Abstract: A method is provided for preventing dark data in a data set. At a time t1, a first version of the data set is received. The first version is analyzed and its parameters are gathered in a first statistical profile. The first statistical profile is stored. At a time t2, a second version of the data set is received. The second version is analyzed and its parameters are gathered in a second statistical profile. The second statistical profile is stored. The first and second statistical profiles are compared and a similarity index is created. If the similarity index exceeds a pre-set threshold, dissimilarity is flagged and a responsive action is taken.

Abstract: A method is provided for ingesting datasets into existing data warehouses, which are associated with data warehouse references. A selection of a data warehouse reference into which a dataset is to be loaded is received from a user. The dataset is accessed and its regional and format particulars are determined. Available data warehouses associated with the selected data warehouse reference are determined. Based on the regional and format particulars, a data warehouse is selected from these available data warehouses. A current address of the selected data warehouse is retrieved. The dataset is ingested directly into the selected data warehouse at the current address without further input from the user or knowledge of the current address by the user. A method of migrating between existing data warehouses with ingested data is also provided.
