Declarative Vs Programmatic Approaches
You can develop a salesforce using any one of the approaches either declarative or programmatic. In declarative approach you make use of page layouts, record types whereas in programmatic approach visualforce pages and components are used for developing a user interface. Workflow, validation rules, approval process, are included in the business logic when you incorporate a declarative approach. When you go for a programmatic approach for the business logic of the application make use of Apex triggers, controllers and classes.
The data model of the Salesforce application can be created using objects, fields and relationship in the case of the declarative approach. Metadata API, REST API, Bulk API are used for data modelling with a programmatic approach.
Knowing About Visualforce

The custom logic is developed or written using Apex. It is an object-oriented language and makes use of flow and transaction control statements in Force.com platform. If you’re familiar with Java programming, then Apex programming would become simple. This is because nearly 70% of the Apex syntax is the same as that of Java.
