Force.com database | Standard Field Types in Salesforce
Force.com platform is one of the powerful and acts as a intuitive data persistence layer baked into all aspects of platform. The Force.com database not only acts as a persistence layer but also it generates user interface for creating, updating and displaying records. Non-technical users who don’t know coding can also create, configure and deploy persistent objects using the point-n-click, form-based interface in the Setup environment.
Salesforce.com takes a slightly different approach with their database layer. Instead of coming from a pure database perspective, the Force.com database takes a more abstract approach and represents everything as objects. Traditional database like Oracle, SQL, MySQL has tables and columns where Force.com database is composed with objects and fields.
