Abstract: In Business Intelligence systems, data warehouse metadata management and representation are getting more and more attention by vendors and designers. The standard language for the data warehouse metadata representation is the Common Warehouse Metamodel. However, Business Intelligence systems include also Approximate Query Answering systems, since these software tools provide fast responses for decision making on the basis of approximate query processing. Currently, the standard meta-model does not allow to represent the metadata needed by Approximate Query Answering systems. In this paper, we propose an extension of the standard meta-model, in order to define the metadata to be used in On-Line Approximate Analytical Processing. These metadata have been successfully adopted in ADAP, a web-based Approximate Query Answering system which creates and uses statistical data profiles.
