Methods, articles of manufacture, and systems for determining a fee to be charged for requests processed in a grid computing environment based. In one embodiment the fee may be determined based on the time it takes to process a request and/or pricing schedules that may vary depending on a variety of pricing criteria. In another embodiment, a completion time criterion that defines a maximum acceptable time to complete a request may be specified. If the amount of time needed to perform the request is less than the maximum acceptable time specified, returning the results may be delayed to avoid providing services valued in excess of what the customer has paid for.

A method, system and article of manufacture for query execution management in a data processing system and, more particularly, for managing execution of queries having one or more related query conditions. One embodiment provides a method for managing execution of a query against data of a database. The method comprises receiving a current query against the data of the database, the current query including a plurality of query conditions, for each query condition of the plurality of query conditions, determining whether a previously generated dynamic bitmap index can be re-used for the query condition of the current query, the dynamic bitmap index having been previously generated for a previous query condition associated with a previous query executed against the data of the database; and if the dynamic bitmap index has been generated for the previous query condition, retrieving the dynamic bitmap index, and determining a query result for the current query using all retrieved dynamic bitmap indexes.

A method, apparatus, system, and signal-bearing medium that in an embodiment replace an element in a query with a backup if the element is not available, but the backup is available. An element may also be removed from the query if the element is not required. In various embodiments, the element may be a table or a user-defined function. In this way, the query may still execute even if the element is not available.

A system, method and article of manufacture for presentation of data on a display device and, more particularly, for managing presentation of data in a tabular form on a display device. One embodiment provides a method of managing display of requested data on a display device. The method comprises, in response to a request for data, receiving the requested data in a tabular form having a plurality of columns and rows ordered according to an initial order; re-ordering at least one of the columns and rows, wherein the re-ordering is done on the basis of rules configured to intelligently arrange presentation of the requested data to a user; and outputting the re-ordered requested data for display on the display device.

A method, apparatus, system, and signal-bearing medium that in an embodiment track a history of statements that query data from a database. When a new statement is received, the history is searched for a correlation between the new statement and previous statements. The correlation is based on host variables in the history and the new statement. When a correlation is found, a prediction is made for the next statement to be received based on the previous statement in the history for which the correlation was found. The prediction is then used to retrieve pages from the database into a cache, which may be used by a subsequent statement.
