Implementation of Valid-time Indeterminacy in Temporal Clinical Databases

Temporal indeterminacy is an inherent problem which arises when capturing and manipulating temporal data in many application areas. However, the issue of implementing a temporal query language that can support temporal indeterminacy has not been addressed so far. In this paper, we represent our approach to implementing valid-time indeterminacy in temporal clinical database systems on top of a commercial relational DBMS
