Writing Resistance in the Second World Warf the location-dependent attribute in a particular location. We extend concept hierarchies to include spatial indexes on the location-dependent attributes. Finally, we discuss how to partition and replicate relations based on the location to process the queries efficiently. We briefly discuss the implementation issues.

Managing Schemata for Semistructured Databases Using Constraintshema containment and describe how to test this condition, again, using constraints. We show how the knowledge of schema containment can be used for optimization. As a theoretical contribution we prove that, under some circumstances, schema matches can be found without any backtracking and in polynomial time.

A New Algorithm for Page Access Sequencing in Join Processingbetter than existing heuristics for data which is modelled with geometric graphs, and no worse in others, for the first problem. It performs similarly better for the second problem if the fixed buffer size is not much less than the maximum buffer size generated in the first problem.
