Abstract
A computer-implemented method for joining two data tables on a join attribute, where the data tables have at least a first and a second attribute and the second attribute is the join attribute. The method provides a function for associating a computing node to a given record. The function may be used to determine the associated computing node. The records of the two data tables may be distributed to the respective determined computing nodes. The relationship between the values of the first and second attributes may be modelled using a predefined dataset. For each record of the two data tables the values of the first attribute may be re-determined using the corresponding values of the second attribute. The function may be used to re-determine the associated computing node.
