In this paper, the authors focus on the following problem in information management: given a large collection of recorded information and some knowledge of the process that is generating this data they want to build a compact, non-redundant collection of summary (aggregate) tables and indices to facilitate flexible decision support analysis. The additional knowledge is depicted as a graph called the sketch that is supper-imposed over the process and indicates particular parts that they want to analyze. They first show how to select a minimum set of views to answer queries with path-expressions over the given sketch. For queries that also include aggregations, they define two partial orders among the views.
