Salesforce Data Types

A.

Salesforce supports various data types that are used to store different types of data in a database. Here are the data types that Salesforce supports:

A. Primitive Data Types: Primitive data types are the basic data types that store single values. Salesforce supports the following primitive data types:

1. Integer: This data type stores a whole number.
2. Double: This data type stores a decimal number.
3. Date: This data type stores a date value.
4. Datetime: This data type stores a date and time value.
5. String: This data type stores a text value.
6. Boolean: This data type stores a Boolean value (True or False).
7. ID: This data type stores a record ID.
8. Decimal: This data type stores a decimal number with a fixed number of decimal places.
9. Currency: This data type stores a currency value.

B. sObject Data Type: sObject data type is used to represent any standard or custom object in Salesforce. It is used to create, retrieve, update, and delete records in the database.

C. Collections Data Types: Collections are used to store multiple values of the same data type. Salesforce supports the following collection data types:

1. List: This data type is used to store an ordered collection of elements of the same data type.
2. Set: This data type is used to store a collection of unique elements of the same data type.
3. Map: This data type is used to store a collection of key-value pairs.

D. Null Data Type: Null data type represents a variable with no value.

Option B is not a valid answer as it represents SOAP web service callouts which is not a data type. Option C represents a List of List objects which is a specific type of collection, and not a separate data type. Option D represents HTTP methods for RESTful web services and not a Salesforce data type.

Therefore, the correct answer is A which includes all the valid Salesforce data types.
