Abstract: According to exemplary embodiments, a dishwasher or other washing appliance includes a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain fluid from the dishwasher or other washing appliance. The siphon break apparatus may include a body portion that may be divided by a filter into a filter chamber and a flow chamber. The filter chamber may extend perpendicularly from the flow chamber. An aperture may be defined in the filter chamber and sealed shut by a domed closure of a normally-closed umbrella valve. The domed closure may unseal from the aperture and thereby allow air to enter the filter chamber, travel through the filter and into the flow chamber so as to relieve a low pressure region and substantially prevent a siphon effect in the fluid conduit. A related method is also provided.

Abstract: A method, apparatus, and computer program product in a data processing system for avoiding excessive database round trips. A list of a database object fields affected by queries is compiled by analyzing instructions in a database query language. A list of database object fields affected by queries is also compiled by analyzing database object relationships. Using the combined list of affected database object fields, when a find operation is invoked, a determination is made as to whether the affected database object fields have been modified. Next, if the affected database object fields have been modified, database updates are generated for the affected database objects containing the affected database object fields. After that, the database updates are executed after all affected database object fields have been processed. Finally, the queries are submitted.
