Abstract: A method and computer-readable storage medium for performing the method of creating a business process workflow user interface (“activity form”) featuring process data and process-related data where no manual coding is required to integrate different data sources into the user interface. An activity form associated with an activity from a business process workflow is created with at least one field associated with an operand of the related process definition. A relationship is specified with at least one operand and at least one process-related data source.

Abstract: An indexed sequential file is made accessible for random or sequential reading of records while allowing concurrent modification to the file. Each ordered group of records in the file is associated with timestamps referencing a deletion time of the group and the time that the group was last modified. During a current search in a group for a desired record, the timestamp referencing a deletion time of the group is compared to a search time established at the beginning of the search. For a sequential reading the timestamp referencing a last modification time of a group containing the desired record is compared to a respective timestamp corresponding to the reading of the preceeding record. The comparisons provide indications of whether the group to which the desired record belongs is currently the group to be searched. The most recently modified and deleted groups are stored in a cache memory.
