Efficient management of 2-d interval relations,We identify a number of problems concerning the management of interval data and propose efficient algorithms in the case of 2-dimensional . relations. The approach is of practical importance and has many applications, one of which is spatiotemporal databases.

The R-link tree: A recoverable index structure for spatial data,So far, R-trees have been investigated for use in the single-user environment. We use the link technique proposed by Kung and Lehman to support concurrent operations (search, insert, and delete) on an R-tree. We present algorithms for implementing these operations, and also discuss recovery issues in case of failure.

Peplomd: an object oriented database programming language extended with deductive capabilities,clean integration of a deductive query language within a procedural language and the support of derived data. The language, offers at the same time an imperative part, for structuring and writing the bulk of applications and a declarative part, for writing expressions and queries necessaries when handling large amount of persistent data.

A generalized semantic model for CSCW systems,based on both theoretical foundations as well as empiric principles. A three level model is proposed, a high level interaction model, a detailed elaboration of model constructs and behaviour based on state transitions.

Mohamed Sellami,Paolo Ceravolo,Hervé Panettocepts of query languages, and analyse the query facilities of the systems. The analysis leads to a classification of query languages, precisely differentiating the capabilities. Further aspects concern the embedding and the style of query formulation. The comparison is based upon empirical evaluations.
