Create ( string adminName, string identification, string token ) : void	Creates the database in the context given, granting the administrative control to the user identified by the given name and token. The properties used to create the database are extracted from the underlying context (DatabaseContext). This method does not automatically open the database: to make it accessible a call to Open is required.

Private Methods

Méthode	Description
AssertDataVersion ( ) : void
Close ( ) : void	Closes the database making it not accessible to connections. Typical implementations of this interface will automatically invoke the closure of the database on disposal (IDisposable.Dispose.

OnDatabaseCreated ( IQuery context ) : void
Open ( ) : void	Opens the database making it ready to be accessed. This method ensures the system components and the data are ready to allow any connection to be established. After this method successfully exists, the state of IsOpen is changed to `true`.
