examines documents that use the data in question such as reports or, in this case, research
papers, to extract information about which data is effectively used in what way. Because the documents are written
products of actual data use, this method delivers valuable information, but it is not sufficient since the aim of the
warehouse is not limited to the recreation of existing reporting capabilities. Furthermore, the results can be
misleading because the documents usually do not contain context information explaining why specific data was used
in a certain way. Therefore, it should be supported by face to face methods, but it offers a good way to gather initial
insight before starting other activities (Kimball, 2008, pp. 67, 70).
