The interaction between recursion in XPATH and recursion in DTDs makes it challenging to answer XPATH queries on XML data that is stored in an RDBMS via schema-based shredding. We...
Abstract. The classical work on test case generation and formal methods focuses either on algebraic or model-based specifications. In this paper we propose an approach to derive t...
We present a completion procedure (called MKB) that works for multiple reduction orderings. Given equations and a set of reduction orderings, the procedure simulates a computation ...
We follow the stack-baaed approach to query languages which is a new formal and intellectual paradigm for integrating querying and programming for object-oriented databases. Queri...
