# Database

We are going to explore two ways how to access database from Grails from Vaadin code. The first approach to access database is GORM (Grails Object Relation Mapping). GORM is the defualt way to access database in Grails.

The second part of Database section shows how to integrate Grails with other than GORM database frameworks and how to use it in Vaadin code.
