Open takes as input a property set of connection properties that specify the workspace to connect to. In the case of file system workspaces and local database workspaces, a single property named DATABASE, whose value is the pathname to the workspace, is usually all that is required. In the case of remote database workspaces accessed via ArcSDE the properties can include the USER, PASSWORD, DATABASE, SERVER, INSTANCE, VERSION, HISTORICAL_NAME, HISTORICAL_TIMESTAMP, and AUTHENTICATION_MODE properties of the database being connected to.
