In this paper we are concerned with the problem of designing of a conceptual framework for the construction of a flexible query answering mechanism that is adequate for selecting useful answers to queries, considering a multi-source and conflicting community of information sources. We put forward a proposal to provide representations with that kind of functionality through flexible reasoning mechanisms for handling query descriptions and retrieving perspective answers. We start by positioning conceptual schema, database with regard to this problem. Then we distinguish evidential assessment as the central task in query answering considering the conceptual, instance level always with respect to the dynamism-dimension of data.
