Conference proceedings 1988h in database theory worldwide. Most major themes of research in database theory are covered in ICDT ‘88: the relational model, logic and databases, object-oriented databases, deductive databases, conceptual models, analysis and design of data structures, query languages, concurrency control and updates and transactions.

Data models and languages for databases, manipulate structurally complex objects and their languages. The emphasis is on formal models and languages. In particular, we describe a formal model for objects with identity, and declarative languages for the model.

On using conditional rotation operations to adaptively structure binary search trees,ost of the tree is reduced by each restructuring operation, and present experimental results to demonstrate the superiority of our algorithm over all other reported efficient static and dynamic schemes.

Two-way join optimization in partitioned database systems,ect of local semijoins and remote semijoins as reducers. Finally, computational experiments are carried out to investigate the trade-off between the computation time and the quality of solutions as well as to analyze the sensitivity of the solutions to various parameters of our model.

Idempotent single-predicate horn clauses,bleau queries with recursive semantics. The study of the idempotence and boundedness for single-clause, single-predicate queries has previously been restricted to the typed case. We generalize these results to obtain syntactic, polynomial-time computable characterizations of idempotence for certain classes of untyped queries.
