Represents a connection to an UltraLite database.

Connections are instantiated using one of the following methods:

• DatabaseManager.openConnection
• DatabaseManager.createDatabase

You must open a connection before carrying out any other operation, and you must close the connection after you have finished all operations on the connection and before your application terminates.

You must close all tables opened on a connection before closing the connection.

When a JavaScript Error is thrown because of a failed UltraLite database operation, the SQL error code is set on the sqlCode field of the Connection object.
