Abstract: Systems, methods and computer program products for determining a list of products in response to a client request received from a client device during a request/response session. Occurrence frequency and auxiliary product value information for each auxiliary product set in a list of auxiliary product sets are determined from a tree data structure in response to a client request. A list of candidate auxiliary products for each main product is determined using the occurrence frequency and a service value determined for each auxiliary product set in the list of auxiliary product sets.

Abstract: In one aspect thereof the exemplary embodiments provide a data processing system that includes at least one data processor; at least one memory connected with the data processor and that stores computer software that is executable by the at least one data processor; at least one database storing a plurality of fares and rules establishing conditions under which at least one of the fares can be applied; and an interface to at least one user and configured to receive from the user a fare inquiry. The data processor is configured with the computer software to cause the data processing system to receive a fare inquiry that contains at least one rule attribute, to perform a first search to determine rule data applicable to the at least one rule attribute, and to perform a second search using the rule data to retrieve a list of fares that are applicable to the rule data.

Abstract: A method and system for processing data for database modification, include receiving a set of data, performing a processing chain including a plurality of consecutive jobs to transform the set of data into transformed data, modifying a production database with respect to the transformed data and further include the steps of setting a target processing time for the performance of the consecutive jobs, before a launch of a first job, applying an original configuration as current configuration defining a parallelization level for each of the consecutive jobs, before a launch of at least one further job after the first job, upon an actual remaining processing time being out of a range of acceptable remaining processing times, applying an adapted configuration as new current configuration defining an adapted parallelization level for each of the jobs remaining in the processing chain, the adapted configuration differing from the current configuration.

Abstract: A method for updating data to ensure the correct version of the data is available for a user of a second data system. In the second data system, an update request is received from a first data entity to update the data in a component of the second data system. The update request comprises an updated version of the data. The updated version of the data is compared with a currently stored version of the data in the second component to determine a change therein. An operating function representative of the change in the data is produced. The operating function is applied to the currently stored version of the standard data to produce resulting data. The operating function is stored to ensure the correct version of the data is capable of being output if requested.
