Abstract
The invention relates to a method for synchronization of source data sets of a source database stored on a source system with representative target data sets in a target database database database stored on a target system, the source data sets being of a first type and the target data sets being of a second type. The source data sets are compared with the previous source data sets to obtain difference source data sets of the first type. The difference source data sets are transformed into transformed data sets of the second type and supplied to the target system to enable updating of the representative target data sets. Preferably, the transformation is performed via data sets of a third type, which allows to implement external business generation. To add fully transparent a new source of target database to a business information system using the method only the conversion from data type of the new source database to data sets of third type and/or conversion from data sets of third type to data type of target database has to be developed.

13. A method for synchronization of source data sets of a source database stored on a source system with representative target data sets in a target database stored on a target system, the source data sets being of a first type and the target data sets being of a second type, the method comprising:
-
(a) retrieving source data sets; (b) retrieving previous source data sets from a first memory; (c) comparing the source data sets with the previous source data sets to obtain difference source data sets of the first type; (d) replacing in said first memory the previous source data sets with the source data sets; (e) transforming the difference source data sets into transformed data sets of the second type; (f) supplying the transformed data sets to the target system to enable updating of the representative target data sets. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

24. A computing system for synchronization of source data sets of a source database with representative target data sets in a target database, the computing system comprising:
-
input means (302) for receiving source data sets from a source system; at least one processor (318) for generating a transformed data sets; a processor readable storage medium (312) comprising executable instructions which instructions when executed on said at least one processor perform the method comprising; (a) retrieving source data sets; (b) retrieving previous source data sets from a first memory; (c) comparing the source data sets with the previous source data sets to obtain difference source data sets of the first type; (d) replacing in said first memory the previous source data sets with the source data sets; (e) transforming the difference source data sets into transformed data sets of the second type; (f) supplying the transformed data sets to the target system to enable updating of the representative target data sets; output means (308) for supplying the transformed data sets to a target system to enable updating of the representative target data sets.
