: Documents such as spreadsheets are easy to create, edit, and exchange. However, their use causes a set of well known problems such as poor data quality, lack of multi user support and missing data in backend systems, e.g. for data analysis. In this paper we present our smart file prototype that extends proven concepts from DBMS to the desktop document dataspace. Firstly, we show how documents can be handled as db-objects using materialized external views. Secondly, we show how documents can be turned into a DBMS themselves.
