Huseyin Haci,Huiling Zhu,Jiangzhou Wang how to use constraints for the processing of queries that contain user-defined functions. Such functions are a common feature in many extended and object-oriented database applications. By representing knowledge about the functions through constraints, the efficiency of query optimization and execu

Mürsel Yildiz,Manzoor Ahmed Khan and Kornatzky. We augment Brodsky and Kornatzky‘s model with a few simple primitives, that would make querying the model simpler and more natural. Our basic model is quite similar to the Brodsky and Kornatzky‘s model but, by the introduction of the notion of a ., the modelling of part-subpart relat

The main idea is to optimise complex queries by continually checking to see if the current partial results are consistent with the remainder of the query..In this paper we present a query lang
