Answer:- Visualforce can be defined as the user interface for the Force.com platform. It is a component-based framework that can include over 100 in-built components. It includes a tag-based markup language, and each Visualforce tag corresponds to a page or a field. The Visualforce framework works on the standard MVC paradigm. It is possible to have tight integration with the database and also deploy auto-generated controllers for database objects. Developers can use Apex codes to write their own controllers.

Data Manipulation Language (DML) operations can be performed on the query results. • Salesforce Object Search Language (SOSL) lets us search for multiple objects. But, in SOSL, we can query only for texts, emails, and phone numbers. Also, DML operations cannot be performed on the search results.

Answer:- • Standard Controllers: Standard Controllers are created for all standard Salesforce pages. They consist of the same logic and functionalities that are utilized in any standard Salesforce page. They can be easily utilized with both standard and custom objects. • Custom Controllers: Custom Controllers is a class written in Apex and it overrides the standard functionality of a standard controller of a page. It executes the logic of a page without utilizing the Standard Controllers. We use custom controllers whenever we want to run a Visualforce page fully in system mode, which means that the security and permissions of the current user will not be recognized.

Answer:- A standard field record consists of either auto-number or text field, read-only data type with a maximum limit of 80 characters.
