard picklists for a position's location, status, type of job, functional area, and job level.

 

18.What are field dependencies ?

Ans:-

Field dependencies are filters that allow us to change the contents of a picklist based on the  value of another field. For example, rather than displaying every value for Country in a single  picklist, we can limit the values that are displayed based on a value for another field, like  Continent. That way our users can find the appropriate country more quickly and easily.

19.What is the difference between controlling and dependent fields ?

Ans:-

Picklist fields can be either controlling or dependent fields. A controlling field controls the  available values in one or more corresponding dependent fields. A dependent field displays  values based on the value selected in its corresponding controlling field.For example, the Continent picklist is the controlling field, while the Country picklist is the dependent field.

 20.What are custom formula fields ?

 Ans:-

Just as you can use a  spreadsheet program like Microsoft Excel to define calculations and metrics specific to your  business, we can use custom formula fields to define calculations and metrics that are specific  to the application
