Abstract
Systems and methods are provided for extracting data sets from an online relational database into a data warehouse. A data query based on special timestamping technique is executed. Timestamping allows extraction of only these data sets that have changed since the last extraction point. The data sets that have been already imported stay unchanged and do not need to be deleted at the time of the new import. Extraction interval of data sets including a time window enclosed by lower and upper limits is defined. The extracted data sets that have been imported twice may be filtered out with the use of, for example, an operational data store (ODS) objects. The filtered out data sets may be available in the data warehouse for the drilldown reporting.
