Abstract:
A method in a computer system for updating data sets, the method comprising:when generating a data set, monitoring the generation of the data set and recording an identification of a service used to generate the data set and an identification of input data sets for the generation of the data set; and when the data set is accessed, determining whether the input data sets are up-to-date; when an input data set is not up-to-date, regenerating the input data set that is not up-to-date using a service whose identification was recorded when the input data set was generated and indicating if the input data set has changed; and when an input data set has been changed since the data set was last generated, regenerating the data set by using the identified service and the identified input data sets to generate an up-to-date data set.
