USER DRIVEN BUSINESS DATA AGGREGATION AND CROSS MAPPING FRAMEWORK

An approach is provided for aggregating business data. Based on received columns, attributes, and keys of a dataset, the dataset is registered in a central hub of datasets which include data that is independently and locally maintained. Initial or updated data is loaded into the dataset in the central hub. Other datasets in the central hub that include columns, attributes, or keys that match the received columns, attributes, or keys, respectively, are determined and displayed. In response to receiving a user selection of one or more of the displayed datasets, cross-links between the dataset and each of the one or more selected datasets are automatically generated. The cross-links are based on the columns, attributes, or keys of the displayed datasets that match the received columns, attributes or keys. The cross-links provide an aggregation of business data in the dataset and the one or more selected datasets.
