The driver automatically maps Salesforce objects and fields to tables and columns the first time it connects to a Salesforce instance. The driver maps both standard and custom objects and includes any relationships defined between objects.The driver uses a local embedded database to instantiate the mapping of the remote data source objects to tables and the metadata associated with those tables. The driver creates a database per user. The embedded database is created in the directory from which the application is run and uses the user ID specified for the connection as the name of the database. If the user ID contains punctuation or other non-alphanumeric characters, the driver strips those characters from the user ID to form the name of the database. The driver provides connection options that you can use to override the default setting for the name and location of the database (Database).
