Abstract: A typical data warehouse report is the dynamic representation of some objects’ behaviour or changes of objects’ properties. If this behaviour is changing, it is difficult to make such reports in an easy way. It is possible to use the fact splitting to make this task simpler and more comprehensible for users. In the presented paper two solutions of splitting facts by using weights are described. One of the possible solutions is to make the proportional weighting accordingly to splitted record set size. It is possible to take into account the length of the fact validity time period and the validity time for each splitted fact record.
